Evandor's Gracious gift

You paint the workings of a spell you know onto a willing creature, once before completing a long rest, or untill dispelled, the chosen creature can use its action to cast the spell as if they had cast it themselves. Spell Attack bonus and Saving throw are determined by the caster of THIS spell.

When you cast this spell, you use the spell slot to cast this spell, as well as the spell slot the spell you give as a gift would require.

When the chosen creature casts the spell you gave it, this spell ends. 

You must cast this spell at one level above the spell you wish to gift. To gift a cantrip cast at 1st level, to give a 1st level spell cast at 2nd level, to give a 2nd level spell cast at 3rd level, e.t.c.
