i think pseudo c. = pseudo code, supposedly computer languange translated into more understandable english (but cannot be understood by the computer)
also they are saying that if defence reduces damage by a percentage range rather then by a fixed amount range, there would be factors that add to damage before calculating defence and factors which add to damage after calculating defence. im not sure exactly what these factors are but i know that criticals are counted after defence.
anyway, my stats when i killed the silver slime where as follows (4 str from ring):
also, at that same level my bash did about 1.6k damage to slimes, which is clearly much higher then what is shown in the stat window (in that case i had extra +3str (total+7) from ring if i rmb correctly).
i supposed this means that level is taken into consideration when calculating damage...
