The script restores health. Not immediately, but little by little and in small portions. Excruciatingly slow, but helps to survive. The hero bleeds during recovery. HORROR!!! But believable (relatively).
Initially, Dim's Zet's script reduced the health of the wounded. I didn't like it. With my killer weapon.dat - i.e. increased weapon damage, Claude is dead like a fly. Altered builder in regeneration.
