Sirene Primer+Free Or Non Actions+Inspired_Surge

Benefit: When casting a sphere effect, you may increase the wild magic chance by 100% to add a single talent that you do not possess from one of the effect’s base spheres to the effect. For every 5 wild magic feats you possess, increase the number of talents gained this way by +1. You must still meet any prerequisites that the talents possesses. When gaining multiple talents with this feat, you may use a talent gained this way as a prerequisite for other gained talents.
