I'm not an asmo, I'm just a dark skinned elyos
Asmodian spirit masters summon magma spirit, which is the giant devil looking ones
Elyos summon tempest, which is the blue one in the picture
Honestly, asmo SMs have cooler skills, but their character designs are too ugly for me to get in to
Pic related, asmo SM

is it worth playing?

Given the EU version is under Gameforge, the shop is well known for going p2w
and i doubt NA version would be going dandy as an european.

Asmo for life.

I prefer the looks of Asmo over Elyos
