Darius
"Yes, he is. If I may introduce you, Rhokkan, this is Ryash Loriant, servant of Pelor. Ryash, this is Rhokkan, a strong troll warrior. Our little fellowship includes a woman, too. But I think she is scouting ahead.
One question for you, Ryash, may I use an invocation on you, that will protect you from most of my attacks, as well against mundane heat and cool temperature?"
On a yes, Darius will reach out and bestow Endure Exposure on Ryash.
