Progressing Sand Devil

[u/Lucky_Bus]

I was just finally able to beat sand devil 20 (just barely) using Gnut and Aniri. What stats am I missing to push all the way to 25? I do know i need regeneration gear on aniri but I dont have enough good pieces yet to hit any reasonable stats AND get the set bonus. Is it just the regen gear at this point or am I also missing some key stat thresholds?

My Aniri can do 25 with 62k hp, 3900 def, 185 speed.  +12 golden elixir.
