Dungeons & Dragons 5e Element 133 Program: Mend

You repair any big holes, cracks, blemishes, etc. on an object. You cannot restore power to an item, only repair its form. You must use an appropriate element such as metal or fire for a weapon or even organic for wooden shield. You may mend an object with a separate element, not used to repair it normally, but -1 from its normal ability to a minimum of 1 (ex. Your Longsword now does 1d8-1 Damage, you shield only gives +1 AC, etc.)
