Spirit Conclave: The 11th-Edition Aeldari Wraith Detachment

Two parts. Spirit Guides (Aura): while a Wraithblades, Wraithguard or Wraithlord unit is within 12" of your Asuryani Psykers it gains the Battle Focus ability — which Wraith constructs normally lack — and Wraithblades and Wraithguard become Battleline, so they score. And Vengeful Dead: when one of your Psykers is destroyed, the killer gets a token, and your Wraith attacks gain +1 to Hit and +1 to Wound against tokened units. So a dead Spiritseer isn't a loss — it turns your whole ghost army up a gear against that enemy.

• Wraithbone Armour (defensive) — -1 Damage to attacks against a Wraith unit. Superb tech to weather a big hit.
• Seer's Eye (Shooting/Fight) — a Wraith unit ignores modifiers to AP and Damage, so -1-Damage tricks can't blunt your wraithcannons.
• Blades From Beyond (Fight) — Devastating Wounds on a Wraithblades, Wraithlord or Wraithknight.
• Crushing Strides (Charge) — mortal wounds after a Wraith charge (scaling up to 6D6 for a Wraithknight).
• Soul Bridge — extend the Spirit Guides aura to a flanking Wraith unit.
• Spirit Token — make a Wraith-held objective sticky.

All go on a Spiritseer:

• Light of Clarity — big Objective Control boost to a nearby Wraith (+3 for Monster wraiths), letting a Wraithlord bully objectives.
• Rune of Mists — Benefit of Cover against long-range shooting, for durability.
• Stave of Kurnous — Precision on Critical Wounds, to snipe enemy characters.
• Higher Duty (reworded for 11th ed) — a reactive 6" move when an enemy ends a move within 8".

• Wraithguard (wraithcannon or D-scythe) — the durable Battleline gun core; ignore Damage reduction via Seer's Eye and score as troops.
• Wraithblades — the Battleline melee anchor; the payoff for Blades From Beyond and Crushing Strides, plus Wraithbone Armour for survivability.
• Spiritseer — the linchpin: the Spirit Guides aura, and the only carrier for all four enhancements. Bring more than one.
• Wraithlord / Wraithknight — Monster and Titanic hammers that love Light of Clarity and Crushing Strides.
• Farseer — an extra psyker to feed auras and, grimly, to place Vengeful Dead tokens.

Choose it for a Wraith 'brick' army — a slow, extremely tough core of Wraithguard, Wraithblades and Wraithlords led by Spiritseers — rather than a fast Aspect or Guardian list. It's the pick for a durable midfield that trades well and holds objectives, and it's strong into high-Damage shooting (Wraithbone Armour and Rune of Mists blunt it). At 2 DP it leaves 1 DP for a support.

Sample gameplan: anchor the board with Wraithguard and Wraithblades led by Spiritseers so every Wraith unit sits in the 12" aura and gets Battle Focus; stretch it with Soul Bridge. Advance the brick onto midfield objectives, tanking fire with Wraithbone Armour and Rune of Mists. On the turn you commit to melee, charge with Wraithblades and fire Crushing Strides for mortal wounds, then swing with Blades From Beyond. Don't over-protect Spiritseers — trading one to place a Vengeful Dead token turns the rest of the army up a gear.
