Corrupted Spiders are large, quick mobs that can be dangerous if the player does not have the right tools. Their odd alienoid shape makes them stand out from other mobs and are the BlackDown variation of spiders.
Corrupted Spiders can climb walls and see through transparent block, like glass or leaves. They will thrash their arms around wildly to deal damage and jump to deal about 2 1/2 <3. They make down-pitched spider noises and will always attack in groups. When one is killed, the rest will flee, only to return about several minutes later. After killing a Corrupted Spider, they will drop 0-2 Corrupted Spider Eyes and 2-5 string.
Corrupted Spiders are found commonly in the fabled BlackDown in groups of three or four.
