Worn Armor

General Rules

Worn Armor is represented on a player by actual pieces of physical armor worn by the player.

Worn Armor generates Armor Points based on the average Each piece is given an individual Armor Rating and then the Hit Location is assigned its Armor Point value based on the ratings of the different pieces covering it.

See the Armor Construction section for details about how to craft and calculate armor points.

Worn Armor Limits

The maximum amount of Armor Points a player can ever receive from Worn Armor in Amtgard is six (6). Some game types, such as Class battles, will further limit this amount. In all cases, armor point values are reduced to their allowed maximum value after averaging and any other post-averaging modifiers, such as Helms. Natural Armor and Magic Armor are unaffected by these limits.

Example:
Ariq is playing a class which is limited to 3 armor points maximum for a class game. He is wearing armor that grants him 4 points on his torso, 2 points on his arms, and 1 point on his legs. Since his class has an armor limit of 3 points, Ariq's torso armor is reduced to 3 points for the duration of that game. His arm and leg values are unchanged.

Worn Armor Visibility

All Worn Armor pieces must be at least partially visible in a way that does not misrepresent the wearer’s potential armor point value and/or coverage when observed by another player. (see HSR #2)

Adding/Removing Worn Armor During a Game If it is necessary to add or remove pieces of Worn Armor after a game has started, the new Armor Point Values should be recalculated and adjusted as soon as reasonably possible. (see the V9: Equipment - Construction for details about how to calculate armor points)

If armor point values are adjusted while the player is still alive, their maximum and current values are adjusted equally. If the current value is 0 and a piece is added, the armor point value only increases if it is a completely fresh piece of armor that has not been previously worn that life.

Rating Armor & Calculating Armor Point Totals

Rating Armor Pieces

Each piece of Physical Armor must be inspected and given an Armor Rating in order to be used for Amtgard combat.

1. Physical Armor pieces must be examined and rated by an Equipment Inspector.
2. Each piece of physical armor will be assigned to an Armor Tier based on its style that will outline its Base Armor Rating and Maximum Armor Rating. Armor that cannot be assigned to a tier does not count as armor and cannot be used as such.
3. Pieces can be granted bonuses or penalties based on the quality of construction or appearance.
   • The sum total of all modifiers cannot increase a piece's armor rating beyond the maxiumum allowable for its tier. Surplus bonuses confer no additional benefit.
   • Armor with a final rating of zero or less (due to penalties) does not count as Armor and cannot be used as such.
4. Armor Pieces are rated individually but will be averaged together when worn to produce an Armor Point Total for each Hit Location.

PRO TIP: EQUIPMENT REFERENCE SHEETS
Armor rating can be subjective at times. To help mitigate this, it is recommended that players keep a reference sheet with a list of details for their physical armor pieces including descriptions, construction details, and previously assigned ratings to help Inspectors make quick and confident assessments. Keeping signatures and inspection dates from other Inspectors will add further credibility to your notes.

Reference Sheets are not necessary but they will greatly improve your odds of getting consistent armor ratings at every event you attend!

Armor Tiers

Armor tiers provide a base and maximum rating for physical armor pieces. Each tier includes a list of common styles that fall under that tier. Ambiguous armor pieces should be placed wherever they would be most appropriate.

ARMOR TIERS
TIER	BASE RATING	MAX RATING	INCLUDES
T1	1	2	Cloth/Padded
T2	2	3	Light Leather & Synthetic Variants Butcher's Mail, Sharkmail, and similar.
T3	3	4	Heavy Leather & Synthetic Variants Rigid Non-Metal Armor Chainmail
T4	4	5	Light Scale
T5	5	6	Heavy Scale Butted Plate (Splint, Kikko, etc.)
T6	6	7	Lamellar, Laminar Brigandine Plate
Special	-	-	Ambiguous Armor

---

Armor Modifiers

Armor pieces can be granted bonuses or penalties to their Armor Rating based on the quality of construction or appearance. Multiple points can be awarded and penalized simultaneously as long as they each correspond to each unique feature or collection of features that would warrant the bonus or penalty if viewed on its own.

