Just to make a quick recap of the hitpoints and all, we have seen the following in the mean time for hitpoints due to Stamina and level:
HP = TRUNC [ 5 x ND ] + TRUNC [ Lvl x LM x ND / 10 ] + TRUNC [ TRUNC [ TRUNC [ STA - Post-255 ] x Lvl x LM / 3000 ] x ND ]
TRUNC means Truncation occurs for the term between [ ] that follows it.
For the term Post-255 we have
Post-255 = MAX [ 0, ( (STA-255)/2 ) ]
So Post-255 will only be non-zero when STA exceeds 255.
ND is the multiplier bonus they use (Natural Durability, Physical Enhancement, etc ...). LM is a class and level dependent multiplier as indicated below:
