[Celjabba]

Edit : upgraded to "power modifier, cosmic : +50%" on everything instead of just UK3 and unaging, and added temperature tolerance, and heal radiation. Gone from [1000] to [1500]

Immortal [1500] :

You cannot die.
You don't age.

You ignore any hp damage and associated pain and penalties, although you still suffer knockback or follow-up effect.
You ignore poisons, diseases, radiation, high and low pressure and pressure change, are comfortable in a 3175° wide temperature zone (from absolute 0 to ~2220° (based on HT10) ) and don't need air, food or water to survive.
Your body and your mundane clothes are never visibly damaged.
Carried items may get damaged but follow you when you flicker.

If you would have taken over 10 point of injury in a single turn (or suffer from a 'you are dead' effect like an hearth attack affliction), you flicker for one second on the next turn.
If your body is in a situation where it couldn't avoid being damaged (between crushing walls, fallen in lava, ...), you flicker for one second and appear at the nearest open and safe point.

-------------
Upgrade package 1 [195]:
This grant protection and self-repair to all carried gear

Add ";also affect payload, +100%" [+150] to Regeneration
Add ";forcefield, +20%" to :
Pressure Support 3 [+3]
Radiation Tolerance 1000 [+9]
Temperature Tolerance [+32]
Vacuum Support [+1]

You probably also want some DR to avoid repeat "death-stun" by small arms fire and other annoyance.
DR (power modifier, cosmic : +50%; forcefield,+20%; No signature, +20%) [9.5/level]