Superior Appearance
Bonus points may be awarded to armor that displays an exceptional appearance above and beyond the typical appearance of similar pieces in its style. This includes but is not limited to: tooling, etching, gilding, and fluting, as well as notable use of colors, shapes, weaves, etc. These examples do not represent an exhaustive list and consideration should be given to any piece that obviously goes above and beyond the base construction requirements to create an aesthetically pleasing piece.

Inferior Appearance
Points may be deducted from armor that displays an appearance well below the typical standard expected for similar pieces in that style. Examples include tarnished/poorly-maintained armor as well as visibly inauthentic or degraded materials. This penalty does not apply when the piece is worn as a part of a complete outfit that is intentionally designed to look shoddy or battle-worn.

Superior Construction
Bonus points may be awarded to armor constructed with exceptional techniques that provide a meaningful increase in durability over the standard for the material being used. This includes but is not limited to: solid/riveted rings, hardened material, noticeably tighter spacing than required, etc. These examples do not represent an exhaustive list and consideration should be given to any piece that obviously goes above and beyond the base requirements to create a more durable piece. This bonus may also be granted to pieces that are at least 75% constructed from metal materials that are significantly more dense and/or durable than aluminum.

Inferior Construction
Points may be deducted from armor for inferior construction techniques or a meaningful reduction in expected durability when compared to the standard for the material being used. Examples include but are not limited to: obviously unfinished armor, brittle/cracked material, loose connection points, and shoddy workmanship.

Layered Armor Bonus
If multiple unique pieces of Physical Armor are layered on top of each other as part of a complete outfit, the rating of any overlapping area will be rating of the highest-tier armor piece plus 1, up to that armor’s maximum.

1. A piece of armor already at max rating will not receive any additional value from layering.
2. Each layered piece should be able to act as armor on its own if it were not layered. The layers may be affixed while being worn, such as metal armor attached to an arming doublet.
3. Any part of layered armor that extends beyond the layering is calculated at its normal rating.
4. All layered armor pieces must be at least partially visible in a way that does not misrepresent the wearer’s armor point total or armor coverage when observed by another player from 20ft away. This especially true in the cases where a lower-tier armor is layered on top of a higher-tier piece.
5. There is no additional bonus for layering more than two pieces.

Material Thickness

Certain armor styles may require materials that meet a specific thickness. Multiple layers of material may permanently affixed to each other to increase thickness however extra thickness caused by adhesives or empty space should not be factored into the new measurements.

• One bonus point may be awarded or deducted for Superior or Inferior thickness according to the chart below.
• Armor pieces that do not meet these minimum requirements may be judged as Ambiguous Armor as long as they still meet the universal equipment requirements.

Supplemental Armor Bonus

Player with Supplemental Armor

When calculating a player's Armor Point Total, armor worn on the head (above the neck), hands (above the wrist), or feet (below the ankle) do not contribute a normal rating towards calculations. Instead, pieces that meet the construction criteria below grant an additional +1 bonus to their respective location (torso, right arm, left arm, right leg, left leg) after all Armor Point Totals have been calculated.

1. Supplemental armor pieces must cover at least 50% of the surface area of the head, hand, or foot, not including space between fingers and toes.
2. They meet the Universal Equipment Requirements, as well as be constructed in a way that would place them in Tier 3 or greater.
   • To ensure safety in the cases of accidental hand contact, hand armor cannot include metal or similarly rigid materials on the tops of knuckles or fingers, including fingertips. To offset this, Hand Armor can also be constructed as a Tier 2 armor so long as the final piece still looks like armor.
3. This bonus can cause the armor point total to exceed tier maximums, however it will still be affected by armor point limits imposed by class or game modes.
4. If hand or foot armor is the only armor piece worn on that location, then it should be compared to the normal armor tiers and assigned a normal rating as best as possible.

---

Calculating Armor Point Totals

Once the pieces are rated, Armor Point Totals are calculated for each Hit Location based on those ratings and the approximate physical coverage that each piece bestows.

To calculate this total, average the ratings of all physical armor pieces in the hit location based on the percentage of coverage they provide, rounding the result to the nearest whole number.

