Conjure Blights

You deal 2d4 necrotic damage to yourself or a willing or restrained creature, then summon blights that appear in an unoccupied space that you can see within range. You choose one of the following options for what appears: Two tree blights (found in the Curse of Strahd module) Four vine blights Eight needle blights Ten twig blights A blight summoned by this spell disappears when it drops to 0 hit points or when the spell ends. The summoned creatures are hostile to all creatures, save for undead or other blights. If you used your own blood in the spell, the blights will be friendly towards you, but not your companions. Roll initiative for the summoned creatures as a group, which has its own turns. You may order the blights to undertake certain courses of action, but cannot prevent them from attacking a certain creature; you can, however, order them to prioritize a certain target over others. If you don't issue them any commands, the blights will attack the nearest creatures to them, prioritizing the weakest target available
