Best Echo Cost Combination

Level Up the Data Bank to Increase Cost Limit

Keep an eye on your Cost Limit. This will dictate what type of Echoes you can equip.

You'll start the game with a Cost Limit of 8. This will then quickly upgrade to 10 when you reach Data Bank level 2.

At Data Bank level 9, your Cost Limit will reach its maximum of 12. However, to get to level 9, you need to reach SOL3 Phase 3 since the Data Bank will stop leveling up past 7 until you reach this phase.

Use the 43311 Combination for the Mid to Late Game

The Echoes you capture have different types of costs: the 1-, 3-, and 4-Cost Echoes. This will determine which Echoes you can equip in your inventory.

• One 4-Cost Echo
• Two 3-Cost Echoes
• Two 1-Cost Echoes

In this way, you can optimize your character to have the best stats for each type of Echoes, allowing for variations of strong builds.

Build Around Sonata Effects

Before equipping Echoes, be sure to plan around their specific Sonata Effects.

Depending on your playstyle or the character you're building, you can equip two pairs of Echoes with the same Sonata Effects to get two different types of 2 set bonuses or you can equip five Echoes of the same Sonata Effect to get its full 5 set bonus.

Remember that equipping the same Echo will not count towards the set bonus. For example, equipping two Molten Rift Fusion Dreadmanes will only count as one Molten Rift set piece.
