In the unit creation screen i noticed set items like the bandit and scout stuff
This got me thinking of various set items and how they could provide bonuses to the unit here are a few i thought of
Ranger: Bow and hide armor can move through forests without hinderance and can retret like a fast unit while in a forest
Palidian: Sword and sheild, plate armor. Can cast certain healing spells and has a bonus to fighting death magic creatures. (can be mounted or unmounted)
Fire mage: staff and robe can be used as an alillary unit with magic fireballs
Trition: Spear and leather jerkin. Can be like a marine unit and attack from a ship
Monk: Staff and robe. can spread religion and fight.
Necromancer: Staff and robe. can rez dead units after a battle to be basic skeltons.
Valkirie: Spear and plate. gives a moral boost to certain religions
these are just some ideas that i have had
