How it is counted

Multiplier = product of a support's "X% more/less Damage" and "more/less Attack, Cast or Skill Speed" lines without a condition; a line limited to one kind of damage stays with that kind. Cost = cost & reservation multiplier (GrantedEffectsPerLevel.CostMultiplier). Lines with "against", "when", "for each", "up to"… are listed on the skill pages as conditional.

Assumptions

  • "% increased", crit multipliers and utility (projectiles, chains, area) are not counted.
  • Support pages exist for skills found in Google's suggestions for "poe2 best support gems for …"; every skill gem page has the same block.
