Kill a Caelid/Dragonbarrow boss sorcery only

To complete this square, you must defeat a boss in Caelid by using only sorceries. Any boss in Caelid or Dragonbarrow counts for this square, as long as the only source of damage to the boss are sorceries you cast. Spirit Summons are not allowed, nor are NPC summons, incantations, and weapons.

There are a few good options for this square, but realistically you need to make sure you have enough Cerulean Flasks to deal damage enough to kill the boss. Therefore, bosses with large amounts of HP are not advisable.

Sorceries are randomized by the weapon randomizer, so it may be necessary to take multiple checks in order to find a sorcery that is viable. That makes this square synergistic with Learn 10 Sorceries.
