You charge up power in your wielded melee weapon.
Your weapon gains 10 annihilation charges,
+10 more per boost from Intensify,
which last until the end of your next turn and
cause your weapon to shine brightly, casting bright light in a 30 ft. radius, and dim light for a further 30 ft.

You may cast this spell multiple times to charge up additional power.
Each time you do, you gain another 10 annihilation charges,
+10 more per boost from Intensify,
and the duration of your annihilation charges is extended until the end of your next turn.

Counterspell:
This spell cannot be Counterspelled, but it can be Dispelled.

Suggested Backfire: Your weapon shatters.

When you attack with a melee weapon empowered by annihilation charges, you may spend all your annihilation charges to cast Arcane Burst, Arcane Cone, or Arcane Beam including the creature you attacked as a target, without paying their casting cost or spending an action.
That spell deals +1 damage per annihilation charge spent.

You can Intensify these spells.
(You must know the spell to cast it.)

Counterspell:
Spells cast using Annihilate have +15 to the DC to Counterspell them.
