Overpowered

Your body becomes permanently infused with intense energy, giving you an incredible increase in power, but the energy takes a toll on your body deteriorating it much faster over time. 

You gain the following benefits:

• You gain a permanent addition to all of your ability scores equal to its current nonadjusted modifier.
• You gain +5 to saving throws against the spell slow.

You gain the following penalties:

• You can no longer gain ability score increases or feats during level gains. 
• After a hit dice is gained from reaching a new level, roll 1D4 and permanently remove it from your maximum hit points. 
• You age twice as fast, and all aging effects and negative status effects are doubled.
• Your length of life is permanently cut down by half. 
• For every round you after being affected by haste, you permanently lose one year of life.
• If your hit points ever reach 0, you die instead of being unconscious; this feat is permanently removed, and its effects are lost.
