Dark Angelic Ring attack buff stacking?

Sorry if this has been answered before, but I wasn't able to find an answer.
From what I understand, the ring you are able to make using the jewel crafting system gives a 5 attack buff. (not as a passive attack boost)
Would that attack buff stack with Dragon Blood AND Beholder's Hex for Dark Knights?
I'm not too familiar with the mechanics of buff stacking so I'm quite confused.
I know this hasn't been released in gMS, but I was hoping some people would know the answer so I can prepare myself.
Thanks in advance.

The buff stacks with an attack potion and with Super Transform and Energy Charge.
I tried this buff with the Rage skill, and it stacks but.. when I have Rage and this buff on, it doesn’t stack with Energy Charge. But that’s alright. ^-^

After rereading this section over and over, I think the answer is yes. Spadow says that it stacks with ST and Energy Charge, both of which are smart buffs (I think that's the term). Rage is not, nor is Blood. If Rage, ST, and the buff stack together, then there shouldn't be much of a reason Blood, Hex, and the ring wouldn't stack.

Now if only they had the option to hide the effect the ring gives.

When I was reading that, I just replaced Rage with Blood and Energy Charge with Hex.
"I tried this buff with Blood, and it stacks but when I have Blood and this buff active, it doesn't stack with Hex."
So confusing @_@
Thanks anyway, I guess I'll figure it out when it comes to gMS
