Valorant Patch 13.08 Notes: Map Rating Arrives, Corrode Reworked, Ascent and Split Leave the Pool

Patch 13.08 kicks off V26 Act 6 with a private per-map rating, a Corrode rework, Bind's return and a fresh look for queue and Career screens.

Valorant Patch 13.08 went live on October 13, 2026, and it opens V26 Act 6. There are no agent or weapon balance changes this time. Instead, Riot has shuffled the map pool, reworked the parts of Corrode that players complained about most, and added Map Rating, a private score that shows how good you actually are on each map.

TL;DR

• Map Rating is new: a private 0–500 score with a C-to-S grade for every map, in Competitive and Premier.
• Bind and Corrode are back in Competitive and Deathmatch. Ascent and Split are out.
• Corrode gets faster defender rotations, a metal Mid wall and a smaller A-site plant zone.
• A new Queue and Mode Select screen, plus a navigation bar in Career.
• Small Killjoy Alarmbot feedback fix and a Warden scope reticle fix.
• Riot published its Act 5 penalty numbers, including more than 171,000 cheating bans.

Map Rating: your personal map report card

The headline feature is Map Rating. It tracks how well you perform on each map over time and turns that into a number from 0 to 500, paired with a letter grade from C up to S.

The rating is built from four inputs:

Recent matches count for more than old ones, so a good week on Lotus will move your grade faster than a slump from months ago would. Only you can see your own rating. It shows up in Agent Select, on the End of Game screen and in Career, which also gets a new navigation bar for jumping between Rank Legacy, Accolades and Map Rating.

Two things to know before you check it. Map Rating only counts Competitive and Premier games, and everyone starts from scratch: no matches from before the patch are counted. Expect your grades to look empty or unreliable for the first few games on each map.

Because Performance Score is one of the inputs, it's worth remembering what 13.06 changed: damage, adjusted kills and adjusted deaths (including first bloods and first deaths) carry more weight, and Chamber has his own adjustments to reflect how his utility is used.

The new map pool

Act 6 brings a two-in, two-out rotation for both Competitive and Deathmatch:

Losing Ascent and Split in the same patch is a big change. Both are classic, mid-heavy maps that a lot of players use as comfort picks. Bind, with no mid and its teleporters, plays very differently, so players who mostly queued for Ascent will need to relearn their habits.

Corrode changes

Corrode returns with a set of changes aimed at its two biggest problems: slow retakes and a Mid that rewarded spamming through walls.

1. Faster rotations for defenders. The paths from defender spawn into the back of both A and B sites have been adjusted, so getting to a retake should take less time.
2. Mid half wall is now metal. It has also moved out about one meter. You can no longer spray through it, and attackers can reach A Link without being seen from Top Mid.
3. Lower Mid boxes moved. The boxes at the back of Lower Mid have shifted toward B and now have a jump-up, giving attackers a new elevated angle. The Lower Mid wall has also been raised to stop players peeking from those boxes.
4. Smaller A-site plant zone. The plant area on A has been changed so that post-plant setups from A Link are less effective.

Together, these changes push Corrode toward a fairer attack-versus-defense balance. Defenders get to retakes faster, and attackers lose an easy lurk-and-spam spot.

Client and quality-of-life updates

• New Queue and Mode Select interface. Both matchmade and custom game types now use a redesigned screen. It follows the merged Home and Lobby hub that arrived in 13.06.
• Career navigation bar. Feature pages like Rank Legacy, Accolades and Map Rating are now easier to reach.

Agent and weapon notes

There's no balance pass this patch, only two small changes:

• Killjoy: The Alarmbot now plays its destruction effects and sound when a projectile is destroyed by a moving doorway. It's purely a feedback fix and doesn't change her power.
• Warden: The scope reticle no longer drifts out of alignment during full-auto fire, a welcome fix for anyone who has been sticking with the new rifle.

Bug fixes worth knowing

• The Masterful accolade showed the wrong threshold. Fixed.
• Alternate footstep sounds sometimes didn't play inside Fog of War. Fixed.
• Bodyfall audio played in the wrong place when agents died in Fog of War. Fixed.
• Gun bounce audio sometimes failed to trigger. Fixed.

Footstep and bodyfall audio matter more than they sound, since they tell you where an enemy is. These fixes are a small but real improvement for competitive play.

Known issues

• Team MVP sometimes doesn't display correctly in Match History. Riot is working on a fix.
• Practice Range while in queue has been temporarily disabled after it left some players stuck in a broken queue state. A fix is being tested, with no return date yet.

Act 5 penalty report

Riot also shared enforcement numbers for bans of three days or longer between August 18 and October 1: more than 171,000 for cheating, 54,000 for botting, 76,000 for rank manipulation, 74,000 for toxicity or comms abuse, 288,000 for repeated AFK or gameplay abuse, and 14,000 for stream sniping or instalock tools. Riot is still asking players to keep using the in-game report button.

What it means for players

Patch 13.08 is a systems-and-maps patch, not a meta shake-up. Your agent picks probably don't need to change, but your map practice does. With Ascent and Split gone and Bind and Corrode back, it's a good week to run a few Deathmatches on the new maps before ranked. Map Rating should also make it easier to see which maps you are actually winning on and which ones you are only picking out of habit. Just give it some time before trusting it, since every grade started from zero this patch.
