Be "Skids" O'Toole or Tony Morgan, throw a Dynamite Blast in a connecting location, play "You've had worse...", tell your friend that for 3 resources he can cancel the 3 damages you have just dealt to him.

Rogues are known to be sketchy, but paying yourself?! I guess the potential weirdness of this card is limited by having to give the resources all at once, but as long as you have 5 (which is easily doable as one of the greens) this card is more and less flexible than Deny Existence at the same time:

• (-) You can only choose damage and/or horror.
• (-) You can only cancel 5.
• (+) You can mix damage and horror.
• (+) You can target other investigators.
• (+) You can target investigators at connecting locations.
• (+) Damage/horror can come from player card effects.
