I have a player that wants to build Midoria (aka Deku) from the anime My Hero Academia. How would you build a character that is full power (10) in Movement & Might (Attribute Substitution 2), but is Level 1 in everything else and takes damage from using his power?
This is what I’ve come it with (but I’d like to hear what ways you would make it work):
I tell him to choose which Power Level (0-10) he wants to use his power at. Then I have him make a Will roll to see if he succeeds at limiting himself to that Power Level, or if he overpowers - and by what amount. I am using the Heroic CR of 20 and scaling the amount of overshoot by how far below the CR he is. Then he rolls the PL that I tell him. After calculating the damage (if any) to his target, we compare his attack or jump (Teleport) roll to his Toughness. If it is above his toughness, he also takes damage - but not the full amount. He takes a fraction of that damage based on his Fortitude score. I’m using the calculation (1/(Fortitude+1))*Damage to determine the amount of damage he takes. So, at Fortitude 1, he would take 1/2 of the damage. At Fortitude 2, he would take 1/3rd of the damage. And so on. (I’m considering changing it to (1/Fortitude)*Damage to make it hurt more.)
The problem I’m having with this is that he also takes actions without activating his power. So, we have his Movement > Might set at 5. This creates a situation where he does an unpowered punch at PL5 and takes no damage, but does a powered punch at PL3 and does take damage for a less damaging punch. I’m not sure how to fix this.
I’m really interested in seeing if the community can come up with a better way to do this, especially if it can do it without my houserule calculation, using only the unmodified rules.
