Level 15 brings 5 build points, and unlocks T2.
Since there is no big choice of spells for level 15, this spell order comes natural.

1-Discharge - Only assault spell that boost up Power Cores;
2-Quantum Cascade - One of the best main resource spending abilities. It grows in size as you channel it. Without mentioning the size of Telegraph, this spell is much better than Gamma Rays skill, because of higher damage and channel time, instead of cast time;
3-Particle Collider - If any creature survives Quantum Cascade skill, what can happen with a small chance, Particle Collider as instant spell will finish it;
4-Urgency - Although, this ability sometime requires a flat area without obstacles in front of you, it is useful for fast moving;
5-Fissure - At this level, Fissure should be your opening spell, as it increases damage on other technology based spells;
6-Paralitic Surge - Defeating group after group of enemies is possible with this skill, since it stuns the enemies for 3 secs, and you don’t need to wait for your health bar to fill up;
7-Nullification Field - This spell is here for fun. It makes a pretty epic sound and graphic. Snare is also useful but not that great;
