Tells are out of character.
Tells are Purely OOC communication for banter and discussing the odds of verk dying on the quest. They are not 'requests for help' or 'all clear'.' If you're in a PvP situation, or in a situation that might result in pvP, you are NOT allowed to use tells as this is metagaming PvP.
I will retire your PC faster than you will die to the DM kill button.
