So I was thinking about spell effect radius, metamagic feats and splash weapons the other day and found a way (not my idea) that we can make this work...I think.
Lets say we have a 'blast' spell. This spell would be defined with a spell radius, and thus would affect the target of the spell plus a number of characters on either side of the target. For example, with the following room contents:
A darkling minion scuttles around here.
A darkling minion scuttles around here.
An inky cat-like creature prowls around here.
An inky cat-like creature prowls around here.
[HOrc] Murgh the never-satisfied is standing here.
A darkling ogre stands here, its skin black as pitch.
A darkling minion scuttles around here.
Lets say we are a wizard, and we have magic missile, burning hands and fireball memorized.
First, we cast magic missile at the first darkling minion, doing a paltry amount of damage. It laughs at you.
Second, we cast burning hands, which has a radius of 1, on the first minion. The spell damages that minion and all other characters 1 position away from the minion, damaging the second minion as well. There is no character above the first minion, therefore only 2 of a possible 3) characters are damaged by the burning hands spell.
Lastly, we cast fireball at the first cat-like darkling. Fireball has a radius of 2, meaning that it can hit a total of 5 targets - the initial target and the 2 characters directly above and below it in the list. This means that 1.minion, 2.minion, 1.inky, 2.inky and Murgh all take damage from the spell.
A similar method would be used for splash weapons, giving them a radius. All effects with a radius can either have total damage for all targets or some kind of diminishing effect the further you go from he center of the blast.
I feel that the tactical options that this kind of targeting opens up are huge - target selection would be very important.
This system would allow us to have various metamagic feats that modify the spell radius, providing even more options to casters. Every application of the widen spell feat, for example, would raise the spell radius by 1.
This system would augment the current AoE code (but may potentially replace it!)
