Is it intended the waves of Grimling attackers take forever to attack? Quest says to defend myself, and I'm standing around for 5 minutes trying to figure out if I'd done something wrong before the first 3 charged. Killed them and now standing around waiting for more. Could you make them come a bit quicker? (and preferably all 15 at once )
I just went into shiny hunter mode. But yeah, it takes forever. First time I walked around, killed a few grimlings to see if it updated (nope), and then turned my mind to shinys. After a particularly long wait, I got 3 groups at once and nearly died because my merc ran off to attack them and got killed before I noticed he was missing. LOL good times.
There should be MOAR quests to kill those little rascals. And yes they did take a long time to turn up.
You need to run around that area where all the grimlings are and they will trigger. Trigger points seem to be random but you can get several waves on you at once. Never tried to get all 15 at once but probably can be done.
