Your Favorite Player to Player Interaction?

Now most of the time player interaction in this game is pretty straight forward. Summon, kill boss, wave, done. Invade, rek face, shrug, done.

But sometimes, something totally different happens. I like to encourage this whenever possible, because we have full control to influence our own experience of the game.

I got summoned to this world in Heide's in the vanilla PC version to what looked like a 3 man sunbro gank. But then 2 of them bowed, used chameleon and backed away. I fought the sunbro, and then the second guy came out of chameleon, we fought, and after that the host left chameleon, dropped some endgame loot and ended up killing me.

This felt like a mini boss fight, and I love that the experience was created by other players.

What about you guys?
