Futile Kingdoms doesn't have skills in the sense that other TTRPGs do.
However, many checks and rules do involve a Skill score regarding a specific activity. Such Skills are derived from other stats, often according to specific rules. They are defined where they are needed, for a specific purpose.
Example: Weapon Skill refers to the wielder's skill with his current weapon and is factored into attack and shieldless defense. Each class of weapons is treated a little differently, but usually Weapon Skill is equal to the wielder's Combat Expertise, sometimes with an additional +1 if he has an appropriate Feature: A Level 2 Combat expert / Spearman wielding a spear has Weapon Skill 3.
In less formalized cases, it is up to a GM judgement call based on a character's Expertise and background, according to the following guidelines:
| Proficiency | Skill |
|---|---|
| unskilled, complicated | impossible |
| unskilled, unintuitive | -2 |
| unskilled, intuitive | -1 |
| dabbling | 0 |
| supplementary skill | Expertise // 2 |
| core skill | Expertise |
| specialty | Expertise + 1 |
Typically, adventurers don't have many skills beyond their Major Expertise. But in cases where it can be justified by the background, a generous GM might award a Minor Expertise for the occasion.
