I think the tatt prog is meant to be that way.

Sort of like a double edged sword sort of deal, if I had to guess. Baer never addressed it, and I never asked. It ends up getting me killed against Thokran in my final log too, which was quite unexpected. But thats the nature of high reward type things. There may be inherent risks as well.

I dont know about the erroding spells echo. I assume its some shaman thing. I dont play shamans.
