Situational item swaps (explicit):

  • Mortal Reminder vs high-heal champions

Build divergence notescross-source synthesis

Both aggregators merge Rhaast and Shadow Assassin into one build — note that the Royal 7.1e analysis above proposes a separate Manamune build for Shadow Assassin post-buffs that neither aggregator surfaces yet (likely lagging behind the new patch's optimal line).

Consensus across both aggregators

  • Keystone: First Strike
  • Core items: Youmuu's Ghostblade → Berserker's Greaves → Eclipse → Duskblade of Draktharr (all four match in both top builds)
  • Skill order: Q > W > E

Where the aggregators diverge

  • Items 5-6: Jungler.GG → Serpent's Fang · Serylda's Grudge. WR Meta → Serylda's Grudge · Edge of Night. (Serpent's Fang becomes a situational swap on WR Meta vs shield-heavy enemies.)
  • Late-game flex: WR Meta enumerates an explicit situational pool; Jungler.GG publishes one canonical build.
