Help with my poison ritualist pet build

Trying to create a acid/poison pet build and this is what i’ve come up with so far:

The generel idea is to spam blightfiends, where i use the amulet to convert their phys to acid. Though with the rings i guess that may be a waste, though i’m not 100% sure on how conversion works in this game.

Any advice on how to proceed? My DA is god awful, i should probably switch devotions around. Capped res would be nice too.

I’d look at this thread for inspiration. This is pretty close to what I’d do myself.
