|These achievements should be fairly easy to pull off. If you need help, here are a few places you can get them. Getting hit stops your combo, so don't get too greedy and dodge accordingly.|
1. When you reach the part in the story where you go underneath the mansion, there is a room with a massive amount of shades, at the beginning of Underground Facility: B2. Equip your weakest 1 handed sword and go at it, dodging when needed. If you get hit, die and try again.
2. On your second or third playthrough on your way to the Shadowlord, you should be able to kill the 'reviving pig' in 20 hits or so. Spam your sword and you should be able to kill him while he is reviving, before he hits you. Your weapon attacks faster the higher combo you have, so once you get the first 20-30 hits locked, you should be set.
