Either way the damage is applied in your system seems a little extreme, and would only succeed in pissing off veteran players, and intimidating new ones. Damage to or drain of ability scores can only be reversed by a restoration spell, which is not accessable until a character reaches the 4th caster level, and since your system affects Wisdom, it affects the ability to actually cast the restoration spell!

From http://www.d20pfsrd.com/basics-ability-scores/ability-scores#TOC-Wisdom-Wis- :

Read through that and compare it to your system. From what I understand, DE corruption in setting just makes you more likely to have lewd thoughts and be more predisposed to impulsive behaviors. Wisdom damage, on the other hand, is effectively brain damage.

From what I read from the source material, the effects of Demonic Energy do go away after a while, as long as its in small amounts and the "tipping point" has not been reached. I guess if you remove yourself from exposure after a certain amount of time, the energies dissipate.

Another critique I have of your method is how often damage is inflicted in your system. Each round is ~6 seconds of combat. This means that stuff like toxins, exposure, etc. will outright destroy a character in under a minute. Also, I find your lack of saving throws against corruption disturbing.

I started running a modified Pathfinder game set in the MGE universe. To this end, I and my players had to make a house-rule regarding corruption. It's a little in-depth, and requires the use of another stat to keep track of "corruption," but it should work. I'm not posting it here unless you really want me to, as it's not entirely complete.
