Ah okay good to know! I just assumed it would be similar to the guardian spirit griffins, oh well my assa's pretty much dont get hit by debuffs anyways :)

Personally as a unit to use in the beginning I liked them a lot. I would always wait on their first action, so the enemy could run out a bit & then use their backstab. Then when the enemy got close I could use Murder & then immediately backstab again b/c of murder's special. I loved them as a burst damage unit.

I got rid of them as soon as I got demonesses though =)

I would use them more frequently if they are lvl 3 units. Being lvl 4 units and no buff means they will die quite a bit and 30 mana to resurrect them is just not worth it. That's why they start to phase out mid-late game.
