ToME: the Tales of Maj'Eyal

I decided to try my hand a playing a Maia this time around. I had a couple of questions about aggravation. I'm assuming my stealth level means nothing so that I shouldn't even worry about that. Additionaly does aggravation stack? In other words if I wield a weapon that aggravates will I aggravate more or aggravate monsters futher away? Thanks in advance.

Stealth doesn't matter (unless you use possession or mimicry to become something other than a Maia).

Aggravation doesn't stack- you either have it or not.

That's as I thought, just wanted to make sure before wielding a weapon to make even more creatures attack. Thanks a ton!
