From 5E to Pathfinder

OK, here’re a few abilities (2 feats and a rogue talent) that I came up after running D&D Next Playtest for my players. These were aspects of the (potential) new edition that I particularly enjoyed and that I guess can also be easily inserted in Pathfinder.

Slayer [Combat Feat]

You execute your attacks with extra force and brutality. Even if your enemies avoid your main strike, they suffer minor cuts and bruises.

Prerequisite: Str 13, Power Attack, Cleave, Fighter 2^nd level

Benefit: You can, once per round as an immediate action, after failing a melee attack, deal your Strength modifier in damage against that target. If you choose to use this benefit, you suffer a –2 penalty to your AC until the beginning of your next turn.

Researcher [Feat]

You are not only an erudite, but also know many sources of mundane and eldritch knowledge.

Prerequisite: Int 13, Trained in 3+ Knowledge Skills

Benefit: If you fail a Knowledge check, you know at least one place where to get the information sought. This can be a person, an item or place (chosen by the Gamemaster).

Skill Dominance [Rogue Talent]

You failure seem certain, you can fall back to your experience, instinct or just blind luck.

Benefit: You can, once per day, after rolling any Skill check, but before knowing if it succeeded or failed, treat the result as if you had rolled a '11' on the d20.
