Most 'Bimbo' builds I'm aware of focus on getting
Fuck Sense, which allows substituting Libido for Intelligence.
1. It only substitutes when Libido is higher, so it's never detrimental.
2. It can't go over your cap, no matter how high your Libido is.
3. As far as I know, it only works for Class Perks. Event-based Intelligence checks still run off of actual Intelligence.
If you dump Intelligence, you probably also want Sexy Thinking for the extra Sexiness. Or you can get Dumb4Cum. (increases Max Intelligence. but decreases it and grants Ditz Speech over time. Lost Intelligence is restored & Ditz Speech removed on drinking cum. Currently bugged, doesn't decrease Intelligence properly, leading to unbounded Intelligence gain. Still doesn't break the cap.) The interaction with Ditz Speech can be handy because you can't interact with Bianca or Submit to Lund with it.
Otherwise, it's a standard Tease build. Max Libido & Sexiness, grab as many
Pheromone Perks as you can. You probably also want an alternative Tease Attack (Milk Squirt/Myr Venom/Dick Slap). You also probably want Energizing Libido (includes Amazonian Endurance's prevention of Energy loss on orgasm, doesn't require it or the Amazon Treatment in general). Maxing Inhuman Desire might be a good idea, since your passive Lust gain will be very high, but it's kind of involved. It's possible to get +90 with drawbacks. You have to do things in a specific order, though.
Smugglers & Tech Specialists are probably the best for Tease builds. Sexiness armor is generally high Evasion and Tech Specialists don't actually care much about their armor.
Status matters now. Paralyzed & Tripped targets take 125% Tease damage, Stunned take 25%. While there is a 50% penalty for Teasing while Blind, there doesn't seem to be any malus for Teasing a Blind target. (Oversight?) Likewise, a Smuggler can Tease at full effectiveness with an active Stealth Field. Be the Sexiest Ghost Ever.
Interestingly, this means changing the Heavy Slut Ray to Psionic might have been a net buff; it doesn't reduce it's own damage.
Don't forget a means of attack for things that can't be Teased into submission!
