Shadowmancer has a simple design which is not bad because it makes into a viable filler class but it feels too simple and ain’t much mechanic to synergize aside from linker. This are just my suggestions.
I do think they are also lackluster but I do hope IMC plans to furnish this class more.
Shadow Thorn - For every X(3?4?5?) seconds the Hallucination(shadows) or Infernal Shadow casts a Shadow Thorn to a single nearby enemy.
Shadow Pool - Applies Darkness to enemies who come in contact during this form.
Shadow Fatter - Decreases Target’s Evasion Rate by X%.
Hallucination - after casting, activating the skill again would teleport you into its location.
