Fire Demon is widely accepted as having a larger range than Explosion. However, my data proves otherwise.
According to Fiel's Skill Tables (and Skill Tables everywhere else), Fire Demon has 300% range. I think this is misleading, because it makes Explosion, which has 200% range seem a lot shorter, when really, Explosion has a farther range than Fire Demon.
Explosion has 200% range. Notice I can still hit both when standing on one side.
When using Fire Demon from one side of the two Leps, if Fire Demon's range is better than Explosion's, I should be able to hit both. However, I find that I cannot hit both Leps with Fire Demon.
When standing on one side of the Lep, I hit the one closest to me.
When standing on top of the lep, I hit the one farther from me.
Thus, Fire Demon has a smaller range than Explosion. It's interesting how the skill has been out for so long and yet it is still widely believed today to have a larger range than Explosion.
I'm just talking about range (look at the title, hint, hint), not how the skill is used!
