Spellweaver Emblem

The Spellweaver Emblem grants Set 18's magic-damage class — 2/4/6 thresholds across the joint-widest class roster: seven champions. Karma and Veigar at one cost, LeBlanc at two, Cassiopeia and Fiddlesticks at three, Ahri at four and Alune at five. The bonus compounds during a fight rather than sitting flat: your team gains Ability Power, Spellweavers gain more, and every time a Spellweaver casts an Ability the team picks up additional Ability Power. That third clause is the one that shapes emblem decisions, because it converts cast frequency into a scaling team buff — more Spellweaver bodies casting means the number climbs faster, independent of the tier you are sitting at.

Spellweaver is the AP spine of the set, and its seven-member roster means natural counts run high — the emblem usually finishes a 4 or pushes a committed board to 6. Crafted from Golden Frying Pan + Needlessly Large Rod, it competes with your AP carry's core component and with the Blossom Emblem, which needs the same Rod; the discipline is the same either way — itemize the carry first. With two one-cost members, early Spellweaver counts are cheap, so the emblem's leverage peaks mid-game when 4 comes into range. There is a holder wrinkle specific to the stacking clause. An emblem holder counts as a Spellweaver for the trait, so putting it on a unit that casts frequently feeds the per-cast bonus as well as the tier count, while putting it on a slow-cycling body buys the tier and nothing more. Seven members also means the 6 is reachable without any emblem at all — which reframes the craft as a way to reach that tier a body short and spend the freed slot on frontline your all-caster board would otherwise lack.

Spellweaver bridges Blossom twice (Karma, Ahri), Coven (Cassiopeia), Elderwood (LeBlanc), Blackthorn/Sprykin (Veigar), Defender/Flora Fatalis (Fiddlesticks) and Lunar/Attuned (Alune) — nearly every origin with an AP identity routes through this class. Fiddlesticks is the standout, since he is one of only two Flora Fatalis champions in the set and simultaneously a Defender, making a single three-cost slot count toward three separate traits. Karma and Veigar do the cheap version of the same trick at one gold each, which is why a Spellweaver 2 costs almost nothing to hold while you decide whether the vertical is worth the Rod.

• 1Even thresholds on a wide roster: the emblem's most common conversion is 3→4.
• 2The Rod cost is your AP carry's core component — itemize the carry first, always, and note the Blossom Emblem wants the same piece.
• 3The trait grants extra Ability Power on every Spellweaver cast, so the emblem does more on a frequent caster than on a body added purely for the count.
• 4Seven members means Spellweaver 6 is possible without an emblem — the emblem's payoff there is the slot you can give back to frontline.
