Playable Vampiric Lineage Rules (including, for ease of use, a summarised version of the official Dhampir lineage from Van Richten's Guide to Ravenloft)
13 Vampiric Feats in a structured feat selection tree.
1 Vampiric Rogue NPC statblock
2 Vampiric Non-Humanoid statblocks
Notes on use and possible quest hooks.
Sure, you’re a nice DM. You want to give your players what they want. But when what they want is to play “Something from the Monster Manual”, then that’s just not practical. Or is it?
DMs may allow Players to use this material to create a vampiric PC whose bloodsucking traits remain level and tier appropriate. Alternatively the structures suggested here can be used following the character generation rules to create interesting Vampire NPCs that meld existing class abilities and vampiric traits or to create lower or added on an ad hoc basis to existing enemy stat blocks. So DMs can create vampire with a range of CRs and fully realize their bizarre concept for a Vampiric Tressym, or the BBEG Rogue, Count Swashle Von Buckler (both presented here).
Our approach to playable monsters begins with the use of Tasha’s custom lineages, or the selection of the closest available official race or lineage choice, but we don’t stop there. We break down all of the cooler powers and features of the monster stat block and rebuild them as an optional feat tree. This lets players select the aspects of the monster they find most appealing as the character levels up. By making PCs pay for the cool bits using their ASI increases and carefully arranging the feat tree structures, the power level of the new monstrous PC is kept firmly in line with the rest of the party.
