Feat
Arcane Fusion
Two spells in one gesture
The caster fuses two spells of different levels into one improvised spell.
Both slots are spent. The fusion uses one action chain, that of the slower spell, with one Action Board slot at each step. Both effects occur together on the same target or area, using the caster's CL and the higher spell DC; damage is added.
If the effects cannot coexist, the GM uses the higher spell's geometry or refuses the fusion before payment.
Uses: Charisma ÷ 3 per day, rounded down. At +10 Charisma, the caster fuses three times. True Talent removes the different-level restriction.
