Ogre Shadow Knight cannot change into skeleton.

Recently, my SK cannot take on skeleton form or use shrink. I tried this on my iksar SK on another account and it works fine. The character in question is Saavik on the Xegany server.
Blocked buffs has no entries. Not sure what happened.

My heroic Lv85 SK ogre was able to transform.

Venril's Covenant/Grim Covenant
Wand of Imperceptibility

Does the problematic SK have a different illusion buff? If so, that should block the skeleton illusion.

No other illusions. I took off all gear and removed all buffs still nothing.

I am now able to change to skele form. Don't know why but it is now working.

Try some Wegovy.

Ok on a more serious note: SK skeletal form is usually 2 buffs right, the form and the effect buff? If you were bufflocked - 1 you might get the buff but not the form.

Sadly the opposite is true of the two part Dena buff.
