Happiest Mask

The Happiest Mask is a returning item in Risk of Rain 2.

When the holder kills an enemy, there is a 7% chance that a ghost of that enemy will spawn as an ally, with greatly increased attack strength. The chance for this to happen is affected by Luck.

The ghost inherits all behaviors of the original monster. The level of the ghost equals the "ambient" level of the run, not the player's level.

Ghosts do not take damage through any normal means; instead, their health drops by a fixed percentage every second. Each ghost normally lasts 30 seconds (+30s per stack), though this can be prolonged if they are healed.

Tips

 * Use to boost the attack speed and move speed of allied ghosts, making them even more stronger.
 * Since a ghost's lifespan is only limited by time, healing it can give the player a near-permanent and powerful ally. Ghosts can be healed by:
 * Collecting orbs or  fruits.
 * Being in the range of, , a Shrine of the Woods, , or an allied  (likely a ghost itself).
 * Having a sent to them. Since the Woodsprite heals the ghost for 1.5% of its max health per second, and the ghost loses 3.33% of its max health per second with 1 Happiest Mask, the Woodsprite will almost double the ghost's lifespan (and make it nearly immortal with 2 Happiest Masks).
 * Being in the Teleporter radius when a activates.

Trivia

 * A ghost is actually the original monster with three special hidden items equipped. One makes its health deplete over time; ghosts are awarded 30 of these per Happiest Mask the user has. The second makes it appear and behave like a ghost, so that it is invulnerable to normal damage and becomes transparent. The third boosts its damage; the ghost is supplied 150 of these.
 * Because the time a ghost lasts is tied only to a damage-over-time item it receives, it is possible that ghosts can survive indefinitely because of their healing ability.
