So I need 3x morninglord and 3x FVS past lives to complete this Warlock project. So a morninglord FVS makes sense.

I have TF mats and mainly caster gear, all the orchard gear.

This will only be played from lvl 25-28.

Ideas on splits ??

10 fvs/9 bard/1 cleric swash main stat charisma with ameliorating strike, divine might and charisma to damage.

Take Frozen Fury from Warchanter too if you can afford it.

Actually a simple pure fvs sun elf in EA can be pretty powerful and fun, especially if you have enough pots to go full nuke.
You'll have some free SLA's and a bunch more single target spells you can easily chain.

You end up with lots of pretty powerful light based single and "lightning" light spells (that can hit multiple mobs in a line) as well as energy burst, a light version of energy burst (with 20 sec cd from EA) and hell ball at 26. Since you'll be playing from 25-28 you'll have all your goodies very fast. Wisdom based with gear can also get you a well working sound burst sla for easy mass helpless mobs (depending on difficulty of the content you'll be doing).

Check out Sestra build thread for the archived fvs version and some videos of it in action on his channel.
