Value of dual vamp weapons in general

Q9 dual vamp perf will ofc be the prenium item. It's the ratest base mod alomg with dual zeal. These are rly valuable depending on the skin.

Q10-13 will also be valuable but value degrades drastically compare to a q9

Yes 1 hand are usually more valuable as people prefer them so they can couple it with a grim cesta -50hp or what ever reduce hp to die faster. Back in the days it was used mostly in gvg ha to die before the rez timer and not be time killed.

Now a days people collect them mostly cause they are rare and also can be usefull in pve for what ever stuff

Double hand dual vamp are still valuable if perfect.

I mostly trash 14-1 even if few people buys them for dozen ectos again depends on skin

This hand axe is worth 10-20e max imo

To add on Blind’s answer, all one-hand dual vamp (axe sword) are usefull for pvp as a timekill switch.

Any req is worth keeping and sell to a pvp player.

Ask a base of 20e+ for it.

Else, they are wanted for collecting ends, and you can go back to What Blind said

Last note : if , by any chance you have dual vamp scyth or spear (dont know if any dropped during mauso bug), pricless item.

Just to add: it obviously also heavily depends on the skin.

If a certain skin is generally more demanded/rarer and more expensive than others (think of e.g. oni blade, zodiac sword, spiked club...) its dualvamp version worth is significantly higher than its worth with other perfect stats (+5e / 15^50) . And as stated above especially on q9 (and lower) this heavily increases as these reqs. are considered as perfect and thus most collectable.
