Switch System

The Switch System is Echoes of Aincrad's core companion-coordination mechanic. It is the specific term Bandai Namco uses for how the player and their NPC companion hand combat off to each other during fights.

Chaining Attacks

At its simplest, the Switch System lets the player chain attacks with their partner and change roles during a fight. One character opens a combo, the other closes it, and the pair can then rotate without the fight losing momentum.

Autonomous vs Held

The player has two modes for how the partner behaves. In autonomous mode the partner acts on its own, fighting freely alongside the player. In the held mode the player specifically holds the partner back, then triggers a coordinated attack that splits damage between the two of them for a larger combined strike. Deciding when to release the partner is one of the tactical inputs the system puts on the player.

Where it Meets the Timing System

The Switch System pairs with the game's defensive timing windows. Successful Parry Slash, Dodge Slash, and Reversal Slash all rely on the partner stepping in at the right moment, which means Switch positioning and timed parry reads drive each other in practice.

Free Mode and Switch Mode

During battle, players can alternate between two behavior modes for their AI partner. The choice changes how the partner engages enemies and how the player uses their own evades. Swapping modes is expected to happen constantly mid-fight rather than being set once at the start of an encounter, and ties directly into the broader combat system.

Free Mode

In Free Mode, the partner attacks nearby enemies on their own using basic attacks and their assigned sword skills. This is the mode to reach for when the character is surrounded or when the player wants the partner to spread pressure across multiple targets at once. It lets the partner fight largely unsupervised so the player can focus on positioning, combos, and special skills.

Switch Mode

In Switch Mode, the partner takes a defensive stance and is much less likely to engage enemies on their own. Instead, the partner waits. When the player performs an evade with their main character, the partner is called in to switch, jumping in to attack the target and attempting to pull aggro off the player. That breathing room is what lets the player reposition, reset spacing, or use a healing crystal without being pressured.

Switch Cooldown

The switch does not appear to trigger after every evade while Switch Mode is active, which suggests an internal cooldown on the ability. After a switch resolves, the HUD icon updates to show the player's character in a back-row position, implying a brief window where the player cannot call the partner back in again. Once the icon returns to its normal state, the next evade in Switch Mode can trigger another switch.

Expected Play Pattern

Because the two modes cover different situations, the intended play pattern is to alternate between them constantly rather than picking one and sticking with it. A rough rule of thumb based on the behavior shown in gameplay footage:

• Free Mode: use when the character is surrounded or the player wants the partner to apply area pressure on multiple enemies at once.

• Switch Mode: use when the player needs a defensive window to recover, heal, or reposition, and wants evades to pull the partner in to cover for them.

Both modes still respect the normal resource loop. The partner's sword skills draw from their own SP, and holding back in Switch Mode can help conserve the buildup required for coordinated attacks and support skills. Managing stamina on the player's side also matters, because evading is the trigger that calls the partner in, and running dry on stamina means losing the option to switch on demand.

Switching and Tag-Team Counterattacks

Switching is the same system that powers tag-team counterattacks for perfect dodges, parries, and blue-ring interrupts. When the player nails the defensive timing, the partner is the one who actually jumps in to counter, so Switch Mode's evade trigger and the perfect-timing reactions share the same underlying handoff logic. The detailed inputs for each counter window are covered on the Parry Slash, Dodge Slash, and Reversal Slash page, but the practical result is that the more comfortable the player is alternating modes and using evades deliberately, the more often those tag-team reactions come online in combat.

Two-Player Partner Combat

The publisher's headline framing for the Switch System is that Echoes of Aincrad is built around two-player partner combat: the protagonist and a single AI-controlled NPC companion form the unit that every other combat system pivots on. Although the game itself is single-player, the moment-to-moment fight is paced like a duo, with both characters contributing damage and pressure on the same target window.

That framing has two practical implications. The first is that successful combat usually means coordinating your inputs with whichever partner is currently held back, since the largest damage spikes come from the held-and-released sequence rather than from raw player damage on its own. The second is that partner choice carries the same weight as weapon choice: rotating Iori, Wyzeman, Zash, and Argo through a long encounter changes which timing reads matter and which special skills the team has on the menu.
