Child skills are skills that do not level up directly, but instead are leveled through calculating the average of two skills called parent skills. These skills still give bonuses and behave similarly to regular skills in many ways.
- Smelting is the first child skill, which help you smelt faster and get more resources per smelt.
- Calculating the average means that (skill 1 + skill 2) / 2 = child skill. If repair = 50 and mining = 100, smelting would be 75.
