Dendrite does absorb some of those hits. Kind of. The first two whack into his front and rebound in flashes of blue, though still with enough force to push the mage backwards, but the third strike in the same place as the chimera-inflicted gut wound sends spiderwebs through his invisible Mage Armor, accentuated by a spattering of blood. Dendrite coughs and shudders, clearly flagging.

Codi sees her chance. She might not have any more spells, but she still has this very nice gun, so she might as well use it. A spray of bullets aimed at Dendrite's legs force him to dance out of the way. Codi follows him as well as she can with the tip of the gun barrel juddering in front of her face from the recoil - only for it to suddenly go silent and still with one last, hollow click of the trigger.

Out of bullets. Codi snarls in annoyance and chucks the gun at him; this would probably be the better place for Catapult, but she's running on empty now, too. The rifle doesn't even make it close enough to force Dendrite to dodge while he refocuses on Donatello. Three strikes, practiced to the point of being near instinctive, come at him: One jab to the gut, one to his chest, a spin and a kick to his face.
