Unmovable Object

Use this Technique no more than once per day.
Your body becomes supernaturally dense, heavy,
and durable. Until your next turn (or for the
next 10 seconds), anyone or anything trying to
move or lift you takes a severe penalty. If you
would receive damage during this time, roll
2d6. If the unmodified result is 6 or higher,
you receive no damage instead.
