I'm slowly working on finishing my guides. x-X It'll be harder now that I'm retired.
1. I strongly suggest go for AP. You can probably get enough HV from DM to ohko most monsters with Volley Kick (if you're using VK). Personally, I used GS+GLS combo with pure AP gears and would be if I were still playing. If you're using VK, go for one decent HV equipment and play with how much you need. If not, go for the AP.
2. Tut should be easy for an entertainer at level 60. I had no problem, I slapped on an HP shield to be safe and spammed VK.
