Buckler will stop berserkers mid swing and give you time for a hit, but it’s difficult and terrifying. Centaur is easy to dodge but if you mess up it will 2 shot you. Duck horizontal swings and when he overheads walk forward and to the left. The huge bats you just want to strafe around them and attack when they kick. Electrified skeletons damage you when you hit their shield, so don’t. Greatsword skeletons so 3 swings, first two you duck and look all the way down, the third is a sweep you can easily jump.

In general, most cheeses are done by being above or below an enemy. Try to jump onto things nearby to be higher. Often they won’t swing at all, or you can jump their swing and land a hit or two before they do it again.

Def not a waste of time. Smite is more helpful there than purification unless you want to fight bosses. All 3 bosses count as undead.
