I thought you could do before iniative talk or some such posts. But considering Tarennar had readied action so his goes first and now I am waiting his charisma check so I can roll does he get control of the drow sorceress. Anyways the aura what the woman has is unlimited distance wise. Anyway if you plan knowingly do physical harm towards her in any fashion, you need roll that will save to do so. May you try hit with melee attack or shoot with a area effect spell from across globe.<br/><br/>However, key factor is awareness; if devil would sit on city which is about to get nuked and the sorcerer who does the nuking has not seen her nor aware of her, then aura does not work ofc. But otherwise Brand of Nessus is very powerful ability.
