Damn, the bandit fortress escape mission was fun. Managed to kill all the enemies despite their force being overwhelming. Playing on the difficulty that has permadeath (Veteran I think) and trying to keep all my chars alive.
Moved all my characters up north to the river, placed the bridge with the engineer. Made it three tiles wide to allow all the escaping characters to pull out in their first turn, then placed a trap with Sabrina on one of the bridge tiles.
Then I pulled everyone except the crossbowwoman, Sabrina and that floating creature who can heal to the west to face the enemies coming from there.
Crossbow chick used her exploding arrows skill to destroy the bridge I had built, completely blocking half the enemy force from following me.
Ice mage girl used ice armor on my melee frontliners to make them resilient in the west.
When the enemy lowered their drawbridge, I held the front with Sabrina and her traps, while also destroying that bridge with the crossbow chick. Only three enemies managed to get across before I destroyed enough tiles to make it impassable.
So then I was free to mop up the enemies in the west, while also shooting down enemy archers across the river with my own archers, backed up by healers and ice mage armor boost.
Built a new bridge in the west to move up and deal with the enemies on the northern side. Managed to pick them off nicely one by one.
In the end, I managed to kill every single enemy... except Fera. That cunt was still standing at the entrance of the fortress, waiting for anyone to come close enough.
So I reconstructed the central bridge, buffed Lord Dakiri or whatever the bronze golem is called with an ice armor spell after healing him up to max HP, then sent him onto the bridge just close enough to trigger Fera to come out and attack.
She shaved off half his HP in one strike, so I retreated him away from the bridge, placed an explosive charge with the engineer, and had the fire mage toss a fireball at it...
Boom. Fera takes a lot of damage, the bridge explodes and she falls into the water, and in that state I could easily pick her off with my ranged units.
Fucking excellent fight. 10/10
