Tukor's Tentative Reprisal

Your spell bolsters your or one of your ally's defense, a shimmering, translucent force field visible to everybody appearing in front of the target, giving a +2 to their AC.

If the spell's target is attacked by a creature, that misses the target with its attack, the shimmering force field lashes out in a form that you visually flavour, dealing 1d6 force damage. The backlash's maximum range is 100 feet.

The effects last only until the start of your next turn and do not stack/work with any other spell that adds a bonus to the AC, spells increasing the base AC still work in conjunction with this spell (e.g. mage armour).

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the force field's damage increases by 1d6 per level.

At 4th, 6th and 8th level or higher the bonus to the AC increases by 1 each time respectively. (So the bonus at the 8th level is +5)
