Zack was puzzled as he considered the crystals. Each time he had used one before, it had granted him a substantial boost in experience points, reaching nearly eight million the last time. However, this time was different. When he activated the crystal, he felt a surge, but the increase in experience points was significantly lower than expected.
This unexpected outcome left Zack perplexed. He couldn't pinpoint why the gain had diminished so drastically this time. Was it the nature of this particular crystal? Had something changed in his abilities or the circumstances surrounding its use? The uncertainty troubled him, as understanding the mechanics behind these crystals was crucial for maximizing their potential in future encounters.
