Hopefully a good necro.
I've got a fairly decent save file with absolutely everything, so here's what I've learnt from save scumming the everliving shit out of everything.
- Jailing does not prevent Pliable
- Sending her out to guild training does stop Pliable
- Recovering from modifications in the laboratory also stops Pliable
- I discovered that it is actually extremely difficult to lower loyalty. However I did find the answer, the spell 'Summon Tentacles', which reduces loyalty by 20 on cast. However...
- If Pliable has turned into Devoted, it is impossible to also gain Slutty via Regression
- However if you get Slutty first, it is VERY easy to get Devoted as well
So, if you want Cali to be Slutty, DON'T start her questline until after you get that spell. Or, be sure you have her constantly in training or undergoing recovery until you can blitz her loyalty with some tentacle sex.
