Grand Warden Fireball Guide 2026: The Levels That Matter

Everything else about it scales smoothly. Damage creeps up a little almost every level. The radius doesn't, and the radius decides how many buildings one throw can reach.

All numbers here are as of October 2026.

When you trigger the Warden's ability, he throws a giant fireball. It lands on the closest defense and explodes in a circle.

I pulled the Fireball page from the community wiki to get the details right. Three points matter.

First, it targets the closest defense, no matter how far away that defense is. Second, if no defense is available, it hits the closest target of any kind. Third, its splash damages ground and air units in the same blast.

It also gives the Warden a passive boost to his damage per second, even before you use the ability.

The wiki notes one more thing. At levels 24 to 27, the Fireball has the largest splash radius of any damage source in the game.

Here's the radius at every level:

That table is the whole strategy in miniature.

Going from level 8 to level 9 adds a tile of radius. Going from level 23 to 24 adds another. Every level between those two adds only damage.

Why does a tile matter so much? A circle's area grows with the square of its radius. A 6 tile blast covers about 44 percent more ground than a 5 tile blast. That's often one more defense caught in the same throw.

So don't stop at level 8 or level 23. Those are the worst places to leave it.

Here's what each throw does at the levels most players reach:

The damage climbs steadily, but the steps shrink. From level 1 to 15, a throw gains 1,600 damage. From level 15 to 27, it gains only 1,000.

That's normal for equipment. Early levels are cheap and big. Late levels are expensive and small, unless they bring a new radius.

The Blacksmith caps every epic piece. Its level depends on your Town Hall.

I checked the wiki's Blacksmith table to match them up:

Two things stand out. Every Town Hall from 8 up can reach the level 9 radius jump. And Town Hall 15 is the first that can reach the 6 tile blast.

So at Town Hall 15 or above, level 24 is the target. Below that, push it to your cap and stop.

I counted the ore for every level in the wiki's upgrade table. Here are the totals from level 1:

Level 9 is cheap. It costs just 10 Starry Ore, and it gives you the first radius jump.

The jump from 21 to 24 costs 9,600 Shiny, 600 Glowy and 120 Starry. That's the price of the 6 tile radius.

The last three levels, 24 to 27, cost 10,500 Shiny, 600 Glowy and 150 Starry for 200 extra damage. That's the weakest deal on the whole table. If you're short on ore, our guide to getting more ore covers every source.

The 6 tile radius didn't always wait until level 24.

I checked Supercell's January 2025 equipment balance post. It says, in one line, that they moved the Fireball's last radius upgrade to a higher equipment level.

The wiki's history fills in the detail. Since February 10, 2025, levels 18 to 23 use a 5 tile radius instead of 6.

That's why older guides and videos say the big radius arrives at 18. It doesn't anymore.

If you leveled it to 18 or 21 before that change, you lost the 6 tile blast. The only way back is level 24.

This is where most Fireballs get wasted.

The Warden is a ranged hero, so it's easy to misjudge which defense is closest. Fire too early and the ball lands on a lone outer cannon instead of the core.

There's a clean fix. Invisibility Spells hide defenses from targeting, so you can cover the outer ones and leave only the cluster you want to hit. The wiki lists this as a common Fireball setup. Our Invisibility Spell guide covers the placements.

Without spells, wait. Let the Warden walk until the cluster you want is the nearest defense, then fire.

One odd case is worth knowing. If every target is hidden, the ball flies straight up and explodes where the Warden stands. It still does splash damage there.

The Warden carries two pieces of equipment. The Fireball's partner matters.

The wiki names the Rage Gem as a strong pairing. Rage Gem raises the Warden's damage per second, and the Fireball adds its own passive damage boost on top. Together they make a Warden walk clear buildings faster.

Rage Gem also helps the troops near him. That's why it suits armies that follow the Warden, like Healer supported walks.

If your army needs protection more than damage, the Eternal Tome or Life Gem may serve you better. The Grand Warden equipment guide compares every piece he can carry.

The Fireball is a cluster killer. It shines when three or four defenses sit close together.

That makes it a good opener for a core push. One throw softens the middle of the base before your main army arrives.

It also hits air and ground together. Air Sweepers, Air Defenses and Scattershots in one tight group can all take damage from the same blast.

At Town Hall 16, it's the centerpiece of one army we've covered. The TH16 attack strategy guide shows it alongside Yetis and Root Riders.

Before you attack, look at the base. If its defenses are spread thin, the Fireball loses most of its value. If they're stacked, it's the best throw you'll make all game.

Maybe. It depends on how many gems you're sitting on.

The Fireball first appeared in the Super Dragon Spotlight event in March 2024. Since May 14, 2024, it can show up in the Trader for 1,500 gems, according to the wiki.

That's a lot of gems. But epic equipment is hard to get outside events, and you can't level a piece you don't own.

Buy it if you already run Warden walks and have gems with no better use. Skip it if you're still short on builders, because a Builder's Hut speeds up every upgrade you make.

And check the event calendar first. Epic equipment often shows up in medal events, like this month's Portal Pendant for the Minion Prince.

Here's the order that gets the most from your ore.

Step one. Push it to level 9 as soon as you can. It's cheap, and it's the first radius jump.

Step two. Level it toward your Town Hall cap, but only when it's the piece you bring into most attacks.

Step three. At Town Hall 15 or above, save for level 24. Don't stall at 21 or 23. You'd be paying for the levels without the payoff.

Step four. Treat 25 to 27 as optional. Spend that ore on a second piece first.
