Warlock's Cursed Blessing

Summoning additional power from your Patron Being, some of your Cantrips increase in power, but there is a price to pay...

This spell can be cast once per long rest. When you cast this spell, every time you cast a Cantrip the spell Warlock's Cursed Blessing's power takes on 1 of 2 forms;

-If the Cantrip becomes more powerful as you level up (Chill-Touch for example), you get up to an additional 1D4+1 damage dice, choosing up to the rolled amount. Be sure to note down all the Additional dice gained this way, NOT the dice normally provided by the Cantrip or those that weren't used due to choosing a lower number, these points are needed later.

-If the Cantrip gains additional shots as it levels up (Eldrich-Blast for example), you gain up to an additional 1D4+1 shots, choosing up to the rolled amount. Be sure to note down all the Additional shots gained this way, NOT the dice normally provided by the Cantrip or those that weren't used due to choosing a lower number, these points are needed later.

Once the spell times out, tally up all the points earned and take a Charisma Save. On a failed save, you take all these points as damage directly to your Hit Points, while a passed save delivers half the damage.
