Another Experimental Marvel Heroes Mechanic

This rule activates when a player decides to use karma for a dice roll.

Normally, the makes this announcement, but doesn't have to decide how much to spend until after the dice roll. The minimum is 10 points.

With my rules hack, the character has the option to decide in advance how many points to use, and what level of success she desires. The minimum is still 10.

If the character succeeds with beyond the minimum required for the announced result, the player has earned the right to control the manner in which the success occurs. This is a 'yes and...' success. The player's creative control includes the ability to introduce a helpful non player character or affect with a maximum characteristic equal to the extra karma.

The player can also introduce additional obstructive NPC's or affects to receive a karma refund (or bonus) equal to that character's maximum characteristic.

Karma points are also refunded based on player creativity.

If, however, the player fails in spite of the karma use, one of two things happens. If the player would have succeeded had they used 1.5 times the amount of karma used, the character fails forward. This can be thought of as a 'yes but...' result.

For example, Benjamin is playing Thor for a session. Ben decides that Thor really needs to knock out his opponent during his next attack. In other words, he needs a 'stun' result on a Fighting roll. Thor's Fighting score is Unearthly, so he needs a roll of 86 or better for a red result.

Ben decides in advance to use 30 karma points on this endeavor, then rolls the dice.

If he rolls a 98, he has a total of 42 extra karma points ([98-86]+30) and has earned the right to control the scene. Since 42 falls in the 'Incredible' range, when Ben narrates the action, he may introduce new beneficial characters or affects with up to a max score of Incredible. He may also choose not to introduce anything. Either way, Ben is encouraged to be creative with his description. Have fun!

On the other hand, if Ben rolls a 73, Thor has trouble. While that normally would have resulted in a yellow fighting success, it misses the announced mark. The good news is, that if Ben had spent 13 more karma, it would have succeeded: this earns a 'yes but' success. The judge (GM) narrates "Thor hits Mega-thug, which slams the now unconscious villain into the pillar. The force of the impact shatters the load bearing pillar, and the building starts to collapse."

The character can not succeed beyond the announced result, and any successes less than desired are 'yes but' types of tainted success.
