I am playing a level 10 alchemist with the confusion bomb discovery, and the saving throw against it is a will throw as it affects the target with confusion spell. So I went to see what the DC of the throw is, and it says:
A saving throw against your spell has a DC of 10 + the level of the spell + your bonus for the relevant ability (Intelligence for a wizard, Charisma for a bard, paladin, or sorcerer, or Wisdom for a cleric, druid, or ranger). A spell's level can vary depending on your class. Always use the spell level applicable to your class.
But they don't say anything about alchemist. I believe it would be intelligence, as I use it for pretty much everything: bombs per day, damage, craft (alchemy), etc. What is the relevant ability for alchemist?
