Powder Mage WCX

You have combined magical power and gunpowder chemistry, which grants you the following benefits:

• You gain proficiency with the handgonne and arquebus, which you can use as a spellcasting focus.
• When you roll damage for a spell that deals fire or thunder damage, you can expend 1 charge of powder on your person to roll one additional damage die for that fire or thunder damage roll and add it to the total.
• You can magically sense containers and items filled with gunpowder within 120 feet of you. You can use an action to cause one such item to discharge or explode, as if it had taken fire or lightning damage.
