Weaken: % chance to do more damage. 100% or higher (200% cap), all attacks cause Weaken. affects damage at the Element damage level after Resist Element, Greatly Resist Element, Immune to Element, and Effective against Element. more Weaken means more damage! Weaken also works with Arcane Element.
Effective Mythic: all attacks do +25% Effective damage. is affected by Greatly Resist Element and Immune to Element.
Ignore Resist: cancels Weaken and Effective, and also cancels enemies Resist Element, Greatly Resist Element, and Immune to Element.
Weaken +30% vs Enemy Resist (each map gives enemies 50% resist to the maps element).
(1 x 0.5) + 0.3 = 0.5 + 0.3 = 0.8. 30% of your attacks are doing 80% damage and 70% are doing 50% damage.
Weaken +30% vs Greatly Resist Element (reduces damage of one Element by 75%) (higher Tier monster might have up to all 5 Greatly Resists).
(1 x 0.25) + 0.3 = 0.25 + 0.3 = 0.55. 30% of your attacks are doing 55% damage and 70% are doing 25% damage.
it’s possible for you to be on a map with monsters Greatly Resisting the Element that is Effective against them.
Weaken +30% vs Immune to Element (enemies take ZERO damage from their maps element).
(1 x 0) + 0.3 = 0 + 0.3 = 0.3. 30% of your attacks are doing 30% damage and 70% are doing 0% damage.
Weaken +30% with Effective Mythic vs Greatly Resist Element.
(1 x 1.25 x 0.25) + 0.3 = 0.3125 + 0.3 = 0.6125. 30% of your attacks are doing 61% damage and 70% are doing 31% damage.
Effective Mythic vs most monsters.
1 x 1.25 = 1.25. attacks against monsters without Greatly Resist or Immune do 125% damage.
Greatly Resist with Effective Mythic example: Ice is effective against Fire. on a Fire map, any monsters with Greatly Resist Ice will take 31% damage. 1 x 1.25 x 0.25 = 0.3125. Effective Mythic also works with Arcane Element.
Ignore Resist: all attacks do 100% damage. Resist, Greatly Resist, and Immune are ignored. this is why Weaken & Effective Mythic don’t work with Ignore Resist.
a Crystal +90% Weaken takes up 1 space and gives 90% of your attacks +90% damage.
Weaken +100% to +200% takes up 2 or more spaces. every attack takes Weaken damage.
Effective Mythic takes up 1 space giving you +25% damage to all attacks, but takes a big hit against monsters who Greatly Resist their Effective Element. this is usually your Epic+ monsters.
Crystal Weaken +90% and Effective Mythic takes up 2 spaces, more if you want higher Weaken.
Ignore Resist takes up 1 space. although you don’t get any improved damage, you don’t have to worry about reduced damage from enemy Element Resists or Immunity.
I usually either go with +120% Weaken or Ignore Resist, depending on the space requirements of my Build or Build Requirements. I have only recently thought of using Effective Mythic with Weaken, but that means either going down to +90% Weaken with Effective Mythic to stay at 2 spaces, or take up 3 spaces with Effective Mythic and +120% Weaken.
hope this helps.
