Water Of Vitality

You touch a mug/waterskin of water. This Mug becomes blessed with magic. You can then take an action to drink 1/4 of the container's contents and heal 1d6 + Spell casting ability modifier. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing increases by 1d6 for each slot level above 1st.
