Aspect Skulk

From AoCWiki

-5%/7%/12% Hate Modifier. Also, ~113/.../198 Health debuff

Apparently the health debuff doesn't scale with level and so becomes negligible at Lvl80.

This is a Raid feat. Useless feat for Solo PvE.

It's an Aspect and only one Aspect can be buffed at any one time.

5s cooldown to activate/deactivate.

You can have Aspect A running, and provided it has been running for more than 5s, you can click Aspect B which will instantly turn off Aspect A and instantly turn on Aspect B.
