Currently, warlock gear requires exclusively a warlock. This is an interesting design choice, but it can result in difficulty obtaining gear, especially in surface civilization.
I think it might help out a lot if the "Pacting" races can also make warlock gear. Namely, Imp, Raksasha, Vampire, Hag, Fey'ri (I hesitate to include them but they're the only real match for abyssal pact) , and any other future or current races that align well with one of the warlock pacts.
