Yeah, that's pretty much all you have to do. Use sleeping potions wearing an Opo necklace at the beginning, get 100% tp. Run in and Berserk, Warcry, and all that other junk you get. Raging Rush, pop Icarus Wing, Raging Rush.
Well the warrior fight is an absolute joke (i did it easily at 66)
1. sleep yourself to 300% tp
2. Use Berserk, Aggressor, Mighty Strikes, Warcry
3. Use Raging Rush (I hit him with 2-3 regular hits first, but it isnt necessary)
4. Use Icarus Wing
5. Use Raging Rush again; you should get a Fragmentation SC that should be enough for the win if it isn't resisted
