Per page 147, Biotics have a standard regeneration rate of 1D6 M.D. per MELEE ROUND. Pretty self-explanatory. Now, goto page: 84
Regeneration: Basic - 3D4 per HOUR
Regeneration: Enhanced - 1D6 per MINUTE
Both of these state that a Biotic can get these at the listed cost, but their natural rate of regeneration is BETTER. So why would a Biotic bother with these?
The only available Regeneration enhancement that is better than what the Biotic gets is:
Regeneration: Super at 2D6+3 per MELEE
In my mind, as a GM, a Biotic should not need to pay for Basic and Enhanced just to get Super. So as I was making an NPC for someone, I only "charged" the Biotic the 30 Bio-E for Super and not 15 for Basic and Enhanced.
Does this sound right?
