Last Z Unit Special Training Costs — T10 Path and Total Badge Cost
Quick Answer
Best Unit Special Training rule for most players: treat UST as a long-term endgame branch, not an early badge goal. The 22-node path costs 1,500,300 badges; Recharge Shield is the penultimate node, and the final Unit Special Training node unlocks T10 troops.
- Full branch cost · 1,500,300 badges
- Final unlock · Unit Special Training at 1,500,300 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: 1,500,300 badges
- Branch size: 22 nodes / 246 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.

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.
