Let's see. The Hellbender paradigm says:
"Even the devil can be tamed if you know his weaknesses".
This paradigm indicates that the magician is someone who deals with secrets and manipulates weaknesses. Maybe in a John Constantine kind of vibe. This can be interpreted in several ways, for example:
- Performing a ritual to discover an enemy's weakness, such as a fear or a desire.
- Manifesting someone's fear, after discovering it.
- Concentrating for a moment to discover the weak point of a structure, such as a wall, where even a punch could knock it down.
- If you know someone's weakness, you can give them an order that they cannot refuse.
- Forcing someone you have done a favor to do something for you in return.
- Perhaps summoning lesser demons to perform small services, as long as you compensate them adequately.
- Forcing someone to assume their true form if you know their true name.
And so on. The idea is to extrapolate the interpretations of the paradigm to create evocative effects.
