You Summon a Celestial of challenge rating 4 or lower.

The GM has the celestial's statistics.

Harnessing your will's might, you beckon to your patron, successfully summoning and binding one of their celestial aides temporarily. The divine being's aura, almost blinding, emanates a radiant glow before remnants of its otherworldly abode blend into the earthly realm, leaving behind a spectral trace.

Tapping into the profound reservoir of arcane and celestial wisdom within, I extract the incantation. Complex phrases and intricate gestures, born of geniuses from distant realms, materialize. Lowering my hands, I await the grand arrival of the formidable being summoned through the artistry of symbols.
