Mythic Expedition: How to Unlock Secret Itachi Solo with 2 Mythic Units

To unlock Secret Itachi in Mythic Expedition without relying on Unbound upgrades, spend your stamina exclusively on limited-time event stages using a duo of two high-tier Mythic units. Running a reduced squad concentrates stage experience into your primary carries, allowing non-Unbound units to reach the damage and survivability thresholds required to clear event bosses.

Focus Resources on Event Stages

Secret Itachi requires exclusive event currency rather than standard campaign progression.

Direct Energy to the Event Map: Stop pushing standard campaign nodes during the event window. Reserve all daily energy strictly for event stages to accumulate the currency needed for unlock milestones.
Monitor Daily Shop Rotations: Check the event shop daily. Purchasing event summon tickets or unit fragments consistently prevents resource bottlenecks near the end of the event window.
Avoid Roster Splitting: Do not spend upgrade resources on temporary filler units. Reserve all character materials and high-stat artifacts for your primary two event carries.

Build a Two-Mythic Synergy

Clearing late event nodes without Unbound characters requires strict role division between your two Mythic choices.

Role	Preferred Unit Characteristics	Strategic Purpose
Frontline Tank / Sustainer	High survivability, self-healing, or crowd control	Draws enemy aggro and stalls wave pushes
Backline DPS	Area-of-Effect (AoE) or high single-target burst	Clears minion waves quickly and passes boss DPS checks

Running only two units split across these roles ensures both characters hit maximum level caps faster than a full six-unit squad, compensating for the lack of Unbound stat bonuses.

Execute Positioning for Event Bosses

Proper lane placement determines whether a two-unit composition survives high-difficulty stages:

Absorb Initial Aggro: Place your tanking Mythic directly in the lane with the heaviest initial enemy density to prevent mobs from advancing.
Protect the Damage Dealer: Position your burst DPS unit on the opposite side or behind the tank to keep them free from collateral damage.
Adjust for Rear Spawns: On stages with flankers or backline spawns, shift your damage dealer closer to the tank or equip a shield-providing artifact to prevent direct wipes.
