Shield Origamiracle

Fold into Existence. You can use an action to write the word "Shield" on this sheet of paper using any writing implement, in a language of your choice. When you do, the paper magically folds and shapes itself into a small paper shield. While holding the tiny shield, you can use a bonus action to speak a command word and transform it into a strong, full-sized shield made of magically folded and compressed paper. This shield functions as a normal shield in combat. You can speak the command word again to return it to its small paper form. The writing is magically erased from the paper 24 hours after the activation word is written, and the shield reverts to the sheet of paper. If you take 10 or more fire damage in a single round, roll a d20. On a 1, the shield turns to ash. On any other result, it returns to the sheet of paper. Once returned to paper, it can be transformed again after 8 hours have passed.
