Crystal Tech Strategy Guide
How to approach the crystal tech tree efficiently — for all spending levels.
General Strategy — All Players
- Invest into Crystal Cost Reduction first (Research Center + Cutting Corners I & II = 25% off)
- Then push straight to Special Concoction II — 25% healing cost reduction on T5 troops
- Focus one troop type to get there fast. Once unlocked, all other troop type techs open up and you can pick and choose
Order: Mines lvl 25 → Research Center lvl 25 → Cutting Corners I (max) → Cutting Corners II (max) → Special Concoction II
Pop-up buyers and higher spenders should max the economy tree on Day 1.
F2P / Small Spender (~$20)
Same as General Strategy, with one extra step — push some combat tech before Pass 4, then max economy after the fight.
- Mines lvl 25 → Research Center lvl 25 (or 18 if short on crystals)
- Cutting Corners I & II → some combat tech (before Pass 4)
- After Pass 4 fight: Cultural Exchange 15 → Barbarian Bounties 15 → Karaku Reports 15 → Special Concoction I
- Push to Special Concoction II. Skip Leadership I & II if F2P — go straight for other troop type stats instead
With only $20 + correct bastions you can enter King's Land with ~3 troop types nearly maxed and Special Concoction II done.
Why Special Concoction II?
