Updated 10/12/2026
| Building | Main value | Best use |
|---|---|---|
| Command Post | Season Troop DMG | Multiplies seasonal troop damage in both attack and defense |
| Icy Arsenal | Season Troop ATK | Increases troop ATK in both attack and defense |
| Icy Fort | Season Troop DEF | Increases troop DEF in both attack and defense |
| Building | Base F2P cap | Per-level value | Value at base cap |
|---|---|---|---|
| Command Post | 30 | +1% Season Troop DMG | +30% Season Troop DMG |
| Icy Arsenal | 50 | +3% Season Troop ATK | +150% Season Troop ATK |
| Icy Fort | 50 | +3% Season Troop DEF | +150% Season Troop DEF |
| Goal | Recommended checkpoint | Why it matters |
|---|---|---|
| Kill level 60 Frostbanes before switching into Combat | Bio Lab level 26 | Provides the maximum Frostbane access checkpoint while you remain outside Combat |
| Switch into Combat and keep killing level 60 Frostbanes | Bio Lab level 28 | Compensates for the resistance lost when switching away from the Support path |
| Begin heavier combat-building investment | After the Bio Lab checkpoint required by your current Mastery path | Prevents combat upgrades from breaking your Frostbane farming access |
| Situation | Best move | Why |
|---|---|---|
| Bio Lab is below level 26 and level 60 Frostbanes are the goal | Reach Bio Lab 26 first | Level 26 unlocks maximum Frostbane access before the Combat switch |
| Bio Lab is blocked by Ice Blooms | Save current production for a small shortfall; fund an upgrade only if it repays its cost in time | Spending scarce Ice Blooms on an upgrade can delay the Bio Lab level you need |
| Bio Lab is blocked by Frost Cores | Protect Frostbane and alliance target value | Spending Frost Cores elsewhere can delay the next resistance step |
| No urgent PvP window | Stay progression-first | Combat stats are less valuable if the alliance is not using them right now |
| Current choice | Best move | Decision rule |
|---|---|---|
| Starting combat buildings | Command Post | Season Troop DMG makes it the first overall combat priority |
| Next Command Post level is still affordable | Continue Command Post | Keep the primary path moving while its resource cost remains reasonable |
| Next Command Post level is disproportionately expensive | Upgrade Icy Arsenal and Icy Fort | Cheaper +3% Season Troop ATK and +3% Season Troop DEF levels can increase troop strength more efficiently |
| Combat building costs are close again | Return to Command Post first | Do not permanently abandon the main Season Troop DMG path |
