You can solo the game with one mage, let alone 4 of them. ^^

"do a lot of damage except cleric ofc but cleric can boos their AC and damage even further."
Cleric with inflict wounds is kinda insane, it's up to 40 dmg on 1 spell.

For mages -> mage armour( lasts whole day) + mirror image per combat. Problem solved.

Alt+ left click in the inventory on an item while the camp stash is opened transfers the item there. Make it a reality.
