Tides of Blood (Remnant)

You create a compressed ring of blood that surges around you. At the start of each of your turns while you are concentrating on this spell, you increase the range of this spell by 5 ft (to a maximum of 60 ft).

When the spell ends, you unleash a nova of blood bolts which hits each creature within range (other than yourself). Any creature hit by this effect must make a dexterity saving throw or take 3d6 necrotic damage + the hemomancy cost and have their movement speed reduced by 10 ft until the end of their next turn. On a successful save the damage is halved and the creature is not slowed.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
