Divine Power
Source
Pact Worlds pg. 184
Your divine connection continues to grow, allowing you to use more powerful magic. Once per day, you can cast the 3rd- or 4th-level spell of your chosen connection as a spell-like ability. At 16th level, you can use this ability twice per day, and at 20th level, you can use this ability three times per day. The save DC of these spells is equal to 10 + the spell’s level + your key ability score modifier.
