..Well shit that explains some stuff. Thanks. I've generally been boosting just power and sometimes defense. Should I be boosting other stats as well?
As a note, you can tell what stat units work off of by the icon next to STY in the troop type screen of the commander's stats. A sword means Power, a staff means Int. You can also learn what type the commander is on the third page in the attributes column. Notice for Demon Knights that they actually work off Int, but the commander works off Power. This is where the weapons that give 4 Power and 5 Int come in.
Power- One of the primary offense stats. Either this or Energy affects the completion time of Fortification.
Energy (Defense)- Physical Def stat. Appointing landlords high in this will enable towns to shrug off magic spells that lower Fortification and troop numbers cast on them.
Int- One of the primary offense stats. Also affects the completion time for Invest.
Psych- Magical Defense stat. Appointing landlords high in this will enable towns to shrug off magic spells that lower Market and sap SP cast on them.
Speed- Increases movement speed and frequency of attack. DOES NOT speed up the attack animation though.
Charm- Increases probability of recruiting prisoners and enemy commanders. Also helps the success rate of alliances (not that they're useful).
Luck- Increases probablility of finding something good on Search. Search Star Points, Caves and Towers with high luck characters for Event chests which contain troop/class change items and legendary weapons. The one you can find right away is the Holy Hammer at Malolo, a cave near Rudora. 11 Atk Holy Axe.
