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.
Gaining XP Through Upgrades
The vast majority of your account experience will come from the simple act of upgrading your cards.
Conversely, upgrading a card to the absolute maximum level costs massive amounts of gold for a relatively small XP return.
- Farm masteries in casual modes.
- A high-level tower means nothing if your spells are weak.
- Participate in gold-rush events to fund these upgrades.
XP Through Generosity
Many players are stingy, refusing to donate cards because they want to hoard everything for themselves.
You are essentially converting cards you will never use into base hitpoints and currency.
| Experience Source | Value |
|---|---|
| Starter Leveling | Incredibly high efficiency; the absolute best way to gain quick XP if you have a slight gold surplus |
| Upgrading High-Level Cards (Lv 12-14) | Extremely low efficiency; costs 100,000 gold for a tiny XP bump, but mandatory for competitive viability |
The Impact of King Levels
If your king tower was one level higher, it would possess several hundred more hitpoints, turning that loss into a win.
Furthermore, higher level towers deal more damage per shot, altering crucial interactions against enemy swarms.
