  • Encourage late-game flexibility by reducing the strength of low-cost reroll playstyles

๐Ÿ“Š Post-Patch Meta & Strategy Tips

Trends You Need to Know

  • 4-Cost Flex Power: With reroll weakened, late-game boards built around 4-cost carries like Yone (Mighty Mech) or Viego (Soul Fighter) are stronger than ever.

  • Artifact Reliance: Soul Fighter Viego thrives with artifacts such as Sniper’s Focus or Wit’s End.

  • Augment-Driven Wins: Augments like Cooking Pot (Bastion Yasuo) and Radiant Refactor (Dr. Mundo) can define top comps, so adapt to RNG offerings.

Recommended Game Plan

  1. Stay Flexible – Scout opponents and pivot off reroll lines when items or augments don’t fit.

  2. Itemization Priorities

    • Mighty Mech: Magic-shred for Karma (e.g., Void Staff) plus tank items for Yone.

    • Soul Fighter Viego: Core of Edge of Night + Jeweled Gauntlet; artifacts like Sniper’s Focus are ideal.

  3. Economy Management – With slower combat pacing, econ augments such as Portable Forge gain value for fast-8/fast-9 leveling.

๐Ÿ”ฎ Community Reactions & What’s Next

  • Player Feedback: Relief over reroll nerfs but some worry about heavy augment dependence.

  • Patch 15.5 Preview: Watch for tweaks to Crystal and potential buffs to underused champs like Smolder.

๐Ÿ’Ž Final Take

Patch 15.4b successfully shifts the spotlight from low-cost rerolls to adaptive late-game strategies. The removal of Socialite and nerfs to Kai’Sa and Jhin open the door for diverse team comps. Flexibility and smart itemization are now key to climbing the ladder.
