Last Z Research Costs Atlas — All Research Trees, Badge Totals, and Unlock Paths
This atlas is the fastest way to compare all major badge-heavy research trees in Last Z. Use it when you want to see total branch cost, unlock requirements, and the exact tree page for each branch without jumping through the whole site blindly.
Use this page to compare every major research branch by total badge cost, unlock path, and practical value. It is the main entry point for exact node trees and badge planning across the whole research cluster.
Quick Answer
Best way to use the research atlas: start with Hero Training to Cockpit, move into Military Strategies and Peace Shield for efficient mid-game value, and treat Unit Special Training as the biggest late-game badge sink rather than an early goal.
- Best early stop · Hero Training to Cockpit
- Best mid-game value · Military Strategies and Peace Shield
- Largest branch · Unit Special Training at 1,488,100 badges
- Late-game follow-up · Field Research and Army Building
Key note: not every expensive branch is a priority branch. Some trees are foundational, while others are late-game badge pressure that only makes sense once the earlier route is already secure.
Recommended Research Route
For most players, the cleanest badge route is to secure the efficient early and mid-game branches first, then decide whether your account should push deeper into late-game trees.
- Hero Training
- Military Strategies
- Peace Shield
- Siege to Seize
- Field Research
Later pressure branches: Alliance Recognition, Army Building, Fully Armed Alliance, and Unit Special Training are not “do this immediately” pages. They are the branches where badge planning starts becoming a major account commitment.

Step 1: Compare total cost before you commit
Use the totals here to see whether a branch is a quick checkpoint or a multi-month badge sink. This prevents expensive branches from looking deceptively close just because the first few nodes are cheap.
Step 2: Open the branch tree page
Every card leads to a full branch page with the exact node tree, grouped costs, and the real checkpoint that matters before you finish the whole branch.
Step 3: Compare branch order with your account goal
If your account still needs efficient mid-game value, open Hero Training, Military Strategies, and Peace Shield first. If your goal is true late-game badge planning, move into Siege to Seize, Field Research, Army Building, Fully Armed Alliance, and UST only when the earlier route is already secure.
