Mind is your top priority, both in primary 'Training' edict tab as well as 'Specialization'. Max up to lv 5 and also get the extra lewd mind edicts. 'Release desires' is obvious but 'Resist orgasm' is a very useful skill, allowing the Warden hold off her cumming when working as waitress so she does not shatter the glassware she's carrying when orgasming and ability to experience double and triple orgasms, which grant her two important passives. 'Edging', not so much, though there are situations when locking the leading partners orgasm gives you a tactical advantage, allowing other participants to catch up with him, so the sex position does not get broken too soon.
The mind edict in Specialization tab that is worth investing in is 'Recovery', which allows the Warden to use mental skills after 'Restore Mind'. Very useful when you want your super slut to remain a technical virgin, so you need to keep her pussy desire in check. Bliss can be a bitch in this regard, so you want her as alert as possible.
Endurance comes second, as it reduces pleasure damage Karryn receives and also increases Stamina, which is important if you want Karryn to be an active slut, not just someone who only passively receives dicks but meets them halfway, just like Black Eyed Peas recommended. Capacity is a Specialization Endurance edict that should be most interesting as it further increases energy.
Then it's agility, which increases initiative (priority of MC's actions vs NPC's). With a super-slut Karryn, the battles may become sex orgies from round one, no need to wait for them to strip/molest her or overpower physically. With enough charm and inmate soft-spot passives, everyone will be horny and erect from get go, just select your favourite position.
As you can only select two specializations, furthering of mind and endurance edicts is the best choice IMO.
Dexterity comes next. It does increase pleasure damage inflicted upon inmates and guards, so not a bad thing, but remember that Karryn has to survive all that debauchery in the first place, so you should concentrate on her being able to withstand all that pleasure regularly unleased upon her before you invest in her abilities to kill with kindness. She can only do one sex move per round, while she has to potentially absorb up to six sex moves from her opponents in normal battle and up to ten in the bar scene (at work and post work).
Strength... you can forget about strength, just as well as combat-related edicts. It is possible to build a pacifist-slut who does not strike anyone and still manages the Prison well.
Then there are accessories and titles, some of them essential must-haves (Purple and Palladium bracelets).
