Travis kept up the use of his manalysis while he and Felix past the time through chess. Every turn he took, he took the brief moment to gaze at Felix's mana flow and then turned his attention to the mana crystal powering their spell. About an hour of doing this routine, he began cutting back the need to check on the Magi having concluded that the spell was performing as expected, as long as it had a flow of mana energy to consume. 

Another hour had passed and their spell had given out, due to the mana crystal it was pairing with having run dry. With their test complete, it was evident that they had no need to linger further seeing as Felix's condition becoming more apparent now. Travis rose from his seat, almost immediately as Felix recalled the chess set and furniture back into his inventory before processing to follow him back into his portal, back to the mansion.

"Now that we know that our rune can function for awhile," Travis began, "we'll certainly need to address power source problem and come up with an efficient solution if you're going to be operating outside the mansion for far longer than 2 hours."
