Spellsealer (Patreon)

Weapon (war pick), very rare (requires attunement)

This wicked war pick has been used to destroy a powerful wizard's spellbook. The weapon's surface is marked with abjuration wards to contain malevolent spellcraft. You gain a +2 bonus to attack and damage rolls made with this magic weapon.

Once per turn when you hit a creature with the war pick, you can choose to use either its Read or Seal property.

Read. You magically know the names of 1d4 + 1 different spells that the creature can cast; these are chosen at random by the GM, skipping any that you've already learned using this property.

Seal. You magically prevent the target from casting a spell you name until the start of your next turn. If the creature attempts to cast the spell, it must first make a DC 16 Constitution saving throw. On a success, the creature casts the spell. On a failure, the spell fails, and the action is wasted. Regardless of whether it succeeds or fails, the creature then takes 1d10 force damage.

"Firebaeow!"

"Finger of deaugh!"

"Disintegra—"

CRUNCH.
