Dr.Robotnik, you HP isn't increased at all. Instead, you get a lovely armour boost + special effects. Your hearts will never be 1000. That's how many hearts you take before you die.

Effective Armour Ratio (not official):

For every 8 hearts you are suppose to take per tick, you only take a heart. Does not included monster attacks (18 hearts= full heart), Nukes (instaDeath), Other Infernal armour, Red Katars, and hunger bars/poison (normal damage effects).

Boosts

DM Helmet: None

Infernal Armour : You take no fire/lava damage. Blow stuff up with C

Gravity Greaves : While falling, hold Shift to fall faster. In addition, holding Shift repels mobs.

Hurricane Boots : No fall damage if not sprinting. Fly with Space.
