Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General One Man Army challenge

Just finished my 1-man army challenge, and it went very well!

I played an Elf Fire Mage. I started as 'Knight' so I could have Rage without a point in Warfare.
Using temporary gear that gave +1 to various skills, I was able to learn nearly every skill, but I mostly used the same 8/9 for every fight.

The stats I had going into the final fight:
Level 7
34 int, 18 memory, 1 Hydro, 1 Scoundrel, 7 Pyrokinetics. This gave me maximum fire spell and wanding damage.
Talents: Pawn, Warlord, Savage Sortilege (Spells can now crit!).
My main skills:
Tactical Retreat, Rage, Spontaneous Combustion, Bless, Teleportation, Impalement, Adrenaline, Fortify, and Armour of Frost.
Weapons were fire wand + shield.

I'd try to start every fight the same way. I'd pre-buff Fortify, Amour of Frost, and bedroll rested bonus.
This gave me a large amount of armor and magic armour to prevent getting CCd.
I'd then start either by teleporting the closest enemy far away or opening with Impalement, due to its long range.
When I'd get my turn I'd unequip my shield. The shield was only for extra physical armor before my first turn to prevent me getting knocked down etc. Unequiping it takes no action points and reduces the cost of wanding from 2 down to 1.
Next I'd pop Rage into Flesh Sacrifice, and if available, teleport 1 of the enemies on another, Impalement them, wand to set them on fire, and Combustion for the kills. Adrenaline would get thrown in if needed. Warlord would then go off to help me clean up or I'd Tactical Retreat to a more defensive position until my next turn. I didn't have to use stealth or flee, the run was very straightforward.
Early in the game I used Winter Blast to CC stronger/extra enemies, but pretty quickly I was too strong for this to be necessary.

I had a lot of fun, this was a pretty good build. My damage felt a bit weak for the final fight (the health of these enemies was much higher, and the boss drank a few potions for big heals), but I was able to AoE everyone gathered around the worm as they killed each other, and with retreat I was in no danger of getting caught and killed.

Tactical Retreat was my MVP skill. It made getting the ideal starting position for my fights easy, positioning was a breeze, staying out of range of enemies, accessing extra areas in any order, etc. It is a monster skill. At first I used the Scoundrel variant, which is virtually the same skill, but as I didn't stealth I swapped to Tactical Retreat after picking up a +1 Huntsman bow.
