Sickening offensive and Undead

[Randall Tupper]

This seems like it shouldn't effect undead but I can find any info to support this. Help

[The Guy With A Face]

A lot of sickening effects require a fortitude save. Undead are immune to any ability that requires a fortitude save (unless the ability also affects objects or is harmless). Most things that cause creatures to be sickened won't work on undead, but a few might.

[Torbyne]

because the attack lacks a saving throw only things specifically immune to sickened will not be affected.
