Notes

Unlimited Health:
Toggle on and most things cannot harm you.  You MUST have this on if you plan to teleport distances.

Unlimited Medicinal Pouch:
Toggle on and the meter remains full.

Unlimited Underwater Breathing:
Toggle on for effect.

Unlimited Party Health:
Toggle on and the trainer will try to keep party or friendly units full of health.  Probably best to turn off before BOSS fights to prevent some encounters from being unable to continue.

Unlimited Use Items:
Toggle on and most items when used it will not decrease.  Not this may affect some ammo items.  Some ammo this will multiply the amount fired as well.

Unlimited Arrows:
Toggle on and your arrows and possibly other ammo types remain full.

Ghost Hunter Mode:
Toggle on and enemies instantly cannot see you, and you are completely invisible and silent to them.  You can bump into them, kill them, move at will for most enemies.

Silent Hunter:
Toggle on and most enemies cannot hear you, but can see you.

Invisible Hunter:
Toggle on and most enemies cannot see you but can still hear you.   Once you have bumped or alerted them, they may be able to attack.

Weak Enemies:
Toggle on and most enemies are much easier to kill, especially after they have had initial damage.

Easy Craft Items:
Toggle on and most items can be easily crafted, even if you do not have the materials.
