I tried to create a kit for this once in DND 2e, and I basically just kept coming back to the point that Seductress of more of a behaviour than an actual class or archetype. Unless the seductress has a goal like thievery, assassination or espionage then she is just having sex with others. That said, I felt it was better just to build the the ability to seduce into various kinds of rogue characters, and it is essentially the same thing with Pathfinder.
Maybe look into some archetypes or prestige classes like spy or master spy, but mostly the class of seductress is not really a class.
In terms of a magical seductress, isn't that just an enchantress?
I don't actually play, I use the formula for creating characters for writing in fantasy settings, and I find it is a pretty decent system. That said though I am not so much about point builds and more about flavour, so I tend towards rogues and bards.
Ked is fast, stealthy, and likes cutting stuff. Sure, like most goblins, Ked likes fire, but he really likes blood. Why? "Because it's such a pretty color, and tasty, and it sprays so much when you cut right here or there."
Ked is dang near invisible when he wants to be, and has been a scout for as long as he can remember.
He's pretty sure his knives have been talking to him, telling him to paint them red, or that he's secretly a person in a human's game, or that plums are the heart of trees, that elephants are actually giant vehicles being driven by halflings, that his uncle Vroot was really Pazuzu on a sick day, or that he should plant flowers inside of the chests of dwarves after he stabs them to make sure they don't get back up... and many other things, but nobody else believes him when he tries to tell them.
Color Thief (Racial - Goblin) - Your skin is an odd tint that somehow absorbs background colors. Maybe because your mother drank a lot of potions when you were still inside her belly. Maybe because you’ve been blessed by the barghests. Maybe because you’re just better than the other boring goblins.Benefit: You gain a +2 trait bonus on Stealth checks, providing you wear only light armor or no armor.

Feats ___________________
Weapon Finesse:
Weapon Finesse: You are trained in using your agility in melee combat, as opposed to brute strength.Benefit: With a light weapon, elven curve blade, rapier, whip, or spiked chain made for a creature of your size category, you may use your Dexterity modifier instead of your Strength modifier on attack rolls. If you carry a shield, its armor check penalty applies to your attack rolls. (Level 1 Commoner Bonus Feat)
Roll With It:
Roll With It: You know how to take a hit, even if your reaction sends you bouncing and flying out of battle while shrieking at the top of your lungs.Benefit: If you are struck by a melee weapon you can try to convert some or all of that damage into movement that sends you off in an uncontrolled bouncing roll. To do so, you must make an Acrobatics check (DC = 5 + the damage dealt from the attack) as an immediate action. If you succeed in this check, you take no damage from the actual attack but instead convert that damage into movement with each point equating to 1 foot of movement.
For example, if you would have taken 6 points of damage, you would convert that into 6 feet of movement. You immediately move in a straight line in a direction of your choice this number of feet (rounded up to the nearest 5-foot-square), halting if you reach a distance equal to your actual speed. If this movement would make you strike an object or creature of your size or larger, the movement immediately ends, you take 1d4 points of damage, and fall prone in that square. This involuntary movement provokes attacks of opportunity normally if you move through threatened squares, but does not provoke an attack of opportunity from the creature that struck you in the first place.
You are staggered for 1 round after you attempt to use this feat, whether or not you succeed. (Level 1 Feat)
