Festering Appendage

Festering Appendages are a type of summoned monster that are associated with Baal, the Lord of Destruction.

Diablo II
Festering Appendages appear as tendrils which spring from the ground to attack players. Each appendage has three fingers that can strike at players as they run towards Baal. Baal summons them during the final confrontation within The Worldstone Chamber. They will disappear after a set amount of time, but are usually hard to kill since they quickly vanish into the ground, though at times, they can be shattered using cold attacks such as Hurricane. Contrary to popular belief, they do not firmly root to the ground and players can knockback them.

There are five variations of them, and Baal spawns two different types depending on difficulty. The fifth variation is unused.

Diablo Immortal
Festering Appendages appear in Diablo Immortal. They are briefly encountered in Deckard Cain's workshop, and are summoned by Baal in his boss confrontation. They function identically to their form in Lord of Destruction.
