How do I make it killable?

[SlimyWaven (SlimyRaven)]

I’m new to deving and I want to make this guy killable which i have no idea how to do that and simply adding a humanoid to it doesn’t help. HumanoidRootPart is the mesh that I want to be killable but when i’ve tried multiple ways to make it killable though everything i’ve tried has never worked.

You can add a Humanoid to it or use a NumberValue which indicates the HPs. When it’s damaged you can use Humanoid:TakeDamage(hpToRemove) or NumberValue.Value-= hpToRemove
