After training my {Blood Enhancement} trait to increase its level inside my dorm, I discovered two significant drawbacks through experimentation.
The first drawback was duration dependency. The enhancement's lasting power directly correlated with both the quantity and quality of blood used. Elite-rank blood maintained the enhancement for extended periods while providing stronger overall effects. Noble-rank blood, by contrast, offered shorter duration and weaker enhancement benefits.
The second drawback related to equipment rank. Higher-ranked items required substantially more mana investment to maintain the enhancement effect. It operated like a transaction system, I had to spend mana to extract enhancement benefits from the blood. Once the blood was exhausted, additional mana input became irrelevant.
