Full support sedna has it.
1 heal
2 hw
3 save
4 heal 2
5 hw2 silence
6 mag precense
7 heal
i think i would save till 10, or get mabey pounce for the interrupt.
that means
10 silence 2 ,mag pres 2, and heal 4 leave this out if you want pounce.
For gear, get a mana helmet and nimoth for some armor/hp unbreakables are standard for me on any god, scalemail helps for even more armor and is only 400 it hink.
Favor, hmm i like cloak of the night, saves my life atleast 3 times each match. Combiend with that 550 helmet it gives ok mana.
Later lvls id focus on pounce and further ranks of silence/mag precense. Counter healing is nice if there generals have bisschops.
This build will work best with tankish other gods. Like beast (spit/ooze hybrid) oak (6 spirits/surge faith/pent) sedna ( this build), thats a scary team.
