In most arena battlers, your account level (often represented as a King Tower or Base Headquarters) dictates the health and damage of your main defensive structures.

This guide will detail the most effective methods for leveling up your towers and securing that crucial hitpoint advantage.

If your sole goal is to level up your king tower quickly, upgrading all of your low-level cards evenly is the most cost-effective method.

The second most consistent way to generate base experience is by actively donating cards to your clanmates.

This is why joining an active clan of fifty people who constantly request cards is absolutely mandatory for free-to-play users.
