Made of Good

Positive emotions and virtues like love and gratitude usually are not physical concepts. You can't see them; you can't feel them.

But they are now! These objects are materialized out of good feelings. Whether they power you up, you need to collect a bunch of them for some purpose, or they make a weapon for you to use, they are physical manifestations of goodness. On occasion, you may find a living being made of it.

Compare Care Bear Stare, which is instead an attack, not object, of positive emotion. A weapon made of this may overlap with Holy Hand Grenade and/or Silver Has Mystic Powers. Contrast, obviously, Made of Evil. See also God of Good.
