Skill affinities

Every demon has a skill affinity for each kind of skill: the eight elements, Almighty, Recovery, Ailment and Support. Attack affinities go from -9 to +9, the others from -5 to +5. You see them on the demon's page and in the team builder.

Kind	Positive	Negative
Attack (elements, Almighty)	odd steps +10% damage, even steps -10% MP cost	-10% damage per step
Ailment	+5% chance per step, cheaper	-10% chance per step
Recovery	stronger healing	more expensive
Support	cheaper	more expensive

For example, Matador has Phys +5: its physical skills deal 30% more damage and cost 20% less MP. Affinities do not change the normal attack.
