Rules (Apath)

Unofficial rules compendium

Multi Classing

All abilities based on class level are instead based on character level. This applies to what the ability does, not to how you use it (if you can use it, how many times you can use it, or what kind of action it is to use). This increased the utility of multiclass spells, animal companions, and such.

Not affected by this are hit points, base attack bonus, skill points, and saving throw modifiers, and any ability mentioned in the "special" column of the class table with a new entry, which still work per the normal rules. Spells per day and spells known are always determined by class level, but caster level is character level.

Example: Trapfinding improves based on character level, as Trapfinding is only mentioned one in the Special collum of the Rogue's class table. Sneak attack does not improve with increased character level but only with Rouge class level, as each tier of Sneak Attack is mentioned separately.

Skills

Some skills have gained additional uses.

• Acrobatics
• Craft
• Linguistics

Skills can get critical success; on a roll of 20 you can roll again (much like when verifying a critical hit) and of the second roll would have been a success against the DC of the original task, it somehow succeeds spectacularly well.

Increasing abilities

• As long as you use your level-granted ability increase (normally gained at levels 4, 8, 12, 16, and 20) for an ability increase resulting in a score of 13 or less (before racial modifiers), you get two ability improvements, neither of which can give you an attribute score exceeding 13.
• Skill point bonuses are based on permanent, intrinsic Intelligence score. Permanent changes to Intelligence retroactively changes the number of skill points.

Metamagic

Forget the original metamagic rules except when creating magic items.

Applying metamagic is a free action for all classes, and it is never prepared in advance. You can apply metamagic that brings the effective spell level of a spell up to the highest spell level you can cast, for free. You can apply the same metamagic feat several times to the same spell, with cumulative effects.

Improved Critical Feat

The Improved Critical feat stacks with other effects that improve the crit range of a weapon, but other such effects do not stack with each other.

Falling Damage

A character that takes falling damage and does not successfully mitigate at least some of it using Acrobatics or other means falls prone and ends his turn.

Both Acrobatics can reduce damage by more than 1d6; each multiple of 15 on the Acrobatics roll removes another die of falling damage.

Falling damage scales with size; the normal d6s of damage are for a creature of medium size.

Size	Fine	Diminutive	Tiny	Small	Medium	Large	Huge	Gargantuan	Colossal
Falling damage die	1	1d2	1d3	1d4	1d6	1d8	2d6	3d6	4d6
