Critical Missile + Vulnerability Fated Ashes Build
Patch 16.13 ARAM Mayhem Critical Missile + Vulnerability guide centered on Fated Ashes, full crit, missile procs, risks, and bug fixes.
Patch 16.13 Role of the Fated Ashes Missile Build
In patch 16.13 ARAM Mayhem, this missile build should no longer be framed only as an old Statikk on-hit setup. Current data puts 
Critical Missile in T1 at about 62.7% win rate, while 
Vulnerability sits in T3 at about 50.6%. The updated route uses Fated Ashes, full crit, and both Gold augments to turn repeated crits into steady missile procs.
Core Mechanic: Fated Ashes feeds more missiles
Vulnerability lets item effects and damage-over-time crit, adding 25% crit chance. Critical Missile fires extra missiles on crits and also adds 25% crit chance. Fated Ashes burns in repeated ticks, giving Critical Missile more chances to fire as soon as you buy it.
| Component | Recommended pieces | Purpose |
|---|---|---|
| Core augments | Vulnerability, Critical Missile | One enables DoT crits; the other turns crits into missiles. |
| Trigger source | Fated Ashes | Repeated burn ticks make the missile chain denser. |
| Crit base | Full crit, Infinity Edge | Improves proc stability and missile damage. |
Augment, item, and training priorities
If Vulnerability or Critical Missile appears early, lock it first in most games. Build toward full crit, then add Fated Ashes triggers. Infinity Edge raises crit value, Lord Dominik’s Regards handles armor, and Mortal Reminder fits heavy healing. For training, prioritize omnivamp and move speed before magic penetration, resists, or health.
| State | Recommended call |
|---|---|
| Both core augments | Push full crit and Fated Ashes triggers. |
| Only Vulnerability | Item DoT is fine, but missiles are missing. |
| Only Critical Missile | Needs normal crit, attack speed, and hit frequency. |
| Neither core augment | Do not force the missile build. |
June 26 bug-fix notes
The June 26 fixes mainly affect abnormal interactions and match quality, not recommended play. Poro Stampede with Poro-Snax loops, Spirit Bomb with repeated Kaenic Rookern buy/undo triggers, Dimension Shift visual leftovers with Varus, and Locke R focus-point issues should all be treated as bugs to avoid.
Risks and tradeoffs
The Fated Ashes missile build needs time, item slots, crit chance, and safe uptime. If your team lacks a front line or enemy burst kills you before the chain starts, buy survival and normal damage first. The old Statikk route remains a backup idea, not the center of this update.
FAQ
Q: What is the core mechanic of the Fated Ashes missile build?
Vulnerability lets item and repeated damage crit, then Critical Missile turns those crits into missiles. Fated Ashes adds repeated ticks, making procs denser.
Q: Should you take Vulnerability or Critical Missile early?
Usually yes. The build depends on both core augments, so locking one early lowers the risk of missing the pair.
Q: Why are Blade of the Ruined King and Statikk no longer first?
The update values full crit and repeated Fated Ashes ticks more. Blade and Statikk still have on-hit value, but they are no longer the core trigger source.
Q: Do the June 26 fixes change the build?
No. The fixes target abnormal loops, visual leftovers, and targeting issues. The playable build still centers on Vulnerability, Critical Missile, Fated Ashes, full crit, and safe uptime.
