Resource Allocation Warning

New players start with limited resources like 300k resources, 2 Black Books, and β chips. Do not waste them blindly on heavy construction or random units. Prioritize wisely to avoid setbacks.

Stat Allocation & Unit Progression

Proper stat allocation is vital for maximizing your team's effectiveness. Following a clear guideline for each unit type will prevent common mistakes and ensure your Bioroids are battle-ready.

Stat Allocation Guide

Unit TypePrimary Stat FocusSecondary Stat Focus (if applicable)Thresholds (DPS)
Damage Dealers (DPS)100% Critical Rate (with passives/chips)All remaining points into ATKAccuracy ≥300%, Armor Penetration ≥90%
Evasion TanksMax EvasionN/AN/A
Defense TanksBalanced DEF and HPN/AN/A
Farming Miho and Next DPS

Farm T-14 Miho at 3-8 for copies to link her up. Later, progress to 5-8 to farm X05, who can serve as your next main DPS unit, providing a smooth transition for your Last Origin R best team composition.

Key Resource Management

1

Resources

Save resources for offline recovery and equipment enhancement. Avoid dumping all resources into heavy construction early on, as it's inefficient and risky.

2

Black Books

These instantly max a unit's level and skills. Save them for late-game meta units like No.85 Invincible Dragon. If absolutely necessary for early game, use one on T-14 Miho or No.7 Scissors Lise.

3

Equipment

Upgrade your free β chips (CRIT, ATK, EVA, SPD) to +10 first. Equip CRIT/ATK chips on Miho, and later transfer them to Scissors when you reach 5-8EX. Aim for +10 SS gear for key damage dealers in mid-game.

4

Cores

Use blue common cores freely for early links. Gold rare cores are extremely limited—save them for top-tier endgame units like No.2 Lavata and No.85 Invincible Dragon.

Tuna Cans & Common Beginner Mistakes

Tuna Cans are the premium currency in Last Origin R, primarily used for account storage and team slot expansion. Wise spending of this limited resource is critical for long-term account growth.

Tuna Can Prioritization

Smart Tuna Can Usage

By prioritizing deployment slots, you maximize your passive resource generation, which fuels your team's growth. This is a core strategy for building the Last Origin R best team efficiently.

Common Beginner Mistakes Checklist

Avoid These Pitfalls:

  • Mindless spending of Tuna Cans on gacha skins or unnecessary slots.
  • Over-reliance on SS units and neglecting free, easy-to-build B/A-tier teams like Mongoose.
  • Ignoring stat thresholds (100% Crit, 300% Accuracy, 90% Armor Penetration).
  • Wasting Black Books on random units instead of saving for meta units.
  • Dumping all resources into heavy construction early on.
  • Rushing hard endgame stages before mastering auto-farm and core team setup.
