Rain viewed wealth not only in terms of monetary assets but also in broader terms. To him, true wealth included not just riches but also the power to protect, the knowledge to make better decisions, and the strength to face any challenges. He saw wealth as an accumulation of diverse resources that could be used to achieve his goals. The concept of the "Greed Field" intrigued him, but he believed that obtaining this skill would be exceptionally difficult.
Rain's belief was based on his understanding of existing magical systems and his observations of the dragons. He noted that the Kraken dragons had the ability to draw power from certain valuable objects or artifacts. However, he was unaware of any instance where they could harness power directly from individuals. This made him skeptical about acquiring a skill like the "Greed Field" for himself.
