With Bokor2, you can always use Bwa, Hexing, Effigy, Cure and also Heal. But that is not all of them, you need to use Divine Might, Safety Zone, Fade, Samediveve, Zombify, Tet Mamak La and some time Deprotected Zone too. So don’t need to worry about the rotation.
About Krivis1, you should pick Bokor3. Learn how to use Damballa is not difficult. You can summon and blow almost every zombies between your cooldown on Heal, so those zombies will not eat your Heal. I also saw some people do C2>Bokor2>Diev1 instead. I don’t know they want to use the cooldown reduction for what but if you don’t go Bokor3, Diev1 should be better than Krivis1.
For rank 6, you have to pick Druid1, Pardoner1, Miko or Oracle1.
I think Druid is the weakest one because Druid should be a least Druid2 to be good.
Pardoner1 can increase Incineration duration but if you do PD2, the duration will long enough at level 10 and in the future, there will be the level 15 too, so it will be fine without Pardoner1.
For the others, I like Miko the most. Miko have a good damage skill which can hit flying targets. Think about why many people want it, it must have some good stuffs.
