In YGGDRASIL, Players needed to rely on the game's console in order to take out items from their inventory. However, there was no time to do so during a fast-paced battle, the kind where a split second's timing could make the difference between victory and defeat. Hence, a Quick-Change Item is quite useful for players like Ainz who use them to adapt to situations like those.
A Quick-Change Item is used to bring up preregistered items instantaneously in the midst of battle. An example of the Quick-Change are the 15 centimeters long wooden sticks inscribed with the names of various items for later usage.
- According to Volume 5 of the Manga, the wooden sticks Ainz used in his fight with Shalltear Bloodfallen is a prime example of being labeled as such, one of the Quick-Change Items.
- Narberal Gamma’s robe had a quick-change crystal embedded in it, so she could directly swap out her gear for a set of predetermined equipment without having to waste time changing.
