*So title is wrong this build is for post enhancement change, not Update 18. I was confused.
1 Arti or Rogue/ 13 FVS/ 6 Sorc
All enhancments into FVS trees. Tier 4 Angel, Tier 5 Protector
All toughness + EmpH
Stats and level ups: All Con, rest of points in Int
Spells: Heal, Magic Missile, Chain Missiles, Blade Barrier
Twists: Renewal* or Energy Burst, Boulder Toss, Cocoon !Thx SealedInSong!
It heals, it has health out of the Kazoo, it does mana efficient damage regardless of mob elemental immunities, it has no save CC, it traps, it has UMD.
It has a higher universal spell power than a Sorc., force crit since Sorcs no longer have force crit, as well as universal crit from FVS line and FVS tankyness, and higher AC, since FVS simply has better enhancements.
Permanent blur, toughness, and knockdown when damaged with spells are just a bonus. FVS force caster level enhancements will allow you to cast MM as a lvl 9 spell at tier 4 Angel of Vengeance, and still max out the Protector tree.
So not only does it ignore elemental immunities and resistances in every raid end game, it is incredibly tanky and party boosting and friendly to boot. Tanky/DPS/UMD/Traps/Heals/CC/Buff
I'm going to be able to take a sorc based spell caster, power it by FVS enhancments, put it into a ranger epic destiny, and twist in supporting mage (or sorc), druid, and barbarian ED abilities, and add a single level of rogue or Arti, because, hey why not...I have to sink all my skill points somewhere.
If one really wanted, one could drop sorc to lvl 5-3 and use arcane augmentation items, like Twilight. This would allow evasion and higher level FVS spells, but you would lose chain missiles.
Now come on, someone, anyone tell me that the new enhancment paths don't support variety.
Edit: Apparently, if you use Shadar-Kai Assasin as an iconic character, you lose the ability to reincarnate, and gain racial wings + invisibility.
So this would be a pretty good Shadar-Kai build.
Edit: Added renewal as alternative twist. Healing EE on my druid made me realize that it would be necessary. At 5 mana it can "fill in" between MM spells, which will normally crit.
