Spell Hunter

Your spells are tools to hunt down and eliminate threats as you have become a master of arcane combat. You gain the following benefits:

• Whenever you kill a creature with a spell, you may cast a cantrip you have prepared as a bonus action, rather than an action.
• Before you make an attack with a spell attack, you can choose to take a penalty to the attack roll up to your proficiency modifier. If the attack hits, you add damage to the attack equal to double what you reduced the attack roll by (prof. mod. x2).
