Pact of the Brand

Your patron marks your body with a symbol or feature indicative of their influence, called a Pact Mark, a vestige of their influence used to store and channel arcane power. Your mark is a symbol, like a tattoo or a blemish, or a physical feature, such as a unique eye or a wound, and cannot be removed unless the body part it is on is also removed. Your mark, and by extension your body, counts as an arcane focus for your warlock spells.

Whenever you expend a warlock spell slot, your mark gains a charge, to a maximum amount equal to your warlock spell slot level. You can use your mark to cast a spell you know, expending a number of charges equal to the level you cast the spell at. Your mark loses any charges when you complete a long rest, and you cannot gain more charges than half your warlock level (rounded up) per long rest.

If you lose your mark, you can perform a 1-hour ritual to entreat your patron to give you another in a new location. This ritual can be performed during a short or long rest, and it destroys the previous mark.
