So this sword is for one hand and two-handed at the same time.
I have used "hack" on two-hand dedicated paladin,
arm broken, he aren't gonna drop sword, and still may use their skills
based on two-hand dedication.

Nodisarm > hack.

unless it has changed.

Yup, also kotegaeshi.

I can confirm it's been that way at least 4 or 5 years and probably longer.

Because as gogonop I was dual wielding 2 no disarm weapons and kot and hack would still make me drop the offhand. It was fixed after that char but that wasn't 4 years ago.

Just sayin

I'm not positive but I believe it was fixed in Hunsobo's day.

Which two nodisarm weapons were you wielding?

Also if you remove one and try to rewield it with a broken wrist you can't - it is nodisarm, not canbewieldedanytime. That may not apply, though.

I would have sworn, probably based on reading logs, that while they wouldn't drop defiance due to kot, they wouldn't be able to use two-handed skills anymore. Is that what you are confirming is not the case? I think so, but the answer seemed a little ambiguous.
