Chapter 7: Spells / Spell Slots

Heightened Spells

Source Core Rulebook pg. 299 2.0
Both prepared and spontaneous spellcasters can cast a spell at a higher spell level than that listed for the spell. This is called heightening the spell. A prepared spellcaster can heighten a spell by preparing it in a higher-level slot than its normal spell level, while a spontaneous spellcaster can heighten a spell by casting it using a higher-level spell slot, so long as they know the spell at that level (see Heightened Spontaneous Spells below). When you heighten your spell, the spell’s level increases to match the higher level of the spell slot you’ve prepared it in or used to cast it. This is useful for any spell, because some effects, such as counteracting, depend on the spell’s level.

In addition, many spells have additional specific benefits when they are heightened, such as increased damage. These extra benefits are described at the end of the spell’s stat block. Some heightened entries specify one or more levels at which the spell must be prepared or cast to gain these extra advantages. Each of these heightened entries states specifically which aspects of the spell change at the given level. Read the heightened entry only for the spell level you’re using or preparing; if its benefits are meant to include any of the effects of a lower-level heightened entry, those benefits will be included in the entry.

Other heightened entries give a number after a plus sign, indicating that heightening grants extra advantages over multiple levels. The listed effect applies for every increment of levels by which the spell is heightened above its lowest spell level, and the benefit is cumulative. For example, fireball says “Heightened (+1) The damage increases by 2d6.” Because fireball deals 6d6 fire damage at 3rd level, a 4th-level fireball would deal 8d6 fire damage, a 5th-level spell would deal 10d6 fire damage, and so on.

Heightened Spontaneous Spells

Source Core Rulebook pg. 299 2.0
If you’re a spontaneous spellcaster, you must know a spell at the specific level that you want to cast it in order to heighten it. You can add a spell to your spell repertoire at more than a single level so that you have more options when casting it. For example, if you added fireball to your repertoire as a 3rd-level spell and again as a 5th-level spell, you could cast it as a 3rd-level or a 5th-level spell; however, you couldn’t cast it as a 4th-level spell.

Many spontaneous spellcasting classes provide abilities like the signature spells class feature, which allows you to cast a limited number of spells as heightened versions even if you know the spell at only a single level.
