Thesalor's Magnificent Plan C

Capture -(1-5) Up to 4 targets in a 30ft radius within 60ft that you can see must make a DEX saving throw or be restrained until they succeed. Snake like ropes spring up and wrap around targets, restraining them.

Conceal -(6-10) Up to 4 creatures you choose within 30ft of you and that you can see, become affected by lesser invisibility. The shadows of the targets recede, as they do the targets become invisible. Moments before the spell ends the shadows reappear first.

Cure -(11-15) Up to 4 creatures you choose within 60ft and you can see, are healed for 4d4+(spell modifier). A lovely flower sprouts from the heads of the 4 targets. It grows until it blooms, then it sheds its petals and harmlessly falls away.

Cull -(16-20) Choose 4 random enemies you can see within 60ft. If their combined hit points are less than you’re hit points at the moment of casting then the targets drop to 0 hp. If their combined hit points exceed the caster’s current hp each target takes 2d4+(spell modifier) of necrotic damage. Scythes appear behind the targets and try to lop off their heads.
