I love Eureka, but honestly the spawnrate of Penthesilea for example, which is needed for the Relic Weapon, ruins the whole thing for me. It can take like 6 hours until she respawns and if you are unlucky and rejoin it can also happen that you end up on a new instance where she just has been killed just recently and you don't see her for days. And if you work etc and only have 2-3 hours a day to play anyway its so frustrating because you may only see her once in a week if you are unlucky.
