DT: +1 per 2 damage.
When casting this spell, you may deal additional damage up to the Rank of this Augment. Unfortunately, this destabilizes the spell, making it more difficult to cast. The Check DT increases by 1 for every 2 additional points of damage this Augment adds, rounded up. So, if you have this Augment at Rank 4, you may add 1, 2, 3, or 4 additional damage, and the DT increases by either +1 (for 1 or 2 additional damage) or +2 (for 3 or 4 additional damage).
This Augment does not increase the Mana Cost.
