Before the maintenance world tree silences enemies inside it’s radius, it also prohibits them from normal attacking.
Now mobs inside the world tree can attack AND cast skills, it literally does nothing now.

You can see that mobs can now attack and cast skills (ice pike).
I would also like to restate the bug about laima still not being able to reduce non-overheat skill cooldowns without the use of hotkey methods (weapon swapping / equipment unequipping requipping) or placing a zemyna statue.
