Rune Tree Progression & Hero Slots Guide
A full priority route for hero slots, early account economy, chest upgrades, offline rewards, and when to buy combat nodes.
Goal
Use this guide when deciding where gold should go in the Rune Tree. The early goal is not to buy every small combat node. The early goal is to unlock party size and account economy.
Priority Summary
| Priority | Upgrade type | Why it matters |
|---|---|---|
| 1 | Hero slots | More heroes are the strongest early multiplier. |
| 2 | EXP upgrades | Faster levels unlock more skill points and higher gear bands. |
| 3 | Gold upgrades | More gold accelerates the next rune purchases. |
| 4 | Chest drop chance | More items means more gear, materials, and alchemy fuel. |
| 5 | Automation and offline rewards | Smoother long sessions and better passive progress. |
| 6 | Combat nodes | Buy when survival or damage becomes the actual blocker. |
Unlock The Rune Tree
The Rune Tree unlocks once any hero reaches level 3. From that point on, rune upgrades act as permanent account progress and help every team.
Your early spending should point toward hero slots first. Party size improves damage, survival, clear consistency, and shared hero leveling.
Hero Slot Priority
Second Hero Slot
The second slot should be your first immediate target. It lets Priest support Ranger or lets a frontline start absorbing pressure.
Common early path:
Third Hero Slot
The third slot is a bigger milestone and should be planned around. Once you have Knight + Priest + Ranger together, the account becomes much easier to farm.
Do not delay the third slot by overbuying small low-impact nodes. A complete team normally gives more value than scattered minor bonuses.
Economy Cycle
After the key slots are online, rotate economy upgrades instead of tunneling one stat forever.
Upgrade EXP until expensive -> move to Gold -> move to Chest Chance -> return to EXP and Gold after farming improvesThis works because each upgrade improves the value of the next:
Useful Early Rune Categories
EXP Gain
Take EXP when hero levels are your bottleneck. More levels mean more skill points and faster access to gear breakpoints.
Gold Per Kill
Gold upgrades matter whenever your next rune or Cube goal is being delayed by currency.
Chest Drop Chance
Chest chance becomes stronger when your farm stage is stable and you can leave the game running. More chests create more equipment, alchemy fuel, crafting materials, and market chances.
Auto Chest Opening
Automation is useful, but do not let it conflict with chest strategies where you intentionally keep Common Chests capped for boss chest farming.
Offline EXP And Offline Gold
Offline rewards are good support upgrades. They do not replace online chest farming, but they keep the account moving when the game is closed.
Inventory And Stash
Storage upgrades are worth buying when farming sessions are being interrupted by full inventory. More storage can directly improve farming uptime.
When To Buy Combat Nodes
Combat nodes are not bad; they are just not always the best early investment.
Buy combat nodes when the problem is specific:
| Problem | Rune direction |
|---|---|
| Knight dies instantly | Defensive stats, HP, resistance, block, damage reduction. |
| Fights take too long | Damage nodes for your carry. |
| Team slowly loses HP | Healing, cooldown, sustain support. |
| Stage has elemental pressure | Relevant resistance or all-resistance support. |
If your team already farms safely, economy often gives better long-term value than another small combat increase.
