Chapter 408 Let There be LIGHT
Kat and Kamiko quickly fell into an easy system when it came to testing items using the knowledge, they'd gained on their first day. The start was to go with the obvious, whatever that might be. Swinging swords, hitting things with staves, wearing the various items of clothing or pushing energy into the item if there was no other obvious thing to do.
If none of those yielded any results, they'd move onto the second sweep of testing. This involved saying various words hoping to hit upon a common key phrase, looking for hidden switches to activate things, or much to Kamiko's distaste, hitting Kat specifically with the item in question just in case it can only activate on living targets.
