A long time
Lex spent quite a lot of time playing- eh, no, designing his next tavern on Mindcraft. But he could not shirk his duties either, since this was his Inn, so Lex relied on a very basic cloning technique he had mastered.
His clones would have a fraction of his strength, and could not go too far from his main body. In fact, their range was limited to the extent of Lex's spirit sense, which was actually quite massive. But, considering his connection and awareness to the entire realm, his clones could go anywhere within the realm itself.
As such, it was no problem having them accompany Ripley as he continued to audit the Inn. Lately, he had been going over the roles of the various staff members and the divisions, looking for inefficiencies or redundancies.
