Gas mask (XSP)

A gas mask is a protective mask worn to protect the face and lungs against toxic gases.

Differences in Types
In Serenth, there are Type-1, Type-2, and Type-3 gas masks.

Type-3 gas masks
Type-3 gas masks are enchanted to allow for an unlimited amount of air, in addition to allowing the wearer to breathe underwater.

In Lunar Shadow ZER0

 * Aidan Flamberge, Alexis Flamberge, Ilina (unconscious), Martel Aar, Shinica and a Lamentation Girl are all seen in gas masks at varying points in time.

In Phantasma Shade

 * The Dark Scarlet Night wears a gas mask. Since she uses sleeping gas when breaking into places (like the Filenia mansion in No Town, the mask keeps her from breathing in the gas.
 * Satine also wears a gas mask.

In Lunar Shadow

 * A black face-concealing gas mask is a part of the Dark Armour.

In Lunar Shadow X

 * Amariss Richters wears a grey gas mask.

In Apocalyptic Shadow

 * Several NPCs wear gas masks:
 * Most of these NPCs believe the apocalypse of Serenth involves toxic gases.
 * Some races require the gas masks to breathe, as oxygen is toxic to them; so far, one such character appears in Apocalyptic Shadow.

In Umbrageous Light

 * Dataverse-Kaguya Hadley wears a gas mask for reasons not yet clear.

Races and gas masks
Members of some races often wear gas masks for reasons.
 * It is not uncommon to see Jotunn or Valkyries wear gas masks, as even tear gas can poison them and nullify most Synchs and Taints.
 * Likewise, it isn't uncommon to see Erinysi wear gas masks to protect them from airborne allergens, as exposure to any allergens can neutralize most of their Core (or even destroy it).
 * At least one race is known to wear gas masks on planets with oxygen.

Uniforms
Gas masks may be worn as part of some uniforms.
 * Some school uniforms require gas masks to be worn for various reasons.
 * The Serenthan spy uniform worn by spies requires gas masks to be worn.

Trivia

 * If Serenity Horton wears a gas mask in Lunar Shadow when confronting Aidan Flamberge, it will trigger a bad ending.
