Upheaval channeling.
Channeling causes the caster to stop acting for the duration of the the ability.
Channeled abilities may be ended early when the channeling unit performs another action or is interrupted by another ability or disables. While abilities are being channeled, a time remaining bar will appear on the screen, indicating how much time is left in the channel. Silence stops ability channeling, while Mute stops item channeling.
Interrupting Channeled Abilities[]
Performing the following actions while channeling abilities will interrupt the channel:
- Issuing another command (i.e. to move,
Left Click on ground, stop, attack, A on target). - Casting other abilities or using items (with certain exceptions).
- Any disables that would normally prevent a unit from casting abilities.
If the channel is interrupted before the ability's effects occur, the mana and cooldown will be wasted, and the ability's effect will be cut short, and in some cases will not perform their effects at all. This is in contrast to other, non-channeled abilities with high cast times (e.g. Assassinate and Requiem of Souls) which will not expend mana or go on cooldown until the ability has been completed. Certain channeled abilities (e.g. Illuminate and Powershot) will still perform their effect even if they are canceled, usually at the cost of damage.
Any disable that would normally prevent a unit from casting the spell in question will also interrupt channeling. This includes stuns, cyclones, hexes, sleeps, and getting hidden. Though they do not prevent casting, most root effects will also interrupt channeling. Silence will interrupt channeling from abilities only, while mute will interrupt channeling from items.
Some abilities that applies Forced Movement (e.g. Vacuum or X Marks the Spot) will interrupt channeling as well, even if used on friendly units; however, other abilities like Force Staff and Boulder Smash, will not interrupt channeling, apply forced movement and not causing an interrupt state.

Patch History[]
- Fixed status resistance affecting the duration of the next cast of channeled abilities.
- Fixed a bug where non-stun interrupts did not reliably cancel channeled abilities if cast an instant before the end of the channel.
- E.g. Casting Nether Swap on a target at the last tick of channeling Town Portal Scroll.
- Fixed a case where channeling would not be interrupted correctly with a non-stun interruption on the very last tick of the channeling duration.
