Kanohi
For several species in the Matoran universe, Kanohi - specially-designed masks made from purified metallic protodermis - are an integral part of day-to-day life. Matoran, for example, must wear a Kanohi mask at all times; without one, they will grow weak and eventually fall comatose within a matter of hours.
When forged using rare and sufficiently-purified materials, Kanohi masks can grant their wearers all sorts of powers and abilities if the user is capable of accessing them. If a powered Kanohi is cracked or broken, its power will leak out, causing it to stop working entirely; a few particularly powerful masks may malfunction if damaged. Kanohi are attached to the faces of their wearers via a magnetic connection.
Properties
Power levels
Kanohi masks come in several different types: powerless, Noble, Great, and Nuva.
While powerless masks only provide the wearer the small amount of energy needed to prevent the adverse effects of masklessness, all other types of masks grant a specific power to their wearers if they are able to use them. Mask powers can only be accessed by certain species, and even then, require significant amounts of focus, mental discipline, and willpower to activate, often necessitating special training in order to do so.
Noble masks provide minor powers, and are sometimes more limited than their Great counterparts. Great masks offer substantial power, and some beings may choose to predicate their main strategies for battle off of a single Great mask. Nuva masks are special, powerful forms of Noble or Great masks, only usable by beings who have been transformed into Nuva; the abilities these masks provide often have additional advantages and benefits, and can be shared with beings near the user.
Three unique masks sit at a power level above all others: Legendary. These masks control fundamental aspects of the universe - Life, Creation, and Time - and will have devastating to catastrophic results if misused, or worse, broken.
Shapes
Each Kanohi power has a standard "shape" associated with it and its power level (other than powerless). Conventionally, most masks are forged in the shape that matches their power and power level for the sake of quick identification, but a mask can technically be made in a different shape for any number of reasons (for example, to honor an old hero or lost friend, or more nefariously, to hide the mask's true power). Powerless masks are generally forged in one of the standard shapes for their associated power.
Masks may vary from their standard shape in a variety of ways. Some are modified to be better-suited for specific environments, and a number of enhancements (such as scopes or visors) or cosmetic attachments can be added to a mask by a sufficiently-skilled mask maker.
Most masks (unless modified, painted, etc.) are a dull gray when they are not being worn. When worn, a Kanohi mask will take on the colors of its user.
Other
Over time, Kanohi take on an inactive "imprint" of their wearer's consciousness, which then gradually dissipates when removed. A relatively recently-deceased being can be revived by infusing an imprinted mask with sufficient amounts of energy, although this process is almost unheard of and is considered by most to be no more than a legend.
In the Doronai Nui
In game terms, a being’s ability to activate a mask power is rationalized as a Kanohi Charge (often abbreviated as KC). Each Kanohi Charge represents a being’s ability to focus on activating a Kanohi mask and controlling the ability therein. Certain masks may allow you to spend additional KC to increase the duration of their power; in most cases (unless noted otherwise), for each additional KC you spend, add the length of the original duration to the total duration. The number of Kanohi Charges available to any given being is determined by their total bonus in the Use Kanohi skill. Some Kanohi additionally require Action Points (AP) to activate.
In order to activate a Kanohi mask, your character’s Species must have the Kanohi Wielder ability (certain Species are only capable of using Noble Kanohi - see the Species Index for specific information), and you must spend one or more Kanohi Charges to activate your mask power. Depending on the mask, its powers may be instantaneous (e.g. the Kualsi, which allows its wearer to teleport to a location in their line of sight) or remain active at a low level until either a set amount of time has passed or they are deactivated by the user.
When activating a Kanohi, you may not spend more Kanohi Charges in a single activation than your Proficiency Bonus - this is your Expenditure Limit. Any Charges required to activate the Kanohi are included in this count, along with any extra Charges for increased duration or effect. Unless an increased or altered effect for spending additional Kanohi Charges is specified in the mask’s description, spending additional Kanohi Charges when activating a mask only increases the power’s duration.
Some Kanohi powers require Kanohi Attack rolls, which are made with your Wisdom modifier. If you are Proficient in the Use Kanohi skill, you may add your Proficiency Bonus to any attack rolls made with a Kanohi. Some mask powers (as well as many other abilities) also require the user to maintain Focus and Concentration, or the effect will end. In order to maintain Focus, the wearer must succeed on a Focus skill check to Concentrate, with a DC determined by the scenario (see the Focus skill and Concentration description in the Rules Guide under the Terminology section for additional information). Many types of distractions can interrupt or break Focus, including the use of another ability, a separate activation of a Kanohi, the removal of a Kanohi, failing a Focus check after taking damage or being distracted, being knocked unconscious, or dying. Whenever you take damage while maintaining an ongoing effect that requires Focus, you must make a Focus check (DC 5 + damage taken); on a failure, you lose control of the power, causing it to immediately end. Certain ongoing powers (such as the Kanohi Artamu) are not subject to Concentration checks - these exceptions are noted in the description of the mask power, and the GM may add exceptions at their discretion. Additionally, whenever you activate a power while maintaining concentration on another power, you must make a Focus check (DC 20 + situation modifiers); on a failure you lose control of the maintained power, causing it to immediately end.
Kanohi powers use a unified Save DC system equal to [8 + PROF + X + Attribute Modifier]. When a Kanohi power requires a saving throw, it is listed as Save Type (DC + X Attribute). The numeric modifier in brackets is added to your Kanohi Save DC as the X value, while the listed Attribute is the Attribute Modifier that is added to the Save DC; if the Kanohi does not list an Attribute Score, you add the highest of your INT, WIS, or CHA modifiers. For example, if a Toa activates their Makoh, the DC is equal to 8 + 2 (their PROF) + 2 (the Kanohi modifier) + 3 (their WIS, as specified by the mask power).
