So what if, when you harness the codex to sacrifice your demon, tou infuse yourself with whatever demon you have summoned.

You still get their special attack, but in addition, tou get an extra power and some visual additions;

- Imp; horns, a tail and baby wings - being able to jump a long distance
- Voidwalker; extra void arms - being able to taunt
- Felhunter; thorns, spikes and tail - being able to dash foreward
- Sayaad/Succubus; wings, horns; being able to teleport behind the target

What do you think?
