I was thinking of it more spreading east to west columns sort of thing and just being a spell.
Fire has too many spells in its arsenal already, not to mention that if you want the lava to
'spread', it would take multiple turns to do it, and
spells occur within a turn at max. If it's a permanent, you can put a doomclock on it (timer), and have it so that every time the lava moves from one section to the next, the timer ticks down. Thus, if you place one down, it'll go from one area to the next while ticking. If you place multiple ones down one after the other, however, each area could have a potential overlapping effect (where no creature would be safe played in the middle).
On a sidenote, if this is going to be an environmental effect, you should increase the cost proportionally (see flooding). Also, since
and 'non-flying' (
) creatures are not going to be effected, then what about dragons? Aren't those flying creatures as well? Or flying weapons?
Instead of an eclipse ripoff, why not make it a flood ripoff.
For some added fun, make the middle row a flaming river of fire, which wounds the middle row non fire/non flying creatures by 1 on your turn.
You've read my mind Avenger.
