// XXX: Should this also check for the amulet?

//
// Avoid the following cases:
//     * undead players who can decompose (potentially lethal)
//     * players with the full mutation resistance mutation (useless)
//
// Don't avoid the following cases:
//     * players with amulets of resist mutation (sometimes fails)
//     * players who resist mutation due to high Zin piety (same reason)
