Optimizing your unit’s skill tree in All Star Tower Defense X transforms a decent team into an unstoppable force. Upon reaching level 18 and obtaining a five-star or Unbound character, activating nodes enhances destructive potential, accelerates attack cycles, and broadens area coverage dramatically.
This walkthrough details efficient orb acquisition strategies, managing duplicate heroes, and activating game-changing upgrades that redefine combat capabilities.
Skill Tree Mechanics in All Star Tower Defense X
Three primary branches structure each skill tree, activated through color-coded Skill Orbs matching unit elements. Missing optimal orbs? Convert general Pure Skill Orbs to specific types. Commence upgrades by selecting branch origins, confirming orb expenditures, and progressively unlocking statistical improvements and combat modifiers.
Key Skill Tree Components
| Feature | Description |
|---|---|
| Locked Units | Three slots requiring duplicate units for activation through dedicated nodes |
| Special Cells | Flexible slots housing passive abilities earned from branch completions |
| Fast Unlock | Accelerated path completion by bulk-using orbs, bypassing dupe requirements |
| Range | Expansion upgrades for maximizing area-of-effect coverage |
| Speed | Enhancements for attack frequency and ability cooldown reduction |
| Damage | Upgrade path focusing on raw offensive power amplification |
Duplicates and Ability Synergy
Three duplicate nodes per skill tree mandate sacrificing extra unit copies – four total copies complete maximum upgrades. Terminal nodes on each branch grant potent passive boosts like +10% Critical Chance, movable between four Special Cells for strategic loadout customization.
Orb Acquisition Tactics
Post-level 20 Challenges Mode offers rotating skill orb rewards every half-hour. Prioritize:
- Element-specific trials for colored orbs
- Limited-time events rewarding adaptable Pure Skill Orbs
Active codes may provide Skill Orb Bags containing random types. Regular challenge participation and strategic summoning remain vital for sustaining orb supplies.
