A Spray gives each creature a 20% chance to miss, or an 80% chance to hit.
For six Sprays:
0.8 * 0.8 * 0.8 * 0.8 * 0.8 * 0.8 = 0.262144
Each creature would have about a 1 in 4 chance of hitting, at a cost of 18 fire quanta per turn (12 if upped).
I think this seems UP in terms of cost - could do with being cheaper, but I'm unsure how to reduce the cost.
Perhaps add a "Generate
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
per creature that hits" as a single ability shared across all Eaters? Is that even possible? Probably not. But I still think it seems too expensive.
EDIT : I realise I have overlooked the deal 1 damage thing. No, this is not too expensive.
