Desolate Dive

Strike the ground with a concentrated force of soul.

Desolate Dive can only be cast after landing 3 attacks with a melee weapon without casting a spell with a similar casting conditions. the melee attack effect stacks, so if you have landed 6 hits, you can Desolate Dive once and another spell of the same casting condition (focus, vengeful spirit, howling wraiths, shade soul, descending dark, abyss shriek)

Float a foot above the ground and swiftly descend, releasing soul in a 10 foot  sphere around you. every enemy in the radius must make a Dex save of 16 or take 2D12 force damage.
