Blood Tap

The following spell name is directly taken from Blizzard, but I owe nothing related to World of Warcraft nor Blizzard. I merely wish to bring the spell to the masses. All rights go to Blizzard Entertainment.

Creator note: This spell might feel extremely powerful, and probably is, so make sure to consult your DM before use. I made it with the Death Knights from the World of Warcraft universe in mind, therefor making it powerful.    

You tap into necrotic energy, converting 1 Hit Dice into a melee, ranged or spell damage dice for 1 minute.

At Higher Levels. Increasing the hit dice conversion to damage dice by 1 when cast as a 4th and 5th level spell slot.
