from All Chamber changes coming in VALORANT Patch 5.12 - Dot Esports

Headhunter (Q) 

The spread of the Headhunter’s bullet spray has been increased to reduce spamming and focus on the actual head-hunting part of his kit, rather than players hitting pinpoint accurate body shots. 

• Updated stability curve. 

Rendezvous (E) 

One of Chamber’s anchors has been removed in the biggest hit to his kit yet. Riot has attempted to shift Chamber back to a site-holding sentinel alongside his other counterparts in the class. 

• Chamber places a single anchor that can be teleported to when he’s within the range. 
• The radius of the anchor has been increased from 15 meters to 26 meters.
• Removed teleport activation height restriction. 
• Increased weapon equip time after teleporting from 0.4 to 0.7 seconds. 
• If enemies destroy the anchor, it cannot be used again for the duration of the round. 
• Chamber doesn’t incur a cooldown when he recalls his Rendevous. 

Trademark (C)

Trademark has been changed to act similarly to other semi-global abilities featured in Killjoy’s kit, for example, to include a range restriction. 

• Added a range restriction. It will disable when Chamber moves out of range. 
• Can be recalled mid-round and does not require a line of sight. 
• Added 30-second cooldown on recall. 
• Initial arm time increased from two seconds to four seconds. 
• Health increased from one to 20. 

Tour de Force (X)

The ultimate doesn’t have many changes, but its rate of fire nerf is significant. 

• The fire rate decreased by 57.5 percent. 

Slow effect

The slow changes affect both Trademark and Tour de Force. 

• Slow reduced from 50 to 40 percent. 
• Slow duration reduced from six seconds to four seconds. 
• Reduced slow area of effect radius by 30 percent. 

EDIT: according to RyanCentral on twitter, the new diameter for the tp is 26 meters. Which means the new radius is actually 13 meters. image showing new radius
