Similar to my recent question on how to use Avatars, we have another cheater who joined our Official server and built an undermesh base while raiding others. I have submitted to Funcom and they said they will eventually address it but will take time.
In the meantime we are trying to hit them hard (at least distract them). We’ve used bombs on the buildings above the mesh (all empty btw - not even crafting stations, LOL). In addition we did use a Yog Avatar on the base (that heavy tentacle ground “smash” attack) and it appeared to have done some damage underneath the mesh (using hammer I could see multiple damage indicators underground). We are trying to farm another Yog but no luck getting the archpriest.
We do have other archpriests. Just curious your thoughts on whether Mitra or Set could be effective?
