Self aware forest

It seems workable to me.
There is enough there to make it easily (IMO) useable and alterable by a GM.

Maybe drop a line or two of explanation as to why Necromancy is so specifically singled out for hatred.

Maybe its not able to detect that kind of energy except by negative awareness (IE I used to be able to feel that part of me, but now I realize it's just gone). Or Necromantic energy is particularly damaging (necromantic energy attacks cause double damage or something) or something that just isn't coming to mind.

It's spell list doesnt carry anything that is 'conflicting' with necromancy, nor does it seem to have any innate or obvious weakness to spells that come to mind. I totally get how a creature like this would focus on life energy but what about it makes it fight without control against necromancy.
