After choosing the Tier 3 passive which gave weapons and abilities a chance to apply 50 scorch stacks, I was able to apply them to myself and my teammate. This ended up causing my client to desync with my teammate, preventing me from opening chests/ reviving my teammate, etc.. While holding my crafted Calus Mini tool with incandescent, I would randomly apply scorch stacks to myself and ignite myself. While in a Well of Radiance, I would randomly apply scorch stacks to myself and my teammate. If we stood in it for too long, my teammate's scorch stacks would reach 100 and his ignite would kill me. I believe the de-sync occurred because of the massive amount of scorch stacks I kept applying to myself while standing in my own Well of Radiance, but I haven't gotten to try and reproduce it again since it happened. While de-synced I was able to damage and kill my teammate with my weapons, and also apply scorch stacks to him with my Calus Mini Tool. The de-sync occurred a little before 8:57PM CST last night (to make it easier to find). Thanks for your time!
