Upgrade Sweet Spot Optimizer
Find the optimal upgrade level for Astral DOT builds. Discovers the "Upgrade 2 Paradox" where lower upgrades can outperform higher ones.
Unit baselines use canonical Trello-backed unit stats (Likely, checked 2026-07-06). Trait effects use the canonical Trello-backed dataset, checked 2026-07-06. Upgrade levels remain calculator assumptions and should be verified in-game.
The "Upgrade 2 Paradox"
With Astral trait, higher upgrades are NOT always better. Here's why:
- • Higher upgrades increase damage but decrease attack speed
- • Astral DOT stacking benefits from faster attacks (more stacks)
- • The optimal point balances damage per attack vs attack frequency
- • For Ace with Astral, Upgrade 2 (~6,000 gold) is often optimal
⚙️ Configuration
❓ How to Use the Sweet Spot Optimizer
- Select Unit & Trait: Choose a DOT unit and set the trait to "Astral" to enable the paradox logic.
- Set E-Level: Adjust the E-Level to reflect your unit's stats (E6 gives 100% DOT coefficient).
- Input DOT Duration: Enter the duration of your DOT effect (defaults to 5s).
- Find the Sweet Spot: Look for the "Optimal for Max DPS" result. For Astral builds, lower upgrades (like Upgrade 2) often outperform higher ones due to attack speed scaling.

How It Works
Astral DOT Stacking Mode
With Astral trait selected, the calculator uses DOT stacking formula: faster attacks = more stacks = higher DPS. This often makes lower upgrades optimal.
Standard Mode (Non-Astral)
Without Astral, uses standard DPS formula where higher upgrades are always better.
Note: Actual upgrade values may vary slightly in-game. This calculator uses community-researched estimates. Always verify with in-game testing.
