Skills
You gain 40 skill points every level, except at character creation where you have 120 points to spend. You cannot increase any given skill beyond its maximum for your current level, which is 10 + 5 per level. This means you can max 8 out of the 22 available skills each level, or split your skillpoints into more skills.
- Related base abilities
- Each skill is affected by one of your character's base ability scores, but the amount of points you may invest in any skill is not restricted by them. Every point in base ability above 4 increases the effective value of dependent skills by 10%, while every point below 4 decreases it by 8.5%.
- Skill synergies
- Some skills also benefit from others through skill synergy, increasing their effective skill level by a percentage of the synergistic skill. Synergies cannot boost skills beyond their maximum for your current level.
