Accuracy questions.

[Krausus]

Not true. Missing one or two strikes from Chaos Thrust & following up with Feint > Disembowel will net more damage than if you land all strikes from Chaos Thrust.

If you miss something large like a Blindside/Blood For Blood Doomspike then yea, you lose damage (can be fixed with Hawk's Eye anyway).

I haven't done any thorough testing on accuracy to see if there's a good middleground though.

chaos thrust is obviously the exception since it is multi hit and you have a high chance of missing at least one and each individual attack is not so high adding on a feint/dis or better yet full/faint/dis if you are fast enough is icing on the cake.
