Here are the full Dota 2 Patch 7.33b notes
Less than a week after Dota 2’s massive New Frontiers update dropped on April 20, Valve followed it up with another one, Patch 7.33b, on April 25 to iron things out and fine-tune others in time for the Berlin Major.
In addition to making Tormentors ignore illusions and reworking some natural creeps, neutral items, and actual items, the patch also changed quite a few heroes. The biggest ones include nerfs to Riki, Phantom Lancer, and Void Spirit—all of which have been a little too strong in the early stages of the new meta.
