Other Ideas for the Catch, your thoughts?

[Mr. Ghostbuster]

I'm helping someone put a game together and one of our players wants his character to have a Catch that is mental in nature, rather than physical. He's building a character who I guess fuels his physical abilities from being possessed by a powerful spirit and that if he behaves in a way opposite of the spirit (its a Spirit of Justice), it somehow satisfies the Catch. In theory I don't have an issue with this, in fact it sounds kind of interesting. The only concern both the GM and I had is that it stays balanced obviously. Does anyone have any thoughts or ideas on this? The obvious solution is to have the Catch somehow affect his mental stress or maybe use a vampire sheet and use the hunger stress track.

You might want to check out (and adapt) my Demonhost Template. No idea about the Mental Catch though. Maybe make it so that if a character attacks them and the attacking character is in hte right, the Catch is satisfied? Although, this would definitely be a +0 catch.

What type of toughness powers does he want? If he only wants inhuman level powers, then a [+0] catch will work just fine. If you want to grant the player some refresh back, you could attach it to human form (involuntary change), which will then be sort of like the catch. The human form trigger would then be anything that would oppose the spirits agenda.
If he is going for more than inhuman, I would require him to take up a catch that can be met by other people, simply because he will become nigh invincible otherwise.

A Catch is supposed to be a means of attack that the opponent can discover and use to bypass the character's defenses.  This sounds more like a Human Form (powers conditionally available) or an aspect to be compelled when the character misbehaves.

The Catch Rewrite that was worked on a while back might be of some use, here, if someone wants to dig that up (Sanct?).
It basically amounted to providing a Refresh rebate in proportion to the likelyhood of any given scene seeing the affected Powers bypassed by means of the Catch.
So, you'd work out an estimate at character creation (or whenever the Power is acquired) for how often this will happen, assign the appropriate rebate, and adjust during play as necessary to match the actual trend that develops.

The master list thread contains both mental toughness and a revised Catch. Check reply 522 and reply 547.
