Delayed Blast Fireball [SRD5 OGL] [1] [2] (Spell)
Level: 7th-level spell
Class Tags: Sorcerer, Wizard
School: Evocation
Casting Time: 1 action
Range: 150 feet
Components: V, S, M (a tiny ball of bat guano and sulfur)
Duration: Concentration, up to 1 minute
Scales: True
A beam of yellow light flashes from your pointing finger, then condenses to linger at a chosen point within range as a glowing bead for the duration. When the spell ends, either because your concentration is broken or because you decide to end it, the bead blossoms with a low roar into an explosion of flame that spreads around corners. Each creature [3] in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A creature takes fire damage equal to the total accumulated damage on a failed save, or half [4] as much damage on a successful one.
The spell’s base damage is 12d6. If at the end of your turn the bead has not yet detonated, the damage increases by 1d6.
If the glowing bead is touched before the interval has expired, the creature touching it must make a Dexterity saving throw. On a failed save, the spell ends immediately, causing the bead to erupt in flame. On a successful save, the creature can throw the bead up to 40 feet. When it strikes a creature or a solid object, the spell ends, and the bead explodes.
The fire damages objects in the area and ignites flammable objects that aren’t being worn or carried.
At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the base damage increases by 1d6 for each slot level above 7th.

- Rule Tip: You're a Creature. A creature is anything that belongs to one of the creature types listed in the introduction of the Monster Manual (5e). Player characters — including your character — are all creatures, and most of them are humanoids, one of the game’s types. - UA 2020 Subclasses Part 3. ↑
