RTF is a global modification that replaces all towns in the game.

I was doing it with the lich's beam... targeting the enemy is buggy and sometimes it stretches to the wrong one (like the effect of death cloud). Plus there were times when you shoot at one, but another ends up taking the damage... And the funniest thing is that the beam was taken from "Demilich" — that's the alternative one which doesn't have the death cloud effect.

Actually, I like the cyclops' red beam... but it needs to stretch from the eye to the enemy even if they're 10 tiles away.

I don't remember the specifics of the lich's shot, but I've already used their beam for the cultists' evil eye, seemed fine

there's also this point here — maybe the bug isn't in the shot, but in the unit — I for example sometimes forget to fix projectile hit points for units, then for instance a shot can fly over the head of a dwarf (if I took a big unit as a base)

the smoke from the lich's shot I think is tied to the line <StrikeEffectID>SPELL_ABILITY_DEATH_CLOUD</StrikeEffectID>, only liches have it
