Was just wondering if it's possible to implement this metamagic.
It Doubles the area of effect of spells.
Spread, Cloud, Burst and line spells are affected by it, ray spells are not.
Speadspells are ones lilke burning hands, colour spray, acid spray, cone of cold
Cloud spells are acid rain, stinking cloud, grease with durations
Line spells like lightning bolt
Burst spells are instantaneous sphere effects like fireball, otilukes freezing sphere.
For example a widened: Cloud kill would be double the area, and probably double the mana usage.
