Davis didn't take it to heart and tried again. Eventually, he did manage to concoct a Crude-Tier Mid-Level Sky Grade Pill.
Tiers indicate a pill's quality in the First Layer. Mainly, there were four tiers.
Crude-Tier, Normal-Tier, Advanced-Tier, and Perfect-Tier.
Crude-Tier pills were pills that lose much of their energy and quality but retain the minimum effect that they were supposed to impart to the consumer.
Normal-Tier pills are pills that have enough energy but not the quality, leading in the pill to be able to have sufficient energy but not able to grant the full effects of the pill to the consumer.
The Low-Level Sky Grade Pill which Davis concocted was of this tier.
Advanced-Tier pills are pills that have both the energy and quality, capable of imparting the consumer with full effects that one could expect from that pill.
Presently, the Crimson Vitality Pill is the only pill of this tier and grade which Davis possessed.
