Yoooo, rly in doubt between this trio, who can help me more going deeper in the game? Explain pls, may god be with u all 
Monsters here
I’d say Stormloch because sleep is the best pve strategy, then Santistag
Storm -> stag.
So, i’ll do Storm, after stag before tiamazus?
Stormloch first, then stag, then tiamazus.
First storm. Believe me, its a blessing if storm has HG. In my old acc i had shadow and it was helpfully to evolve le my shadow for HG (Hold Ground).
