Victor (Nivel 6) mail warning

For those who want to lean into the more vampiric overtones, an extra challenge...

Any time Victor grabs, holds, or pins you, both characters will roll a d10, and if Victor wins, you'll feel his fangs sink into you, draining some of your strength and will. The draining is more magical than physical, and some even describe it as quite pleasant. With each bite, your dice will drop by one (so next time you'll roll only a d9, then a d8 if Victor succeeds again, etc...). At first the only effect will only be to the dice you roll, but with each new bite mark, your resistance weakens and the real danger arrives.

Each failure at d7 and below, and any powers you have receive a -1 penalty
Each failure at d5 and below, you skip a turn and any powers you have receive a -2 penalty
Each failure at d3 and below, you skip a turn and Edge (if you like)...*
Fail your d1 throw...which you almost surely will...and you can no longer resist, surrendering instantly.

The goal here is a mechanic that will have little effect at first, but can quickly cascade near the end feeling more and more helpless, while of course adding some extra fun to the basic thrust of the character...pun lewdly intended. It is very much in its "trial and error" stages, so suggestions are welcome, including how to combine these with hypnosis and bondage rules.
