DMG is obvius, so Crit... but what about the others...?
FT for example... what does it mean?
And why Virgil prefers an FT 4 (+12) weap, to a DMG 1-8 (+12) FT: 4 weapon?

FT stands for Fatigue. Some weapons deal fatigue damage in addition to health damage. As for Virgil's preferences, all of your henchmen will always equip the the weapon with the highest damage score out of all the possible swords, axes, staves, and so forth that they are capable of using.

Interesting... though it seems incorrect... Virgil ignores a magic sword in his inventory that has a greater DMG value than his staff.. however, his staff deals way higher Fatige damage...
