Yes, it provides reference tables and benchmarks for HP, AC, and damage output to help you align your creature's power level with a specific Challenge Rating.

How do I customize a monster's fighting style?

The skill offers specific ability score distributions for different roles, such as Brutes (high STR/CON), Skirmishers (high DEX), and Casters (high mental stats).

What ruleset does this skill follow?

The skill follows the System Reference Document 5.2 (SRD 5.2) standards, which are widely used in 5th edition d20-based tabletop roleplaying games.

Can I use this for non-combat NPCs?

Certainly. While it excels at combat stat blocks, it includes templates for NPCs that focus on ability scores, skills, and languages for social or environmental encounters.
