Volatile Blast

You enchant two objects within range with energizing magic that violently reacts on physical contact with each other. The affected objects have a linking magical aura, but is visually unaffected.

The objects must not be larger than 5 feet in any direction, and must not be in contact with each other at the time of spellcasting. Surfaces (walls, floors, ceilings) cannot be enchanted.

Upon physical contact of both objects, a bright blast originates from the contact point in a 5-foot radius. All objects within the radius takes 1d8 fire damage, and creatures affected must succeed a Dexterity saving throw or also be damaged. The noise of the blast can be heard from up to 200 feet away unless obstructed. Depending on the proximity to the explosion or other factors, the GM may also choose to include additional effects such as knockback, fire spreading, etc.

Once per turn, you may spend 1 action to transfer one of the explosive enchantments to another valid object.

The effect ends when the blast is activated, when either enchantment is dispelled, when you recast Volatile Blast, when another creature casts Volatile Blast onto your already enchanted object(s), or when you remove the enchantments prematurely.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by an additional 1d8 for each slot level above 1st. Additionally, the blast radius increases by 5 feet when upcasted for every two levels above 1st.

"Indeed, the wretch is now naught but ash... but did you really have to cast that on his underwear and trousers?"
