The Host and RP were probably friends since they were Flipping around and Gesturing eachother.
I Invaded and the first thing they did was Running towards me and TRIED to slash me down (Katana and a (?) Longsword type weapon (?) ) but they did around 0,5 % Damage on my Max Health bar so i used a WoG to knock them back. Slashed at the host two times (Low poise), backstabed him (Dead)
and nearly killed the RP. The Host sent me a Message saying that i was a ''***''...
*Long Sigh*
