Pyrotechnic's Skill Set (In Progress)

This is the list of every skill which the Spiritual Fire class, the Pyrotechnic, can learn. The Pyrotechnic specializes in dealing damage to several monsters at once. The gaps indicate levels I haven't composed a skill for yet. The bottom list called "Bonus Skills" contains skills that are acquired through slipstream rounds.

Lvl. 3: Flash Bomb (uu) - Does 1 u damage (regardless of enemy's type) to 1 monster, and disables that monster for 1 turn.
Lvl. 6: Refuel (u<3) - Attacks that connect may now do +2 damage for the duration of the round. (Does not alter the damage dealt by other skills.)
Lvl. 9: Crowd Pleaser (uuu) - Does 1/2 damage of total cost to 3 monsters (regardless of their type).
Lvl. 12:
Lvl. 15: Incinerate (uuuu) - Destroy the active Base of 1 monster. Attack the remaining monsters with 3 u.
Bonus Skills
Lvl. 4: Barrage (u<) - Fire 1 Firecracker at one monster, then do 1 u damage to the same or a different monster.
Lvl. 7:
Lvl. 10: Finale (Au) - Draw six cards. If any of them can be effective against any of the monsters on the field, attack with them. Discard any cards that aren't used.

Lvl. 10: When attacking multiple monsters, you may add +1 damage to each target involved in your attack.
