Is the vanquisher's seal worth getting and using

[boolean]

Thinking about using a fisty boi build if it isn't total trash.
Does RoB work with vanquisher's?
Is caestus better?
Best stats to get best scaling?

I mean it IS the hardest hitting fisticuff, at least unbuffed. The damage order is Vanquishers > Caestus > Bone Fist. But the poise damage is the other way around and the bare fist poise damage is completely garbage, the Stone Ring won't make miracles happen. Also, the bare fist powerstance has a slower attack animation than 2x caestus or 1x caestus 1x fist.
The Str and Dex scaling is pretty good actually so you want 40 in each. (edit: well, according to your wording you'd actually need 99 in each for the best damage ;))(edit#2 sorry, confused its scaling with the bone fist. The Dex scaling is actually bad but the Str scaling is quite good. I edited way too often btw)

Due to the slow double fist animation 2 caestus or 1 caestus 1 fist is arguably better, even if it's a bit weaker (dps wise it should be better though, also that caestus is buffable and the fist isn't).

edit: and yeah, rob works. flynns too, before you ask that aswell.

If we're talking PvE, it's really overpowered. It's a fast, big strike damage weapon, that will never break and doesn't need any upgrades and you can get it super early. But the short range can get annoying. I'm 100% sure Flynn's works, so RoB should as well.

It has the best scaling with STR. Just pump VIG, STR and some ADP and start fisting some fools.

In PvP, it's like any other fist weapon - mediocre. Powerstanced L1 is the only good attack, but the range is just awful and alot of people will poise through it. I'd imagine you could do some great bullying early game with it, though, especially with the rollpunch-glitch advanced PvP-technique.

Edit: Typing is hard.

Thanks for the feedback, guys. So a buffed caestus/bone fist and vanquisher's is actually decent? Not a waste of a ring slot? Sounds like it'd still be useful even when it only applies to one hand
