CHANNELING
Abilities that persist while actively maintained — held buttons, drained resources, sustained beams — trading continuous effect for continuous commitment: the channeler can't act, and often can't move, while the effect runs.

Diablo III built whole builds around channeled skills (Disintegrate, Whirlwind's spiritual kin), with resource drain and legendary items tuned specifically for stand-and-hold play. Genshin Impact uses hold-cast and sustained skills whose duration and vulnerability windows differentiate them from tap variants of the same ability. Designers use channeling to create a distinct rhythm from cast-and-forget abilities — commitment under pressure, where the question is not whether to cast but how long you dare keep casting — and to price strong effects in ongoing exposure and resource flow rather than a cooldown. Channeling also produces great enemy design targets: an enemy channeling a devastating effect is a legible, interruptible priority. Key decisions: what breaks a channel (movement, damage thresholds, stuns) and how much of the effect is lost, whether the effect ramps while channeled — escalating beams reward daring — and how channel state reads visually to allies and enemies. Pitfall: channels in games whose core verbs punish standing still; if positioning pressure never relents, channeled abilities become theorycraft traps that no one uses past the first death.
