So, is there anything after you unlock the northernmost part, or that's it, freeplay?
For anyone interested: 'Loyalty' is straightforward; you need 80 to be able to upgrade the girl from cum-bucket/meat-slave employee to 'Advisor'. 'Reason': the lower it is, the more cutie little orkie-pokies they gonna give on each occasion; doesn't do anything else. 'Nympho': the higher this is, the faster she can produce the lil' ones. And that's all they do.
The number of orcs you get from the captured women scale with their level primarily, otherwise. Each one of them has a unique 'talent' (WARLIKE (??? lol), under their profile descriptions), which grants them each something extra: makes them breed faster (faster sessions) / have more little orcs after each session / lets them look for capturable girls faster (advisory advantage) / lets them find higher level girls (each area has an average level for the women that appear there; this makes them slightly higher (with luck)) (advisory advantage) / lets them decrease the orc cost of capturing girls (advisory advantage). Each of these range from LV1 to LV10. All hail the RNGods! xD
Pretty lackluster, if you ask me.
