In a battle with some Nagas I used the "Imprint Grimoire" ability to steal a shaman spell for a fight. I used that spell in order to summon a storm blight. Now, two hours later and several days of time passing in the game, the storm blight is still following me around as a summoned creature. Even stranger, when I'm on my ship and only have the main character in the party, the storm blight still follows me around. While this would be a cool bug typically, as it gives me another "person" in the party to help with battles, it's now become a game breaking issue. I'm in the gullet and I can't leave the area. This is because I can't get all 6 party members close enough to either exit to actually use it. I'm looking at losing over 2 hours of play time to go back to before I summoned the storm blight. I'd rather not do this but I don't know of anyway to desummon the stupid thing. Any help would be appreciated. Thanks!
