House Rules

These are rules changes that either don't fit anywhere else, or I consider specific/fiddly enough that they merit their own page. You can also find these on the IH house rules wiki.

Feats

Power Attack grants +1 bonus to damage per -1 penalty to attacks with a light or 1-handed weapon, or +1.5 per -1 with a 2-handed weapon (rounded down). The penalty is limited to -5 or your base attack bonus, whichever is lower.

Power Attack 4 grants +1.5 bonus to damage per -1 penalty to attacks with a light or 1-handed weapon, or +2 per -1 with a 2-handed weapon. The penalty is limited to -20 or your base attack bonus, whichever is lower.

Combat Expertise grants +1.5 active bonus to defense per -1 penalty to attacks when wielding a light or 1-handed weapon with nothing in the off-hand (not even a buckler). The bonus defense is limited to +5 or your base attack bonus, whichever is lower.

Combat Expertise 5 is the same as Combat Expertise (see above) but the bonus defense is limited to +20 or your base attack bonus, whichever is lower.

Hafted Weapon Mastery when used with a reach weapon removes the -4 penalty for attacking from reach range into a melee. See the Equipment section below concerning reach weapons. When used with a non-reach weapon, it grants that weapon 10-foot reach. In this case, the feat does not remove the -4 penalty.

Combat

Class defense bonus is treated as "always on", much like size and cover bonuses.

There are no size modifiers for grapple checks (whether positive or negative). Big creatures generally have lots of HD (ie, high BAB) and high Strength, which should suffice to represent their advantage in a wrestling match. Note that the size modifiers for regular attacks are not applied to grapple checks, so such creatures have an advantage relative to their regular attacks when grappling.

Equipment

Reach weapons threaten all squares within 10 feet, instead of only at 10-foot range (ie the same as natural reach).

Monsters

Any creature that is not a shapeless blob is vulnerable to flanking and critical hits (including sneak attacks), even if by normal d20 rules it would be immune. This includes plants, (most) elementals, undead and constructs. Oozes retain these immunities.

Constructs and undead gain their Charisma bonus, if any, to hit points. A Charisma penalty does not affect hit points.
