Get lesser rod of extend ASAP to use Extend Rod + Snowball to do some damage early on. If You don't like that combo use Magic Missile instead

Comment:
Boneshaker is ok, but try to use the slots mostly for Extended True Strike, to have a decent number of Snowballs. Extend + True Strike is OP as it make True strike last for 4 Turns - the one You casted it in and 3 extra ones where You cast Snowball.

Add displacement to Your spells to make You a decent buffer to team members. Extend Sense Vitals + Extend True Strike + Scorching Ray now will do most damage You can.

Comment:
Waves of Exostion is one of the best debuffs in the game. It works on bosses, doesn't have a save option, is infinite and an AOE. Unless You are fighting undead / ghosts / elementals remember to cast it at start of the fight.

• Create Undead
  
• (Bloodline Free Spell) Finger of Death

Comment:
Creat Undead give You a decent summon but more of a flavour spell then critial one. Finger of Death with specialisation when lands does solid damage. With cloak of Sold Soul You should be getting those cast to land. I only recomend to use it on weak characters <400 hp, cause other way it is better to debuff them with Enervation.
On this Level You also get Incorporeal Form, that makes You a monster for 15 rounds per day. It makes You immune or very resistant to many attacks.

Comment:
Greater Angelic Aspect gives a lot of survibility, so should be up all time.
Improved Critical( Ray ) gives us a doubled chance to get a critical when casting enervation and the sweet chance to hit with 6 x 2 negative levels.
