Forcer

You have an advanced understanding of force damage, creating a unique link between things of force and yourself. You gain the following benefits:

• You gain resistance to force damage.
• Whenever you deal force damage to a creature who is vulnerable to force damage, the force damage you deal is tripled instead of doubled.
• Whenever you make a damage roll, you can choose to add an additional 1d4 force damage. You can do this a number of times equal to your proficiency bonus per long rest. The extra force damage you can deal increases at higher levels: 1d6 at 8th, 1d8 at 12th, 1d10 at 16th, and 1d12 at 19th.
• You can cast magic missile at its lowest level without requiring material components a number of times equal to your proficiency bonus per long rest.
• At 12th level, you can cast wall of force at its lowest level without requiring material components once per long rest.
