Arcane Bolt

You create a glowing bolt of magical force the size of a large football and send it flying at a creature within range, making a spell attack. On a hit, the bolt deals 2d12 force damage to its target. The target must also make an intelligence saving throw against your spell save DC. On a failure the magic bolt then travels, bouncing from them to another creature of the casters choice within 30 feet of the target and the caster makes another spell attack. On a success the creature takes 2d8 force damage as the energy is absorbed into them, and there is no extra bolt. The bolt can jump up to three times. If there is only one creature, the bolt cannot jump and the creature instead immediately succeeds on the saving throw, but still taking that 2d8 extra damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d12 for each slot level above 1st. The extra damage at the end does not change or increase.

(this spell is a bit "all or nothing", but when it works it really swings! it's what you would hope for from a good spell!)
