Rainbow Six Siege Y4S1.3 patch notes: Lion rework drops tomorrow

The latest incoming patch for Rainbow Six Siege will be the the Year 4 Season 1.3 update, and Ubisoft has revealed that it will drop tomorrow – April 16 on PC, with console owners having to wait until the day after.

In preparation for the update, the team has also released the full Y4S1.3 patch notes, which details a bunch of significant changes coming to the game. As has previously been revealed, the biggest update is to Lion’s ability – which is getting a major rework due to player demand. Capitao’s asphyxiating bolts are also getting some changes.

As Ubisoft detailed just last week in the Siege team’s latest designer notes, the much-requested Lion rework is “aimed at reducing the oppressive feeling of his ability while maintaining his intel-gathering role”. His ability warning is decreasing from three to 1.5 seconds, and scanning is dropping from four to two seconds. He also now has three charges instead of two, and his ability cooldown has been reduced from 27 seconds to 15. Furthermore, Virgil’s ERC–7 cloak now makes him immune to Lion’s scan.

As for Capitao, the team are altering his abilities to bring him more in line with his “original intention”, which is area denial. Dart fire damage per tick is reducing from 19 to 12, the area of effect size is increased, and
it takes two seconds to reach maximum size. As Ubisoft notes, “adjustments to his AOE damage will now emphasize skill and not blind luck.”

Other than this, other Siege operators will receive a minor adjustment to their abilities too – although not to the same degree as Lion or Capitao. Blitz’s ballistic shield flash cooldown will increase from 2 to 7 seconds between flashes, Maestro’s Evil Eyes windows will open a little when disabled by EMPs or Shock Drones, and if Echo uses his PDA he can be detected by IQ. For the rest of the changes, check out the full patch notes below or on Ubisoft’s update site.



  • Reduced the ability warning to 1.5 seconds (from 3 seconds).
  • Reduced the scanning to 2 seconds (from 4 seconds).

With more of a focus on intel gathering, now this predator has to play smart to catch his prey. Check out the Designer’s Notes to learn more.


  • Dart fire damage per tick reduced to 12 (from 19/tick).
  • Dart fire AOE size increased and now takes 2 seconds to reach max size.

Enjoy the breather!
