I'm playing a game with a very lenient DM who is willing to let us customize things quite freely. Nothing really gets out of hand and it's quite fun trying to come up with inventive and original concepts.
I'm currently playing a pretty hard-headed female Half-orc barbarian who is trying to pursue the person who stole her precious childhood stuffed animal named Bunny. Her obsession and thirst for revenge is so powerful that she will eventually take on the the physical traits of bunnies: long teeth, fluffy fur, and maybe long ears.
You gain the ears of a rabbit. You can hear moderate-level sound up to two miles away...
...such as the approach of humanoids or the early signs of an oncoming storm.
