Works like a charm
Potions. We love 'em. We fill our Bags of Holding with them, because they bring thaumaturgy to those of us who aren't actual magic users. This is important because you never know when your party healer is going to go down. And the smart enemies know he or she has the fewest HP in the party. One hit, and whammo. No more healing for anybody. It's going to be a long, painful battle, filled, with blood, sweat, and potions.
It's time to bring the potion home with you with this LED Potion Desk Lamp. This little bottle may not look like much, but it's filled with magic (Ed. note: it might technically be science and/or resin). Tap the base and invoke the word "LUMOS!" to light it up. Tap it and whisper "Colovaria" to make it magically change color. Give it a tap and say, "I don't actually have to say anything because this lamp is touch-activated" to switch colors again. That's right. It's like an old-fashioned tap-on/tap-off light except you tap this one to change modes: solid red, green, yellow, blue, or a slow fade across the spectrum. A sensor combined with an LED in the base does all the work for you. All you have to do is plug it in and let the magic happen.
