You mutter an ancient hex from a dead civilization. This vile whisper latches onto the target's soul, rending the life force from their body and leaving them withered. As an action you can speak this curse, targetting one creature, this creature must make a wisdom saving throw or take 3d10 necrotic damage on a success, taking half damage on a failure. On a failure the creature also suffers from a weakening effect that leaves them withered. In this incidence the creature has disadvantage on strength, dexterity and constitution checks and saving throws as long as you maintain concentration or until the duration ends.                                                                                                                                                                                                                                                          At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the initial damage increases by 1d10 for each spell slot above 5th
