Imagine four people having this ring in one game, weeeeeeeeh!

I recently purchased one and experimented while using my GF gear. The results were very random. Prior to engaging targets, I would let them hit me first. I never got any spawns from those engagements. I did get spawns in the middle of elite battles but it would sometimes be too difficult to chase the bastard down (frozen/jailer/firechain/sand wasp no thanks). Lastly, I sat for 5 minutes under one of those cleavers in the butcher dungeon hallways that constantly chop chop chop but no goblin spawned.

Sold it.

TLDR: Returns were too random and reduced overall farming time.

i also bought one, and i found the results pretty constant.... i mean for a full act 3 run, i would always have 5-6 goblins

not sure if its really worth it, but heck this is fun! fighting a goblim midway trough a ghom fight.... way to add a challenge
