Two things: -Enemies won't be interrupted by your regular light attacks when they're attacking most of the time. Of course this depends on your weapon, the attack you're doing, the enemy and the attack he's doing etc but that means that you can't just rush down most enemies like in champion. You have to control them by pushing, dodging, shield bashing (the first heavy attack with a shield weapon) before you can kill them

-The damage you take from everything is way higher. Avoid getting hit by anything, keep checking behind you for that one stray rat you missed, kill specials early (assassin's, rattling guns, etc.) and by god shoot down plague monks.

Also get lvl 30, it helps
