I have a question about a character concept I have. I'm picturing a Tiefling with the oversized limb variant ability ("You have oversized limbs, allowing you to use Large weapons without penalty.") I would combine this with the Titan Fighter archetype which at first level can wield giant weapons. ("At 1st level, a titan fighter can wield two-handed melee weapons intended for creatures one size category larger than himself, treating them as two-handed weapons. He takes an additional –2 penalty on attack rolls when using an over-sized two-handed weapon.")
Does this mean the character would suffer no penalties if it wielded a large sized 2-handed weapon? The Titan Fighter class ability allows hime to wield large sized 2-handed weapons and the oversized limbs allow him to use large weapons without penalty. Do these abilities stack so that a medium sized Tiefling Titan Fighter with oversized limbs can wield a large sized Earth Breaker without any penalty?
If they don't stack then the oversized limbs would give no benefit over any other Titan Fighter.
