So i was just lvling a new char and chilling in org i just got out of a dungeon and i am next to the bank sorta where the org thief spawns, but anyway i had just lvled up and got a new ablity so i went to test it on the thief but i had went to repair on my mammoth mount and i used a attack to dismount and get the mob out of stealth so i could test on it but for some reason it went and one shot for 4.6k as melee attack to a 18 monk (1.8k hp btw) and i was very confused so i did some bug testing and found out that if u have a low lvl char prob around lvl 30 or below and u get on any mount that has a npc or passenger seat it will one shot you. I have proof of this DM if u really would like to see and dont believe me.
