Dragon Ogre Shaggoth converted to Pathfinder!

[Brolof]

Exactly what it says, I converted a Dragon Ogre Shaggoth to Pathfinder to use as a boss a while ago (Never got to use it sadly T_T). Opinions, Comments, or Concerns?

Special Abilities

Lightning Strike: Once per 1d6 rounds, the Dragon Ogre can call down a lightning strike as a full round action, dealing 5d8 electricity damage and blinding them for 1d3 rounds. A successful reflex saves halves the damage and negates the blind. (DC 20) This DC is Con based.

Stormbringer's Axe; This +3 Shocking Burst Greataxe that allows the wielder to use Control Weather once per day, but only for the purpose of summoning a storm or making an existing storm more severe.
