How to Position Units in Legion TD

Buying the right units is only half of a Legion TD defense. Positioning decides which unit is hit first, whether enemies surround the formation, how long ranged damage keeps firing, and whether support effects reach the units that need them. A strong layout creates a deliberate contact point instead of letting the wave choose one for you.

Why the wall matters

An army standing in open ground can be approached from several angles. When the main contact point is placed near the lane wall, one side of the formation is protected by terrain. That usually reduces the useful surface available to the wave and makes enemy movement more predictable.

The goal is not to stack every unit into one tile. It is to form a compact column with durable units at the contact point and enough room behind them for damage dealers to acquire targets.

Build vertically instead of forming a wide front

A wide horizontal row invites the wave to touch several defenders at once. It can also cause backline units to step forward around one another. A vertical or gently staggered column along the wall encourages a smaller number of defenders to take initial contact while the rest of the formation contributes from behind.

Treat this as a baseline, not an unbreakable rule. Unit collision, range, movement, summoned units, and the wave itself can all justify extra spacing. Watch the first contact in a replay and adjust from evidence.

Use a puller to shape the approach

A puller is a unit placed ahead of the main formation so it acquires or attracts the wave first. Long range is useful because the puller can influence pathing without immediately becoming the entire frontline. Its job is to bring enemies toward the wall-side contact point where the formation is prepared to fight.

• Place the puller forward and near the intended wall-side path.
• Keep the main frontline behind it, close enough to take over contact.
• Confirm that the puller survives long enough to perform its pathing job.
• If it isolates itself or drags enemies past your damage, move it back or change the angle.

Give every role a depth

Frontline

Durable melee units belong nearest the planned contact point. Their purpose is not merely to survive; it is to buy uninterrupted attack time for the rest of the formation. Staggering them can keep the wave concentrated instead of opening a broad line.

Backline damage

Ranged and fragile damage units should begin behind the frontline but remain close enough to attack promptly. Too close and they may be surrounded when the frontline falls. Too far away and valuable seconds are lost to movement or target acquisition.

Aura and support

An aura’s best tile is the one that covers the units responsible for the current plan—not necessarily the geometric center of every unit you own. Fragile support units should normally sit behind the first contact, while still reaching the frontline or damage group they enhance.

Vulnerable and scaling units

Eggs, delayed-value units, and other pieces that must survive to become useful belong at the safest practical depth. Do not place them where a single frontline collapse immediately exposes them.

Diagnose the formation, not just the result

“I leaked” does not identify the positioning error. Slow the replay down and find the first moment where value was lost. The correct adjustment depends on what happened.

A practical setup sequence

1. Choose the wall-side area where you want the main fight.
2. Place the frontline as a compact, slightly staggered column.
3. Place damage units behind it with clear target access.
4. Position aura and support units around the units they must affect.
5. Put vulnerable scaling pieces at the protected rear.
6. Add a puller only when it improves the approach in actual tests.
7. Review first contact and change one variable at a time.
