Energy Charging:
After spending 3 hours under the sunlight, this weapon begins glowing. You can spend this charged energy and cause 2d6 extra fire damage.
Shadow Regeneration:
When in total darkness, you regain 2d6 HP at the start of every round only when wounded, and it stacks with other regeneration forms like Fast Healing. Every time this happens to a creature that doesn't have the Demon subtype, there is a chance of 25% that it will undergo one of 7 stages of transformation into a Shadow Demon. From the 4th stage onwards, you will gain a second personality that will grow in strength as the stages continue, eventually taking full control at the 7th stage. This effect is completely irreversible without the use of a Wish or Miracle and will have a visible effect.
Shatterer:
when used to break equipment treat this weapon as if it had a +5 enhancement bonus, applying the corresponding bonus to attack and damage.
I would place Energy Charging as a +1 enhancement bonus, and Shadow Regeneration and Shatterer as +2. Would this be balanced, or am I overlooking something?
Thanks in advance.
