Pulse Trigger

“Thus I bring you death, not by my hand, but by the power of your own creations.” - Archmagus Thulius, the Master of the Arcane before triggering a massive explosion of magical traps

9th Level Transmutation

Classes: Wizard, Sorcerer, Artificer, Bard Casting Time: 1 action
Range: 120 feet (area of effect)
Components: V, S, M (a crystal sphere infused with pure magical energy)
Duration: Instantaneous

Description:

You release a powerful surge of magical energy, triggering the activation of multiple magical items, devices, and traps within a wide radius. These can include enchanted traps, magical grenades, runic explosives, or any other magical device capable of being activated or triggered.

Each creature within the area must make an appropriate saving throw against each magical effect, as determined by the item’s creator or the spell’s description. If a creature fails a saving throw, it suffers the full effects of the triggered item or trap. If a creature succeeds on its saving throw, it takes half damage or avoids the effects entirely, depending on the item’s description.

The pulse is immense, overwhelming even the most potent wards or defenses. Magic-resistant or immune objects may still be affected unless they have specific protections against magic of this magnitude. You can control the timing and sequence of the activations, making the devices go off in the exact order or manner you desire.
