Infuse Item

Engineer: 2nd level You gain the ability to temporarily enhance a weapon or armor. At the end of a long rest, you can touch one unenhanced object that is a suit of armor, a shield, or a simple or martial weapon. Until the end of your next long rest or until you die, the object becomes an enhanced item, granting a +1 bonus to AC if it's armor or a shield or a +1 bonus to attack and damage rolls if it's a weapon. Once you've used this feature, you can't use it again until you finish a long rest. This bonus increases to +2 at 10th level and +3 at 15th level.
