I am a Stamina Hybrid Templar DPS and Tank and when running my DPS CP 3200 I have Approx 20k Health 13k Magicka and 32k Stamina and I am having Zero Sustain issues and PLENTY of Magicka to go around. (With 5 to 6 Magicka abilities on my bar)
So, I am Running
Candied Jester's Coins (Flour,Coffee,Imp Stool and Bervez Juice) which is awesome. Approx 4600 Stamina and 459 Magicka Recovery (Enormous)
With a Stamina - Health Potion. Cheap ingredients Blue Entoloma - Dragonthorn and Mountain Flower.....
Final Piece and Truly not needed and the DPS drop is miniscule. I use Radiant Glory for Magicka restore and Health restore in Execute and a Fantastic Bonus too Boot!
I recommend you try it out if you just want to save Gold or struggling with the price of columbine. It's Truly amazing.
Cheers!
