Sorcerer Spellcasting
Level 1
Your bloodline provides you with incredible magical power. You can cast spells using the Cast a Spell activity,
and you can supply material, somatic, and verbal components when casting spells (see _Casting Spells on page 302). Because you’re a sorcerer, you can usually replace material components with somatic components, so you don’t need to use a spell component pouch.
Each day, you can cast up to three 1st-level spells. You must know spells to cast them, and you learn them via the spell repertoire class feature. The number of spells you can cast each day is called your spell slots.
As you increase in level as a sorcerer, your number of spells per day increases, as does the highest level of spells you can cast, as shown on Table 3–17: Sorcerer Spells per Day on page 193.
Some of your spells require you to attempt a spell attack roll to see how effective they are, or have your enemies roll against your spell DC (typically by attempting a saving throw). Since your key ability is Charisma, your spell attack rolls and spell DCs use your Charisma modifier. Details on calculating these statistics appear on page 447.
Heightening Spells
When you get spell slots of 2nd level and higher, you can fill those slots with stronger versions of lower-level spells. This increases the spell’s level to match the spell slot. You must have a spell in your spell repertoire at the level you want to cast in order to heighten it to that level. Many spells have specific improvements when they are heightened to certain levels (page 299). The signature spells class feature lets you heighten certain spells freely.
Cantrips
A cantrip is a special type of spell that doesn’t use spell slots. You can cast a cantrip at will, any number of times per day. A cantrip is always automatically heightened to half your level rounded up—this is usually equal to the highest level of spell you can cast as a sorcerer. For example, as a 1stlevel sorcerer, your cantrips are 1st-level spells, and as a 5th-level sorcerer, your cantrips are 3rd-level spells.
