How to get "Fire From The Earth" achievement while at a party?

Question

You need to kill 50 creatures that come with volcano eruption, but if you're at a party with another player(s), does it count if you only deal damage or you need to frag the creature?

Answer 1

Most of achievements involving killings monster just need some participation, I did before the  achievement helping a higher lvl to kill them and without been in party,   also the ones from demon war   was counting even if someone out of party had the frag, so it should work in same way is fine if you kill them with a party
