Pyroconverger

- Requires Attunement
As an action, you can cause the pyroconverger to
project fire in a 10-ft. cone. Each creature in that
area must make a DC 13 Dex. Saving Throw,
taking 4d6 fire damage on a failed save, or half as
much damage on a successful one.
Each time you use the pyroconverger, roll a d10 &
add the number of times you have used it since
your last long rest. If the total is 11 or higher, the
pyroconverger malfunctions: you take 4d6 fire
damage, and you can't use it again until
