Alignments
There are no alignments. Any spells with an alignment subtype do not exist. Damage Reduction X/Good or Evil becomes Damage Reduction X/Silver. Damge Reduction X/Lawful or Chaotic becomes Damage Reduction X/Cold Iron. Abilities such as Smite Evil now work on everyone.
Ability Score Increases
4th level +1 to two scores
5th level +1 to one of your three lowest scores
8th level +1 to two scores
10th level +1 to all scores
That repeats, so 15th level and every 10 levels after will be +1 to one of your three lowest scores. 20th level and every 10 levels after will be +1 to all scores. If two ability increases fall on the same level (such as 20th), you get both.
Natural Healing
8 hours of rest heals your character level plus your constitution modifier in hit points. This is doubled as normal for 24 hours bedrest.
