So everyone will be jumping into action here! Jinwoo will call out his stronger shadows to try to stop the (I assume very heavy stone) door, Hollow and Iron. If need be he'll also lend his strength but since he's not as tall as they are he'll probably have to use his "Dominator's Touch" ability (basically powerful telekinesis that takes the shape of an invisible hand that shadows his movements), which will keep him/his arms occupied.

Hijikata will be trying to ensure everyone inside- Addi, the twins -get out safely!

Meanwhile, Addi (closest to the door) will cast a 3rd level spell- "Enhance Ability: Cat's Grace" -to buff Lyney and Lynette's speed.

Lyney and Lynette will try to grab the parchment from the chest before they book it out!

Do we succeed? :D
