Grigor, human cleric
Grigor notes Megiddo's action and isn't sure if he should be amused or annoyed.
"Heh, the old ligh arrow trick, eh? Too bad arrows don't stick to stone walls. So, unless I make that one count... "
But then he decides to go with amusement. Life is to short to waste it with being annoyed. One of the central tenets of Olidamarra's teachings after all.
"Well, thanks for casting. Saves me a prayer. Could staunch a bleeding after all." he says to Megiddo with a smile. And dutyfully notches that arrow. Just in case.
