Fireball doesn’t affect all monsters in range.

As the title says. When I cast fireball or snillocs the monsters in range (15’ radius) aren’t all hit. Im talking about monsters all grouped into a crowd like a horde of lizard men and a group of cold wights here.

This has been a problem since before the enhanced editions. Many area of effect spells have difficulty hitting moving targets. Basically, any target that walks away from the source of the explosion is likely not to be hit by it. This happens with spells that use a certain invisible traveling projectile, which is just what it sounds like; a projectile that moves from the center of the explosion to the target, without being visible to the player. Most of the spells that use this projectile are area of effect damage dealers such as Skull Trap, Fireball, etc, but there are several others.

I’ve played the game since it came out. I’m talking about with a group of 5 in range, and still in range upon detonating, it only hits 2. Two. The flaming oil thrown by my Paladin actually hits more than my fireball thrown by my sorcerer.
