Boss Damage stacks now?

Person in my alliance has two 30% boss lines on her knuckle.
She claims she hits 160k's in dojo and only 100k's on normal mobs.

I've asked for screenshot proof, hopefully it's forthcoming, but if anyone here has such a weapon and can test, it would be nice.

I thought it only stacked in Chaos from what I've read. Seems a bit fishy if you ask me.

Well, I've seen the screenshots, which she asked not to make public
Wouldn't prove anything anyway since she could have switched half her gear in between.
And doesn't really matter with Chaos so near.
Just suggesting that if anyone has a two-bossdamage weapon they were saving for Chaos, try it now and see what happens.

I tried it with a Dual Blader with Katara + Dagger w/ 30% boss and it didn't stack as of v97.3

ask her to take a SS of her dmg range in the attack window while attacking a boss.
