My D&D group decided to attack a group of vampires and I ended up getting bitten and becoming a vampire.
I was playing as a level 15 halfling rogue and had 12 hp left. I was trying to make some distance between me and the vampires. Unfortunately, two more vampires entered the room through a door I ended my turn next to. One of them hit me and the other grappled and bit me... taking me down to 0 hp. I was then used as a health station to for the vampires to keep the fight going.
The DM imposed a houserule related to death: Each turn after being reduced to 0 hp, you lose 1 more hp. Upon reaching -10 hp, you die. I was given a proper funeral and then I rose from a coffin the next night.
Apparently, there aren't any clerics that can cure me.
Player characters transformed into vampire spawn gain their traits, including Sunlight Hypersensitivity:
Sunlight Hypersensitivity. The vampire takes 20 radiant damage when it starts its turn in sunlight. While in sunlight, it has disadvantage on attack rolls and ability checks.
Is there a way to diminish the damage taken from sunlight (i.e. a spell, magic armor, etc.)?
