I've been having some fun at the forest with my assassin/troll build. I usually just try to waste their ganking time as much as possible instead of trying to kill them. with ring of fog and chameleon, it's so fun to annoy them and make them run around the forest for 15 minutes. I only attack if I get a good chance.
So, this is how I like to deal with gankers:
I was too lazy to edit the video, so it's quite long and there's not much action, so feel free to skip straight to 8:30.
At first, i was just entertaining myself by following them and watching what they're doing. Then, when I thought they saw me, i tried to get them follow me to the bridge near the catbear enemies, but suddenly the sunbro died and I decided to run to the stairs to prevent the host from summoning another phantom.
Well, surprisingly he was clearing the mobs by himself and he started chasing me. I didn't even try to hit him, i just wanted to annoy him a little bit more before finishing it.
-Gankers wasted over ten minutes of ganking time
-Host broke his covenant with alvina
It pleases me to know that the host must run all the way back to oswald and spent a great amount of souls for the absolution.
