Understanding Defensive Units and Enemy Waves

Selecting the right units is crucial for surviving the onslaught. Defensive units are categorized by their roles, damage types, and costs. Balancing single-target damage dealers with area-of-effect (AoE) splash units ensures that both high-health bosses and dense enemy swarms are handled efficiently.

Defensive Unit Archetypes

Different units excel at different tasks. For instance, melee guards are excellent for stalling enemies at choke points, while archmages deal devastating magic damage to grouped targets.

Step-by-Step Guide to the Perfect Castle Layout

Creating an optimized layout is the key to surviving late-game waves. Follow these steps to build a robust defense system that can withstand high-damage enemies.

1

Initial Setup

Place basic Castle Guards at the primary choke points near the enemy spawn paths. This slows down the initial scout waves and allows you to build up a gold reserve.

2

Ranged Coverage

Position Shadow Archers on the elevated walls near the choke points. The high ground provides a range bonus, allowing them to target enemies before they reach your guards.

3

Splash Damage Integration

As gold reserves grow, place Archmages at intersections where enemies tend to cluster. Their splash damage will clear out grouped enemies quickly.

4

Boss Activation

When the final boss waves approach, activate your boss character's ultimate abilities to clear any leaks that bypass your static defenses.

High Ground Advantage

Ranged units placed on elevated walls gain a 15% range boost and are safe from melee attacks.
