You have learned the ability to increase the duration of weaves without maintaining concentration on the weave.
Minor rank in at least two Powers.
Player gains the ability to “Tie-Off” their weaves, extending the duration. For any spell with a duration unit, the duration unit can be increased by 1 for every additional 20% Source Points expended during the casting. However, the SP expended for a tied-off spell remain unavailable until the spell ends.
For example, Gaseous Form normally has a duration of 2 minutes per level, at a cost of 17 SP. For an additional 3 SP (17 * .2, ignoring fractions) it can be extended to 3 minutes per level. If Zydallon is level 15 with max SP of 200 and casts a double-duration (2 minutes + 1 increased unit (+20%) + 1 increased unit(+20%) ) Gaseous Form for 23 SP, that spell will last for 60 minutes (4 * level 15), and during that hour Zydallon's effective max SP is 177. Even resting (gaseously) for that hour will not restore those SP - they are still maintaining the tied-off spell.
This feat is considered a Channeling feat for the purposes of the bonus Wielder feats gained upon leveling.
