Giant

You were a small creature when you were younger. (human, halfling, dwarf, etc) Teased for your size, even among your own kind, you sought to grow taller. One day you chanced upon a witch/wizard/sorcerer who promised they could make you taller. They enchanted a small amulet/piece of jewelry and infused it with giant's blood. As soon as you grasped it, you grew to a giant size. You were no longer ridiculed, but to a great cost. You grew insane, the cost of the blood, and the jewelry began breaking. It now has a giant crack in the middle. Now you can only be giant for a few minutes. Roll a d20 to determine size. 

Possible quests based on this character:

• DM can send your team on a quest to fix the jewelry. (ONLY DM READ THIS) On the way have the team find the person that gave it to you and learn that you will turn into a giant and become evil soon because every time you use the jewelry your own blood replaces the giants', and soon you'll only have giant blood and it will turn you evil.