• Areas not covered by any armor whatsoever, such as gaps or garb, are not factored into this averaging.
• You do not need to be precise when determining the coverage. "Eyeballing" it is perfectly fine and is even encouraged as long as it is done in good faith.

Once the point total has been calculated, any extra points from Supplemental Armor should be added.

Example: Padded Bracer, Chainmail Sleeve, and Gauntlets.

Lorathana is wearing a cloth bracer (rated 2pts) on her right forearm, a chainmail tunic (rated 4pts) with sleeves covering some of her arms, and a leather gauntlet. The two pieces together cover about 70% of her arms, leaving a gap at the elbow.

To make their calculations, the Equipment Inspector only has to focus on the area covered by armor. Looking at her arm, they determine that the bracer takes up about 40% of the armored area and the chainmail sleeve takes up about 60% of the armored area. The Gauntlets are Supplemental Armor so they are ignored until later.

[Bracer] 2pts x 40% = 2 x 0.40 = 0.8
[Sleeve] 4pts x 60% = 4 x 0.60 = 2.4
0.8 + 2.4 = 3.2 rounds down to 3.

Now that the total has been calculated, Lorathana can add the Supplemental Armor bonus for her Gauntlets, granting an additional +1.

Therefore, Lorathana’s right arm has an Armor Point Total of 4pts in the areas covered by armor (the bracer, the sleeve, and the gauntlets) and an exposed gap between them.

The plates are typically placed on the inside of the shell, presenting only fabric and rivets to the observer for a very clean and customizable appearance.

• Is a Tier 6 armor style.
• Must meet the Universal Equipment Requirements.
• 75% of plates must overlap by at least 10% of their surface.

Plate armor will not deform locally when struck, and will instead behave as a single contiguous whole. The individual metal pieces are shaped and fitted to articulate together and follow the contours of the body.

• Is a Tier 6 armor style.
• Must meet the Universal Equipment Requirements.
• 75% of the plates used must be large enough to cover at least 10% of the full Hit Location. Joint articulations are exempt from this requirement.

Ambiguous Armor

Placeholder Example

For armor pieces that are ambiguous, the equipment inspector should compare it to each tier as a whole and do their best assign to the tier they feel is most appropriate based on factors such as materials, weight, flexibility, and visuals (see guide below).

• Inspectors should reference similar styles and materials to help gauge what bonuses or penalties may be appropriate.
• Ambiguous Armor must still meet the Universal Equipment Requirements.

Below is a simple guide that inspectors may use to gauge the best tier for an ambiguous piece of armor. Use this knowledge alongside existing styles to help place the armor in a tier that is fair for everyone.

1. Non-Metal Tier Cap: Non-metal armors should not be placed higher than Tier 3, regardless of the factors below.
2. Weight: Heavier armor should be placed higher, but only to a limit. The lowest tier armors are quilted cloth (0.03 lbs/sqft) and the highest tier armors are 14ga aluminum plate (approx. 1 lbs/sqft). Extra weight beyond these bounds should receive no additional consideration, however steel-like materials may receive a separate construction bonus afterwards. Weight added for no reason other than to add weight should likewise be disregarded.
3. Flexibility: The more rigid the armor is, the higher it should be placed. The lowest tier armors are fabric and the highest tier armors are reinforced metal plates.
4. Tiebreaker - Visuals: If there is difficulty deciding between two tiers, visual appearance can act as a tiebreaker to nudge the decision one way or the other.
5. Helpful Benchmarks: Consider using these benchmarks to help peg an initial placement and then fine tune it using the other criteria above.
   • Ambiguous armor that meets the universal equipment requirements is always eligible for Tier 1 at minimum.
   • Ambiguous armor that is primarily rigid and non-metal should be placed roughly around Tier 2 or Tier 3.
   • Ambiguous armor that is primarily metal and primarily rigid should be placed roughly around Tier 4 or Tier 5.

Note to Players: Buying or crafting ambiguous armor pieces can make your ratings inconsistent. To help mitigate this, consider keeping an Equipment Reference Sheet to help inspectors view previously assigned ratings so they can make quick and confident assessments. Keeping signatures and inspection dates from other Inspectors will add further credibility and stability to your ratings.
