Fermata

Description
The poison and Mana gains are actually applied five times per second (2 poison and 0.3 Mana per tick), keeping the timer on the poison virtually full at all times during use.

Strategy and Synergy
Fermata can be used without penalty as long as the user does not 'miss a beat' and allow their poison timer to tick down. Extreme caution must be used when a potentially lethal amount of poison has built up, since spending your last Mana point or casting another spell with Anchor at the wrong moment can prevent you from using Fermata again until it is too late.

Trivia
In an orchestral composition, a fermata is a musical note sustained for an indeterminate amount of time. This reflects the channeled nature of the weapon, which can be used for as long as the player likes.
