Damage stacking

Does glasscannon + push the limit + fire damge increase. Imcreases the damage output of crushing flames?

nothing else affects Crushing Blow or Crushing Flames, except for an enemies Tier Rank. Magic+ Tier enemies reduce the effectiveness of Crushing Blow like this…

Normal - enemy current health x 0.25
Magic - enemy current health x 0.25 x 0.25
Rare - enemy current health x 0.25 x 0.25 x 0.25
Mythic - ECH x 0.25 x 0.25 x 0.25 x 0.25 x 0.25 x 0.25

this is what makes Crushing Flames so useful. the Developers have said that because Crushing Blow is a different type of damage, it isn’t affected by other damage multipliers.

hope this helps.
