How it is counted
Which supports fit Eye of Winter: the game's skill types with Path of Building's rules (the full list). Multiplier = product of the support's "X% more/less Damage" and "more/less Attack, Cast or Skill Speed" lines; a line limited to one kind of damage (physical, hits, poison magnitude…) is kept to that kind. Cost = the support's cost & reservation multiplier (GrantedEffectsPerLevel.CostMultiplier).
Assumptions
- "% increased" lines, crit multipliers and utility (more projectiles, chains, area) are not multipliers here: their worth depends on your build.
- A multiplier for physical damage only helps the physical part of Eye of Winter's damage, and so on for each kind.
- Read the "also" lines: some supports add a cooldown or a cost in Glory or Combo.
