Last Z Unit Special Training Costs — T10 Path and Total Badge Cost
Unit Special Training is the real T10 badge wall in Last Z. This branch is not an ordinary mid-game branch — it is a long-term endgame commitment, and most accounts need exact totals before they decide to chase it seriously.
Use this page to see the total Unit Special Training badge cost, understand the late-branch structure, and judge how far your badge stash really goes before the final T10 unlock.
Quick Answer
Best Unit Special Training rule for most players: treat UST as a long-term endgame branch, not an early badge goal. The full path costs 1,488,100 badges and the final Unit Special Training node only appears after you have already burned through almost the entire branch.
- Full branch cost · 1,488,100 badges
- Final unlock · Unit Special Training at 1,488,100 cumulative badges
- Best use · Late-game T10 progression only
Key note: UST is one of the clearest badge-trap branches for players who start chasing it too early. Most accounts should only plan it after the rest of the account foundation is already strong.
Unit Special Training is the branch people mean when they talk about the true badge wall for T10. It is massively more expensive than the branches before it, and the final unlock only comes after a long sequence of already expensive nodes.
- Total cost: 1,488,100 badges
- Branch size: 22 nodes / 220 total levels
- Final unlock: Unit Special Training
- Unlock requirement: Lab Level 30

Unlock Requirements and Why This Branch Matters
UST is not a normal branch you just drift into. It is a late-game branch that exists for players who are deliberately planning T10 and understand the badge cost in front of them.
- Unlock requirement: Lab Level 30.
- This branch is the real T10 badge wall.
- The final Unit Special Training node is only a small part of the total cost — most of the branch cost comes before it.
If your account still lacks efficient mid-game value in Hero Training, Military Strategies, Peace Shield, or Field Research, those branches usually deserve badges first.
Key Unit Special Training Checkpoints
First major wall — 286,600 badges
Even before the later repeated 116,500-badge nodes begin, UST has already eaten more badges than many full branches on the site.
Mid-branch before the second wall — 515,200 badges
By the time Demolition Crew is finished, you are already deep into a commitment that most players cannot reverse efficiently.
Recharge Shield reached — 1,433,200 badges
The final Recharge Shield is itself enormous and arrives only after the branch has already consumed nearly all of the total UST cost.
Full branch — 1,488,100 badges
The final Unit Special Training node is only the last step of a branch that is already brutally expensive long before the finish line.
How to Think About UST
UST is less about "what should I research next" and more about "is my account finally ready to commit to the T10 badge wall." For most players, that answer comes much later than they expect.
Use the Research Guide and Field Research to compare whether your next badge push should really be UST or whether cheaper branches still give better growth.
