General Strategy Guide

Deck Building Principles
- Slim Deck: Aim for 20-25 high-quality cards, avoid bloat
- Survival First: Ensure adequate defense before pursuing synergies
- Build Around What You Get: Adapt strategy based on cards received, don’t force specific archetypes
- Active Removal: Remove Strikes and Defends promptly to improve deck consistency
Path Selection
| Node Type | Priority | Notes |
|---|---|---|
| Elite | High | Drop relics, avoiding elites is a trap |
| Shop | Medium | Remove cards, buy key relics |
| Rest Site | Medium | Prioritize upgrading over healing |
| Event | Low | Risk/reward is inconsistent |
Recommendation: Challenge at least 2 elites per act for relics.
Act Priorities
| Act | Characteristics | Strategy |
|---|---|---|
| Act 1 | Build foundation | Prioritize attacks and key Powers, keep deck under 15 cards |
| Act 2 | Complete synergies | Add defense, establish core combos |
| Act 3 | Optimize deck | Remove excess cards, aim for stability, target 20-25 cards |
Resource Management
- HP: Treat as spendable resource, don’t aim for full health clears
- Potions: Use early, don’t hoard for Boss only
- Gold: Prioritize key relics over marginally better cards
Upgrade Priority
Priority Order:
- Core damage cards (e.g., Demon Form)
- Draw/Energy cards (e.g., Adrenaline)
- Defense cards (e.g., Barricade)
Starting Choices
Neow’s starting options:
- Safe choices: Card reward, heal, or remove card
- Avoid: Random Boss relic (too risky)
Common Mistakes
- Avoid oversized decks (over 30 cards)
- Don’t pursue perfect synergies at the cost of survival
- Don’t hoard potions
- Avoid skipping elites
