Animated Tile Chimera

If destroyed, the tile creature regains all its hit points and becomes active again in 24 hours unless at least half its tiles are collected and kept separate from the rest of the creature's tiles.

The chimera makes three attacks: one with its bite, one with its horns, and one with its claws. When its fire breath is available, it can use the breath in place of its bite or horns.

When targeted by a melee attack, the tile creature can take a reaction to turn its narrowest aspect toward the attacker. The attacker has disadvantage on the attack roll.
