Critical Mass Ray

When you start casting, you build up an atomic-like energy that can be detected within a radius 10x greater than this spells range. Anyone who can sense it will have a feeling of danger that is traced back to you. While casting the spell, you are treated as being under the paralyze condition & cannot move from the spot (voluntarily of involuntarily) or loose concentration. When you finish casting this spell, all creatures you can see in a 60ft cone save take 20d20 poison damage split between the creatures. All creatures in range can make a Con save to halve the damage they would of taken. If you loose concentration on the spell, you take 1d20 poison damage for every round you had been casting the spell.

For every level above 1st you cast the spell at, reduce the casting time by 12 seconds (2 rounds).
