You decide to take the crystal. As you pick it up, you feel a strange energy coursing through your body. The crystal starts to glow brightly and you can feel its power flowing into you. Suddenly, you realize that you have gained magical powers.
You test your new abilities and you find that you can control the elements, summon creatures, and even teleport. You feel invigorated and empowered. You realize that the crystal was not just a simple rock, but a powerful magical artifact.
You start casting magic, so much so you start to overload, as power surges and overwhelms you, everything fades away.
