On the first days, I was once summoned as a purple phantom but I disguised myself as a white one, the host was suspicious at first (maybe he auto-aimed me after killing the mobs for mistake, i dont know) because he never stopped looking at me , but I helped him through the zone all the way (even though he never lighted the bonfires, casul maybe) and gained his trust until we arrived to the boss, he had no estus left (he even did the animation to show me) so he tried to kick me out (I guess he wanted to go to the bonfire or something, he was literally one-hit from a torch to die) and he couldn't (purple phantom, not white one) so being the jolly cooperation phantom I am I left so he wouldn't loose all those souls in the final area since he hadn't lighted any bonfire on the way. [spoiler]nah, I killed the poor bastard then and there and did the "well, what is it" 2.0 emote, ah... Nothing like killing some casuls in their own world and leaving them like "wtf?"[/spoiler] I -blam!-ng love dark souls.
