Fractional DR #1 Class DR (such as barbarian) remains as-is, a flat number subtracted from physical damage taken. #2 Racial DR becomes 30%, rounded down. If you deal 13 damage, it reduces damage by 3.9, rounds down to 3.
Rationale: I'm trying this particular order of operations for speed. The math works out to nearly match DR5 or 10 or 15 at the levels they come available... for typical high output martials (two-handed Power Attacking rage), and much less reduction for less "big hit" builds.

This point-buy is designed to allow multi-ability-dependent classes to be as viable as single-ability-dependent classes. As well, this allows a more "rounded" character, providing enough points for martial characters to invest in diverse skills for instance.
Unless otherwise specified, the Medium XP track is being used
In an effort to make Oracles more viable as cleric replacements without being "healbots", the following spells are added to all oracles' spells-known at the appropriate levels.
A Life mystery oracle's bonus spells granted list swaps in these spells to compensate: shield other (4th), searing light (6th), death ward (8th), hallow (12th), heroe's feast (14th), repulsion (16th), discern location (18th).
