Pathfinder: Wrath of the Righteous · Mythic ability: spellcasting
Improved Abundant Casting
Adds four daily casts each for 4th-, 5th-, and 6th-level spells and lists Abundant Casting as its prerequisite.
How it works
The guide explicitly lists Abundant Casting as a prerequisite, then grants four more spells per day at each of levels 4, 5, and 6. The excerpt places mythic abilities at odd-numbered mythic ranks. It does not specify how the additional uses are divided among multiple class or mythic spellbooks.
