The Pathfinder Playtest for 2E has the following in the section about ability scores:
When your character advances to 5th, 10th, 15th, and 20th levels, she receives ability boosts in four different ability scores. These function similarly to the ability boosts she receives at 1st level, but she is free to use them to increase her ability scores above 18.
There are two ways to read the first sentence:
- At 5th level, you gain four ability boosts. Then at 10th level, you gain four new ability boosts, etc.
- At 5th level, you gain one ability boost, and one at each 5th level afterward. This adds up to four different ability boosts.
Which is the correct reading? Is this just a case of an unfortunate coincidence in the number of times ability boosts are awarded, or are there only four ability boosts to be had? I checked the Paizo blogs and here, as well as the section about character advancement in general, but no dice.
