Research Guide
All ~13 Lab trees: Development, Economy, Hero factions, Alliance Duel at Lab 15, Soldiers, Elite Troop, and the mistakes that waste weeks of timers.

System
The Lab runs one project at a time (a second queue is a huge upgrade). Research is a permanent account multiplier. There are about 13 trees.
Tree overview
| Tree | Gives |
|---|---|
| Development | Build/research/train/heal speed, infirmary, Training Grounds unlock |
| Economy | Production, gathering, extra Herb Garden slots |
| Hero: Warrior / Ranger / Warlock | ATK/DEF/HP for that faction only |
| Alliance Duel | Event reward tiers / multipliers (Lab 15+) |
| Soldiers | Troop load, ATK/DEF/HP |
| Squad 1–3 (+4) | Per-squad combat buffs |
| Elite Troop | T10 hard gate |
| Offensive / Defensive Tactics | Late combat (high Lab required) |
| Caravan Transport | Caravans — later |
Priority for most accounts
1. Development — always first
Inside Development, hit these immediately:
- Training Grounds unlock
- Construction Master (~−5% build time per node)
- Research Speed (~+10% — critical on 20–30 day timers)
Then healing, production, and infirmary nodes.
2. Economy — Herb Gardens first
Extra Herb Gardens exist only in this tree. After the slots, push gathering speed (it scales with marches better than raw production).
3. Hero tree = Squad 1 faction
Do not spread research across three factions. Composition bonuses:
| Same-faction heroes in Squad 1 | Effect (community) |
|---|---|
| 3 | ~5% attributes |
| 4 | ~15% |
| 5 | full dual-bonus |
4. Alliance Duel at Lab 15
Immediately: Tier 4–6 reward unlock → Arena Expert 20 → Tier 7–9 → finish Arena Expert. Missed chests never come back.
5. Later
Soldiers (Load Training first) → Squad 1 → Elite Troop (T10) → Squad 2/3 → Tactics → Caravan.
Dual queue
Queue 1: Alliance Duel critical nodes. Queue 2: Development / Soldiers. Do not open two late trees first.
Mistakes
- Treating quests as a research roadmap
- Spreading all three Hero trees
- Delaying Herb Gardens
- Ignoring Alliance Duel after Lab 15
- Rushing Tactics with weak Development/Economy
- Leaving the Lab queue idle
