Skill Cost modifiers

• Most skills need PP to cast. The following table lists all game mechanics which affect skill PP costs. Since cheaper skills are better, for this table, negative values are better than positive ones.
• Amounts for Skills are affected by S, the number of skill points invested in the skill.
• A maximum of -5 can be applied to Skill Cost; any modifiers above that are ignored.
