Countering high acrobatics

[412294]

In the last session I played we fought an enemy with a really high acrobatics check who could avoid all our AoOs, is there any way to stop that from happening?

Not a whole lot. Try to close ranks to force him to tumble through your squares at a higher DC. Use battlefield control spells to make difficult terrain, costing him movement and also increasing the DC. Temporary Str/Dex increases will also increase CMD, as well as other AC boosts.

Bring the fight to them and don't rely on AOOs. The best thing you could do to a highly mobile character is to force them to stand and fight, and the worst thing you could do is spread out and try to play catchup. TOZ's suggestions are on-point.

If you have a grappler in your party, this is their time to shine. Or yeah, a Wizard or Cleric could solve this problem with a spell slot.
