Spirit Sacrifice. A Level 75 Summoner ultimate skill. It wasn't just for spirit users, but it was the skill with the highest attack power across all Summoner skills. After this skill came out, countless Summoners started calculating the damage this skill could do and, from the current tests, Spirit Sacrifice seemed to be the second skill after the Assassin's Life-Risking Strike that could accomplish a One-Hit KO.
Of course, like Life-Risking Strike, wanting to successfully accomplish an OHKO was very troublesome.
