Consumable Effects

When you use a consumable item as a material, its properties become a charge effect. The effect can be activated once per day, and you regain the ability to do so after completing a long rest.
Every time you use Tuning to add another duplicate of the same consumable to your Echo, your Echo gains an additional “charge” for the item in question. In other words, if your Echo has three potions of healing attached to it, then three times per day you may gain the benefits of a potion of healing without using an actual potion of healing.
It’s up to you to decide how the Echo delivers these properties to you, no matter what shape or form your Echo takes.
