Isabella is a channeling-dependent caster who ramps damage through uninterrupted spellcasting. Her normal attacks are replaced with targeted lightning that stacks bonus damage with each successful cast, but interruption resets the stacks entirely. Every few casts release additional lightning bolts that spread to other enemies. Her ultimate launches a barrage of arcane orbs that prioritize unhit targets, with each successive orb hitting harder than the last. A channeled energy drain steals energy from the nearest enemy and permanently strips their crit rating if completed. Passive casting speed bonuses accelerate the whole loop, and kills triggered by her ultimate terrify all surviving enemies. She punishes teams that can't interrupt her and snowballs harder the longer she's left alone.
