Soooo my suggestion involves 3 Specific classes, the Vampire, Werewolf and Zombie (dont skin me alive hear me out 😭). Basically what im thinking is, that everytime its a specific night, one of the three classes get an enhanced buff

Basically:
Normal Night buffs the Zombie class with:
A speed bonus
Better Healing
Better Visibility at Night

Full Moon buffs the Werewolf class with:
2x -> 3x Stats
Better Visibility at Night

Blood Moon buffs the Vampire class with:
More walk and sprint speed
Higher Melee dmg
Vampire Knife heals for 10 instead of 7.5 (full charge)
Better Visibility at Night (or..... idk)

yep..... thats all c:
(hope no one skins me alive after reading all this......😭)
