"I recommend you try my method too though."
My first priority with this game is researching a hybrid method--better prostitutes via orc power-leveling.
Anywho, here's how I got 2 orcs and Daisy to clear a Bandit Fort on W:1, D: 5
MC: Orc, Fighter, Curious, 6 PHY 6 CHA
Starting Peon: Fighter, Curious, 6 PHY, 6 SEX, 6 WIT (WIT is mostly for +xp, but also lets the peon double as the party thief)
Dungeon order: Farmed Goblin Dens on days 1 and 2, started farming Bandit Dens on day 3, cleared one Bandit Fort on day 5. Relied heavily on shards and bandages from the shop + one turn spent resting.
And, yes, days 1 and 2 are RNG reliant--but not as much as you might think. Getting life shards from shrines goes a LONG way towards mitigating other RNG effects.
------
MC leveling order: Attendant, Archer, Berserker, Rogue, SEX 6 for speed boost
Peon leveling : Thief, Archer, Berserker, Rogue, Watchdog, Sadist, Worker
Daisy leveling: PHY 3, Rogue, Harlot, Succubus, Archer, True Pet
Additional skills: Berserker unlocks Earth Shatter--get that ASAP on the orcs for a huge spike in power. Don't go into Bandit Forts without Fire Cleave ; you'll want that for burning down Ballistae.

Both orcs have a base speed of 60; I found a Belled Collar that boosted the peon orc to speed 65.
MC and Peon start bandit fights with Earth Shatter. Two earth shatters kill most Bandit Fort foes outright (and sometimes one Earth Shatter clears the entire board). Healing becomes MUCH less of a problem when most of your enemies die before they can react.
Daisy is mostly there to leech xp and to stun the most dangerous remaining foe (if any) with Attract. Archer gives Daisy extra speed and lets her equip Basic Combat weapons; put the highest +hit chance weapon you can find on her.
