back stab freezes character
There’s basilisk venom that will prevent everything except stun breakers from working, which locks you in place. You can also become chilled from sigils or venoms, immobilized so you can’t move without lightning flash or removing conditions. I’m distracted right now so idk if I missed something. Also, it is possible to become stuck and that requires something like rid the lightning or typing an emote like /sit to become unstuck, it may be related to one of those wearing off and getting you stuck in the terrain, this last issue affects everyone.
