How does one get involved in behests? I keep hearing about them, but have never stumbled upon the NPC(s).
I did this once at Camp Skull Valley. There was this NPC standing around that I hadn't noticed before and my party and I talked to him. He said Behest was starting in a few minutes and a max of 15 people could sign up (in a party or alone but only 15 total). You need to kill a bunch of monsters around the valley and you have a timelimit like Guildleves. We weren't able to kill the last mob and we were the only people on the behest so we failed. Haven't seen one since.
I'm interested in knowing more about it though like if others on the behest could attack the mobs with you even if they aren't in your party. I know that people, even if they are in your party, couldn't attack the mobs if they didn't accept the behest at the camp.
