So, i was looking over 'Remote Bomb' for the alchemist and noticed that the DC to remote detonate is 'INT check of DC 20 +1/ten feet'. Now, my understanding of, and what i have been told by just about everyone, ability checks is 1d20 + ability mod, which would mean that if i were lucky enough to get a 20 INT, i would need to roll a 15 to detonate adjacent to my bomb.
In the Core Rulebook, the only place 'Ability Checks' show up is on page 15, under 'Ability Scores', read as follows.
"While a character rarely rolls a check using an ability score, these scores and the modifiers they create, affect nearly every aspect of a characters skills and abilities. Each ability score generally ranges from 3 to 18, although racial bonuses and penalties can alter this."
This implies that it is the ability score, not the ability modifier that is used.
'check using an ability score...ability score ranges from 3 to 18...'
Any answer would be extremely helpful.
