As an hour passed, Rose summoned her artifact again. "Adeat," She says as the slot machine's sent flying out again. "Now give me card 01, Gatling Tarot," She asks as it sends out Card 2, Real Vision.
"W-what? Are you broken?" She asks, shaking it slightly. "Did I do something wrong~~~?" She whines. Then thinks about what happened. "No... the cards are randomized!" Rose figured it out, as the screen glows.
"Good job, you unlocked Card 3, Ray." It says.
"So the more knowledge I unlock, the more cards I get? There's most likely a limit... Also, it could be safe to assume some are unlocked by my increase of strength." She nods to herself.
