Bugged Unique Jarngreiper

Jarngreiper "Strength can satisfy attribute requirements for melee weapons and skills"

Tried to use Quarterstaff on warrior for a potential Three Dragons Coldstrike - fire ignite build.

The skills under quarterstaff cannot be carved from the skill gems (not enough dex)

Skills like vaulting impact, and ice strike are labelled as "Melee" and done with a melee weapon (staff). Am I missing something?

I can equip a quarterstaff without the Dex requirements

I think this interaction is bugged currently.
