Skill Descriptions
Skills in Blue Sphere

Overview

Skills are the backbone of character growth. By spending Skill Points (SP) earned through battle, you acquire and level up skills — each of which raises specific character parameters and can unlock powerful abilities or even crafting opportunities.

Beyond stat gains, skills serve as prerequisites for unlocking Item Creation (IC) Skills and Field Actions. Some of the most impactful movement abilities — Dash, Float, Swim — are gated entirely behind skill levels. If those are your goal, build toward them early.

⚠ BUILD WARNING — BEFORE SPENDING SP
The order in which you level skill categories has a permanent and irreversible impact on final HP and MP. A Battle-first build locks in 744 HP / 302 MP, while a Knowledge-first build yields 513 HP / 591 MP. There is no way to undo this. Decide your role — fighter or caster — before you spend a single SP.

Category Opposition

Skills are divided into four categories. No one character can master all skills — leveling one category suppresses the opposing side of the skill graph.

◈ Sense

The skill difficulty (1–4) determines how strongly a learned skill suppresses the opposing category. Higher difficulty skills have greater suppression impact — plan accordingly.
