I didn't mean it as to take more than one attribute, I meant 'sharp' as the same term and included it to be consise. I added 'durable' because you said they should be adjectives, but put endurance too so to be clear as to what 'durable' had meant in context. I'll edit that out. (Please know I'm not trying to be defensive, I just wanted to explain my thinking because I promise I'm not just trying to cram as much power into her as I can. )
I'll definitely take the combat style out, especially because I had been worried about that in the first place. I dont mean for her to be a skillful fighter with it, more of a way to explain her staff's existance without giving away her magehood. 
I had figured there would be elephants similar to Indian or Asian elephants in the Brecilian Forest, which live in environments with tigers and wolves in Chinese forests, and figured both places would be moderate forests that got quite cold in the winter. I'll change the summons though, because that seems to be the easiest way to go. Too lazy to write up a backstory for my elephant lol. xD And again, I had planned on the spells being rites, but I'll put that in their description.
