Verified November 6, 2026 · Status: live
LoL ARAM Mayhem’s set-bonus system groups augments into synergy sets that grant tiered bonuses at 2, 3, and 4-piece — introduced in Patch 26.3 and similar to TFT traits, with specific sets like Make it Rain, Archmage, Deathknell, and High Roller receiving ongoing tuning through 2026. Make it Rain’s Patch 26.3 cut from 30/50/100% to 15/30/50% is the headline balance change. Verified on 6 November 2026.

How set bonuses work
When you pick multiple augments from the same set:
- 2-piece bonus. Smallest tier — minor effect.
- 3-piece bonus. Mid tier — notable boost.
- 4-piece bonus. Top tier — game-changing effect.
Players draft 4 augments total (levels 3, 7, 11, 15). Hitting 4-piece on a set requires all four picks from the same set — a strong commitment.
Set examples
- Make it Rain. Gold / resource generation theme.
- Archmage. AP / spell-based theme.
- Deathknell. Execute / assassination theme.
- High Roller. Random chance / critical theme.
Each set rewards specific playstyles — Make it Rain for gold-reliant champions, Archmage for AP mages, etc.
Patch 26.3 — set bonuses introduced
Patch 26.3 launched the set-bonus system. Specific changes:
- Make it Rain. 2/3/4-piece rewards 30/50/100% → 15/30/50% (balance cut).
- Archmage. Set rewards tuned.
- Deathknell. Set rewards tuned.
Patch 26.3 also introduced augment synergies similar to TFT traits — a design pivot toward more mechanical depth.
Patch 26.4 — High Roller tuning
Patch 26.4 followed up with High Roller set adjustments. Specific numbers are in the patch notes but the trend: Riot tightening set bonuses after early overpowered combos.
Drafting for set bonus
Three strategies:
- Commit to one set. All 4 augments from the same set → 4-piece bonus. Highest reward, lowest flexibility.
- Split between two sets. 2-piece on each → double 2-piece bonuses. Lower per-set reward, more flexibility.
- Prismatic flex. 1-2 Prismatic standalone + 2 same-set → 2-piece bonus + Prismatic power. Balanced.
Impact on gameplay variety
Set bonuses increase strategic depth:
- Player must evaluate per-augment power AND set synergy.
- Drafting from higher tiers (Gold, Prismatic) weighs against set commitment.
- Champions favor specific sets (AP champs → Archmage; execute champs → Deathknell).
