Trap Spotting twice or thrice? Slayer, Rogue, Sleepless Detective.

[Richard McGuffin]

If a character has enough levels in Rogue and Slayer the character could potentially select Trap spotter twice and get the same effective benefit again from sleepless detective. So the question is how many times would the GM have to roll? just twice or it is three times?

Rogue Talent: Trap Spotter (Ex)
Benefit: Whenever a rogue with this talent comes within 10 feet of a trap, she receives an immediate Perception skill check to notice the trap. This check should be made in secret by the GM.

Sleepless Detective:Eye for Detail (Ex)

At 4th level, a Sleepless detective's keen eye for detail helps her notice hidden traps, doors, and clues. The detective is entitled to an immediate Perception check to notice such features whenever she passes within 10 feet of them, whether or not she is actively looking. This check should be made in secret by the GM. If the detective would already receive such a check because of an ability from some other source (such as the trap spotter rogue talent), the GM should roll the Perception check twice whenever the Sleepless detective is within 10 feet of a trap and use the higher result.

While a character can multiclass with these parent classes, this usually results in redundant abilities. Such abilities don't stack unless specified.

A rogue cannot select an individual talent more than once.

The Rogue+Slayer wouldn't work but the other one would stack.

By that logic doesn't that mean a Slayer who choose Ranger combat style at level 2 doesn't get the benefit of a Ranger Bonus Feat when he later takes two levels of Ranger?

I'm not really convinced this particular example of slayer rogue would result in a "redundant ability" either.

Would the same happen in a Investigator/Slayer combo? There would be no parent class to conflict with and each time the character selects the option it is coming from a different class. So no I don't see it as the character selecting the same talent more than once. It would be Slayer talent, Rogue talent, Investigator Talent.

If you choose the same feat.
