[@PaulHaynek] - There are a couple things I'll argue in her defense.

Firstly as far as toughness goes she's fairly strong but her flesh is no tougher than most light elves. She's far easier to put together but depending on the damage sustained that can be made quite a bit harder. I've put a high resistance to dark spells and the ability to shirk certain types of curses but all other forms of magic work just as intended on her. By herself she's a powerhouse physically but her range and especially her speed are both lacking. Her attacks tend to be big single hit strikes while she makes little effort in dodging, usually opting to sustain blows in favor of a more aggressive attack.

Secondly while she is definitely more powerful than Leomund who quite frankly sucks when he's left alone they do make a potent team. This said she is not a student at the academy so plots that exclude outsiders will typically leave her uninvolved. She is by large a secondary character so her involvement will be largely circumstantial, especially for the tournament arc where her role will be quite passive indeed. When she is involved as a team they are quite powerful but Leomund will always be the weak link in the duo. Taking him out makes Gangraena much easier to fight as it deprives her of his support magic.

If needed I can remove the resistance to dark spells to give her a bit more magic vulnerability since she lacks the ability to cast spells herself. If you have any other suggestions regarding changes I'll definitely be watching out for input.
