Alright, so below the two ways I would approach it, the first I like better b/c simplicity
##Backbiter (or feedback)
Duration: Resist ends (Fail x3 = 1 minute)
Power Level: 6
Attack Attributes: Entropy, Influence, Protection
Attack:
- Entropy vs. Toughness
- Influence vs Resolve
- Protection vs Toughness
Description
Causing the worst Karma, technological malfunctions, or an aura of reverse protection, the target is forced to lose their own life force if they choose to harm another’s life force.
Effect
Upon a successful attack roll, the affected target takes half (rounded up) the amount that exceeded the defense score as damage to themselves. This damage automatically bypasses the afflicted character’s defenses, but can be reduced by any resistance to damage of a certain type (see the resistance boon). The original attack still goes through.
For example, Zoom the Eleven is affected by the Backbiter Bane. They go to inflict Blinded on a target, rolling a 23 Energy vs 16 Guard, successfully inflicting Blinded. However, they take a total of 4 damage (23 - 16 = 7, divided by 2 = 3.5, rounded up is 4) to their own HP.
##Backbiter (or feedback)
Duration: Resist ends (Fail x3 = 1 minute)
Power Level: 4/6/8
Attack Attributes: Entropy, Influence, Protection
Attack:
- Entropy vs. Toughness
- Influence vs Resolve
- Protection vs Toughness
Description
Causing the worst Karma, technological malfunctions, or an aura of reverse protection, the target is forced to lose their own life force if they choose to harm another’s life force.
Effect
Upon a successful attack roll, the affected target suffers damage to themselves determined by the power level of the bane. This damage automatically bypasses the afflicted character’s defenses, but can be reduced by any resistance to damage of a certain type (see the resistance boon). The original attack still goes through.
-
Power Level 4 - 1 damage for every successful attack roll
-
Power Level 6 - quarter (rounded up) the amount that exceeded the defense score as damage
-
Power Level 8 - half (rounded up) the amount that exceeded the defense score as damage
For example, Zoom the Eleven is affected by the Backbiter Bane at power level 8. They go to inflict Blinded on a target, rolling a 23 Energy vs 16 Guard, successfully inflicting Blinded. However, they take a total of 4 damage (23 - 16 = 7, divided by 2 = 3.5, rounded up is 4) to their own HP.
those would be my suggestions, but again, I favor the first one with just 1 PL more. When you are already halving damage, unless you have a big explosion, it won’t be very big to begin with.
