How to Play Sylvaneth in Warhammer Age of Sigmar (4th Edition)

Sylvaneth are a terrain-first army. The signature trait is The Creeping Overgrowth (sometimes read as 'creeping undergrowth'): you seed overgrown tokens from your forests, and the more tokens are on the board, the further your overgrowth rules reach. Early on it is a short bubble around your woods; stacked up, it can blanket the whole table. Almost everything else keys off being in that overgrowth.

The supporting traits layer onto that footprint:

• Reclaimed by Nature lets you keep growing your forest, setting up additional Awakened Wyldwoods so you rarely run out of woodland to work from.
• Endless Growth heals your units in the overgrowth or brings back slain models at the end of the turn, turning attrition in your favour.
• The Land Awakens resurrects a destroyed Dryad or Revenant-type unit at reduced strength inside your overgrowth, well away from the enemy.
• Fury of the Forest hands a unit standing in the overgrowth a strike-first punch in the right situation.
• Creeping Dread is the control lever: enemy units that stray out of the overgrowth (or away from their own heroes) pay a command-point tax to act, so they either huddle up or bleed resources.

The takeaway: your job is to grow the forest, fight inside it, and make the opponent play on your terms. I am describing these generally on purpose. Heal amounts, token thresholds, and exact ranges get tuned by errata, so read the live rules for the numbers.

Battle formations are 4th edition's replacement for the old subfactions, and Sylvaneth's core book gives you a handful, each bending the army toward a different plan. Pick one before the game and lean into it during list-building.

• Outcasts — the control build. It sharpens Creeping Dread so enemies have to hug their heroes tightly to dodge the command-point tax, and it hampers the enemy's grip on objectives. Great against horde or model-heavy armies where you are outnumbered.
• Followers of Kurnoth — the assassination build. It buffs a unit's accuracy when it is near the enemy general or Warmaster, so you can reliably delete the enemy's key character.
• Lords of the Clan — the monster-mash build. It makes your Endless Growth healing on Monsters reliable (a flat amount rather than a random roll), keeping Treelords, Durthu, and friends alive turn after turn.
• Glade Defenders — the resurrection/attrition build. It rewards you for losing units, handing survivors extra attacks based on what died last turn, so it pairs naturally with the army's recursion.

There is no single 'best' pick; it depends on your collection and your local meta. See the 'warnings' note about additional Wargrove-style formations from supplements — those exist, but confirm they are legal in your current rules pack before relying on them.

• Alarielle the Everqueen — flagship monster, healer, and buff engine; a huge points sink that anchors a Lords-of-the-Clan style list.
• Spirit of Durthu — hard-hitting monster hero, your premier duelist and objective-breaker.
• Drycha Hamadreth — monster caster/damage dealer, strong into infantry blocks.
• Treelord Ancient — support monster and caster, good at holding a flank inside the overgrowth.
• Kurnoth Hunters — the elite workhorse; swords for melee, scythes for volume, bows for ranged threat. Your main damage infantry.
• Dryads — cheap, resilient objective-holders and prime targets for resurrection traits.
• Tree-Revenants / Spite-Revenants — mobile screening and board-control infantry that recycle well.
• Revenant Seekers / Spiterider Lancers — fast cavalry for grabbing objectives and threatening backfield units.
• Gossamid Archers — mobile ranged skirmishers for chipping and repositioning.
• Branchwych / Branchwraith / Arch-Revenant — small support heroes for casting, buffs, and forest utility.
• Awakened Wyldwood — your faction terrain and the literal engine of the army; almost every rule flows from it.

Play Sylvaneth as a patient control army, not an alpha-strike list. The opening turns are about setup: plant and grow your Wyldwoods, spread overgrowth tokens so your rules reach further each turn, and use fast, expendable units (Revenants, cavalry, Gossamid Archers) to screen and grab early objectives.

As the overgrowth expands, the board tilts your way. Fight inside your own terrain so you benefit from healing, strike-first tricks, and Creeping Dread's command tax, while the enemy pays extra to operate or gets punished for stepping into your woods. Commit your hitters — Kurnoth Hunters and your chosen monsters — into fights you can win, knowing Endless Growth and your resurrection traits let you trade bodies and get them back.

Mid-to-late game you want to be the army with more models still standing and more of the board under overgrowth. Let the forest do the grinding: heal what lives, raise what died, and close out on objectives while the opponent runs low on command points and patience. Cast from the Lore of the Deepwood (mobility and buffs like charge-after-run and to-wound boosts) and pray from the Lore of the Spirit-Song (defensive debuffs, rend, and mortal-damage punishment) to tip individual combats.

Mistakes to avoid:

• Fighting outside your forest. Your traits reward being in the overgrowth. Charging naked into the open throws away your entire toolkit.
• Neglecting the terrain phase. If you do not invest in growing Wyldwoods and spreading tokens early, your rules never reach their full range and the army feels flat.
• Over-committing monsters too early. Alarielle and friends are expensive; feed them into a scrum before the overgrowth supports them and you can lose your centrepiece for nothing.
• Forgetting the recursion. Players routinely forget end-of-turn heals and resurrection windows. That is free value you are leaving on the table.

When they struggle: Sylvaneth are an elite, model-light army, so they can get swamped by wide horde lists that ignore the command-point tax and simply out-body you on objectives. Fast alpha-strike armies can also punish you before the overgrowth matures. Heavy anti-terrain or board-denial tools blunt your engine, and if your key monsters die before Endless Growth is online you lose the attrition war you are built to win.
