Dagger Origamiracle

Fold into Existence. You can use an action to write the word 'Dagger' on this paper using any kind of writing implement, in a language of your choice. When you do, the paper magically folds and shapes itself into a small paper dagger. You can use a bonus action to speak a command word while holding this tiny dagger to turn it into a strong, full sized dagger made of magically folded and compressed paper. This dagger functions like a normal dagger in combat, but you may speak the command word again to change the dagger back to its small paper form.   The writing is magically erased from the paper after 24 hours have passed since you wrote the activation word, the dagger then turns back into a single sheet of paper. If you take 10 or more Fire damage in a single round, roll a d20, on a 1 the dagger turns to ash, on any other number the dagger turns back into a single sheet of paper. After it is turned back into a single sheet of paper, it can be transformed again after 8 hours have passed.
