Forged Arcane Charge

Make a DC14 Arcana check using
craftsman's tools.
On a success, a spell slot that you have in reserve
is stored in the Charge
On a Fail, roll on the Hobgoblin's Table of Oops
On a Critical Success, roll twice on the table,
and choose one to access with this charge.
You may instead choose to give a charge to a
scholar to imbue with a spell you don't have
