oh and this is what i have so far

starting out in character creation take 1 geo, 1 warfare to take executioner talent

for initial stats pump INT, for skills take fortify, poison dart, fossil strike

Level 1: 13 INT, 1 Warfare, 1 Geomancer, Executioner
Level 2: 16 INT, 1 Poly
Level 3: 18 INT, 1 scoundrel, 13 Memory, Mnemonic
Level 4: 21 INT, 2 Poly - ready for medusa head
Level 5: 23 INT, 2 Geomancer

Hopefully i can update this further if work and life permit me to finish this build. I am on tactician too.

My skills are the earth and poison spells from geo tree. Adrenaline from scoundrel. MEDUSA from Poly obviously, really cool it shows up in fort joy. Battle stomp and battering do have their uses, especially if you have a dedicated physical damage teammate. I have ifan as a ranger and beast as a dual rouge. My fane is my support mage.
