21 Blast or Stun Mastery

Mutherpineappleing Energy Blast. Stun Mastery is situational; it is ONLY worth using on Goby Houses during 3rd job, and to power up Barrage in 4th job. Energy Blast works everywhere, and is grossly overpowered.

And no, 3 is NOT the magic number you should stop at. If it were, Dragon Strike would not hit 6 targets, and Energy Blast would not hit 4 targets.

This is putting aside the 114% damage boost from level 11-30.
