Mirrorback spider

The mirrorback spider is a spider that spawns in the second phase while fighting Araxxor on the top path. They may also spawn on the third phase if the player took the middle/bottom path while the top path was available or on phase four if players used the top path and skipped it. A mirrorback spider will also spawn for 10 seconds when a player with any Noxious weapon uses its special attack.

For the mirrorback spiders that Araxxor summons, any damage Araxxor would take (dreadnips, familiars, AoE attacks, direct attacks), will be fully reflected back onto the player. Damage inflicted on the spider will also hurt Araxxor for half the damage that the mirrorback spider took. Should the hit deal more then the health the spider has, damage reflected on Araxxor will be how much the hit would have done. If a player hits 12,000 on the spider (it would deal 3,000 to the spider), Araxxor will take 6,000 damage rather than 1,500.

For the mirrorback spider players summon, successful attacks against the user will reflect half of that damage back onto the attacker, and half onto the spider. The player summoned mirrorback spider cannot be attacked directly by other players.

Killing Araxxor with reflected damage from a mirrorback spider he summons is a requirement to unlock Gavin.

The mirrorback spider is likely based on the real-life mirror spider, which has reflective surfaces on its abdomen.

Trivia

 * There is currently a glitch while fighting Araxxi, and if she spawns a mirrorback spider, it may become stuck in the centre on the tiles she uses, and cannot be attacked by the player.
