I think it'd be a cool idea for a new class to be a vampire which have certain debuffs during the day (reduced hp recovery, or no debuff at all) and buff at nighttime (increased evasion, or unlimited sprint like hashashin has in the desert). 

The pre awakened abilities can use claws and fangs, punches and kicks and some dark magic or blood magic of some kind. They could have a grab that restores hp (sucking blood of course) which wouldn't be too OP seeing as other classes have many ways to heal. The awakening could potentially be more magic n spell based or even wield a sword made of magic of some sort similar to awakened nova. So succession could be more visceral with the claws and awakening can be more spell based. 

as for the gender I think the class can have a male and female version similar to musa and maewa or ninja and kuno or wizard and witch. Maybe even have one gender hand to hand based and the other magic based. 

but that's just me personally I think pearlabyss would do a good job with making this class. Who know ls maybe it could be a Halloween release??? 🤔🤔
