This incantation prepares the mage to enter a trance where she is ready to
unleash single blasts instantenously. Maintaining the trance is extremely
delicate, and it can only be maintained for very short periods of time. High
mastery helps, but even the strongest minds can only concentrate for brief
moments. Actually unleashing the spell is even harder, any distractions can
seriously affect the casting. The best way to complete  the trance without
distractions is to stay away from other players, as any distracting presence
can seriously affect the outcome. Being in trance in the presence of bigger
opponents may be dangerous, as you are not concentrating fully at the combat.
Unleashing powerful blasts from the trance is taxing, causing the next trance
to take more time to establish.
