Hello, bit of advice needed from you more experienced tree-huggers.

So I'm leveling up a drood box to duo with my bsty. Currently its at level 65 with few of its post 60 spells. I'm wondering if I get it up past 70 if there are any of the 60-70 spells I should make it a point to get. I'm guessing the skin of the reptile spell would be one, are there any others?
thank you
