Usually in RPG, a two handed weapon permit to hit several enemies with each hit, while a one handed permit only to hit one enemy per hit.. Is that the case in POE with two handed weapons ? Do they hit several enemies (or is it the job of the talent Hold the line : https://pillarsofete...m/Hold_the_Line )?
No two handed do not hit several enemies by default. There are abilities that hit multiple enemies. Melee barbarian get a default talent called carnage that does this. Hold the line is a defensive talent. it give your character another engagement slot so if an enemy breaks the engagement you get a free hit on them
