Sporeray Weapon: Sporeray weapon will be changed so that it is, in fact, a spell. They will fire spores at a slow rate that cause AOE Poison effect. (Perhaps Spore Cannon Weapon model?)
Remove Sporeray Leaping, and instead give them a new spell: Flight
Flight temporally converts Sporerays into fliying creatures (Using Viking or Colonist Ship effects?). It consumes energy at a fast rate, and the spell ends once canceled/sporeray run out of energy.
New Reproduction Form: Sporerays with full energy that die in battle will create two sporelings, which will be weaker than they re currently, but faster. Sporelings that are feed enough spores will grow into Sporerays.
