A channeled skill is a skill which can not be avoided by going invisible or becoming untargetable.
With some channeled skills, when casting them, any movement/auto attack/using other skills will stop the 'channeling' of the skill. A bar is shown near the bottom of the screen to signify when this type of channeled skill is being channelled.
Note: Becoming untargetable negates all channeled skill damage.
Also, there is a difference between a unavoidable skill and a channeled skill. A channeled skill has characteristics of a unavoidable skill though.
