Hope it’s not just “increase def level of boss”
It's not.
will we be getting any mechanical hints before release? really just curious if there’s any entirely new pvm mechanics.
Quite a tough question.
It really depends what you mean by "mechanic". We haven't created any new ways to do an "action", an "action" being something like activating a prayer, attacking an npc, moving, eating, etc. So in that sense, no there's no new mechanics.
However I'd like to think we've created some bosses that do things that are quite a bit different and bosses that feel quite a bit different to what we've had before.
Only time will tell if you agree.
