Author's notes

Beam carry. AP priority in beam scaling and utilizing path CD + spirit while playing angles shifts Kelvin from mainly a healing protector into a jack of all trades rounding out his lack of skirmishing power. Reaching 40+% ability range makes you untouchable late game with proper itemization and movement
