Pros & Cons:
+ Very interactive for a totem build.
+ Fun resource management gimmick.
+ Should be fairly adaptable to Summon Holy Flame Totem.
+ You can start leveling key skills (Fireball and Spell Totem) early.
+ You actually get to build crit instead of just grabbing Elemental Overload.
+ Multiple starting class options, Ascendant and Heirophant are both just as viable, if not more so.
- Requires good management of Flask uptime.
- Fireballs sometimes have trouble hitting fast targets.
- Easy to run out of mana if you're not careful.
- Running out of mana flask charges can be potentially deadly.
Ascendancy:
Heirophant -> Chieftain -> Path of the Marauder or Path of the Templar
Bandits:
Kill 'em. Nothing is worth the 2 passive points.
Pantheon:
Solaris and Ryslatha are my go-to.
