I know, I dont have the video anymore, my computer had a virus so I had to make a big clean up and delete a bunch of files. I would make another one but I can't. I can explain the strategy tho:
1. Apply [item]Solid Sharpening Stone[/item] to your weapons, the boss is immune to poison.
2. Cheap shot, vanish (2 free CP)
3. Open with Garrote, run to the wall on the side while FACING THE BOSS so that you can attack him while moving, but don't use your Sssssssss key, just jump on the side.
4. Pop Evasion
5. Spam SS, eviscerate at 5 CP, repeat until you're low on HP...
6. Pop sprint, run to the other side of the room, make sure you dont loose aggro, use a [item]Heavy Runecloth Bandage[/item]
7. Spam SS, eviscerate at 5 CP, repeat until you're low on HP...
8. Pop Lifeblood
9. Spam SS, eviscerate at 5 CP, repeat until you're low on HP...
10. Pop AGM
11. The boss should be dead now (Sometimes AGM isnt necessery)
12. Loot
GZ! You're now much much much better than RC-ST!
