APPARENTLY, the dice tossing skill deletes whatever you have equipped when you throw the dice instead of just deleting one die from your inventory. WHICH MEANS, using Tiara's Moonshine mod for a the ability to equip items with any skill charged, you can begin the dice tossing action, equip Eiry, and throw Eiry away! :D. (This works with anything you can equip to a weapon slot.) Here are step-by-step instructions on how to do this if you haven't figured it out by now.. First: Equip dice. Second: Start the dice rolling action. Third: Equip Eiry while the die is in your hand. Fourth: Throw the dice. A bit of advice.. Do NOT THROW AWAY YOUR EGO. It may mess up your ability to obtain another ego. I suppose you're welcome to try this if you have a useless character with an ego, but it might seriously screw you up if you try this on an important character.
