You have Stone Gauntlets in the Cube.
Getting hit increases your armor by 50%, but reduces your movement speed by 15% and attack speed by 20%. This effect stacks up to 5 times.
So, at 5 stacks your movement is slowed by 75% and your attack speed is reduced by 100%. To prevent the slowing effects, you need to do one of these things…
- Maintain 100% up-time on Wrath of the Berserker
- Wear a rank 25+ Invigorating Gem (immunity to control impairing effects)
- Wear or Cube the Ice Climbers boots (immunity to Freeze and Immobilise effects)
There are better suggestions for items to have in your Cube, especially for Season 20. For more details check…
