Seems to work fine with human, previously mentioned glitches are gone. Works fine with Flame Pred and Die Xon. Works fine with both Pride and Power Up on Hell's demon.

Doesn't increase Crypt Lord's maximum health after to 200, but it does increase his current health by 50, so it can be at 200 for a period of time as per the prior version. Does increase Shadow Hunter's maximum health for healing.

Seems to reduce health properly when sold. Crypt Lord to 100, Human to 150, Santa to 100. If they had under these, didn't decrease health. Didn't test with a santa who had gained extra HP, or a crypt lord who had over 150.

While I assume you just meant to check the human issue, I decided to be thorough, just in case.
