Ageforge Keep Towers and Ultimates: How to Defend Your Base
Every Ageforge keep tower and ultimate explained: the one keep tower that upgrades itself each age, what it can and can't stop, and how to time Stampede, Arcane Storm, Artillery Barrage and Orbital Strike.

Key takeaways
- Every keep has exactly one tower. It starts as a Guard Tower and upgrades itself for free each time you advance an age.
- Towers can't be bought or upgraded with gold. They never take damage and always shoot the closest enemy in range.
- A tower picks off stragglers, but it can't hold a real push on its own. Your army defends your keep.
- Every tower out-ranges every unit (the longest unit range is 280), so no unit can shell your keep from safety.
- Every age has one ultimate. It is free, needs no aiming, hits the enemy army all at once and has a 42–60 second cooldown.
- Ultimates are softeners: a single cast never kills a full-HP unit of the same age, but it tips a close fight your way.
Keep towers
Your keep's tower shoots the closest enemy unit in range. It can't be attacked and never moves. There is only ever one, and when you advance an age it's rebuilt as that age's tower: stronger, longer-ranged and, from the Medieval Age on, hitting everything around its target.
| Age | Tower | Damage | Shots / sec | Range | Splash |
|---|---|---|---|---|---|
| Stone Age | Guard Tower | 14 | 0.8 | 280 | — |
| Medieval Age | Bulwark | 28 | 0.8 | 285 | 20 |
| Gunpowder Age | Citadel Battery | 50 | 0.8 | 290 | 30 |
| Future Age | Pulse Turret | 75 | 0.85 | 300 | 40 |
What a tower can and can't do
The tower is a deterrent, not a wall. It kills a lone unit that wanders up to your gate, and it punishes fast units that race ahead of their own army, because they are the closest enemy to your keep. It can't stop a full push by itself: if the enemy wins the fight on the lane and walks up with a real army, your keep falls. Hold the lane with units, and let the tower clean up what gets through.
Don't turtle behind it. Waiting at your keep for the enemy to attack into your tower gives away the shrine in the middle of the lane and the XP it pays, and if you leave the lane empty your keep starts to crumble on its own. See the shrine and the idle keep.
Ultimates
Each age has one ultimate, a lane-wide special with no gold cost and no aiming. After a short warning that both players can see, it deals true damage (armor doesn't reduce it) to the enemy army. Stampede, Arcane Storm and Orbital Strike hit every enemy unit on the lane; Artillery Barrage drops shells on the army instead, so packed formations take the most. The ultimate available to you changes when you advance, and its cooldown carries over.
| Age | Ultimate | Cooldown | Effect |
|---|---|---|---|
| Stone Age | Stampede | 60s | 40 true damage to every enemy, knockback, 45% slow for 2.5s |
| Medieval Age | Arcane Storm | 52s | 55 true damage to every enemy, 50% slow for 3s, burn 10/s for 3s |
| Gunpowder Age | Artillery Barrage | 45s | 6 shells of 75 damage (max 2 per unit) |
| Future Age | Orbital Strike | 42s | 190 true damage to every enemy, disables passives for 4s |
Stampede. A herd thunders down the lane: every enemy takes 40, is knocked back and slowed.
Arcane Storm. Arcane lightning strikes every enemy for 55, then burns and heavily slows them for 3s.
Artillery Barrage. Six shells bombard the enemy army, 75 each — packed formations take the most.
Orbital Strike. A beam from orbit hits every enemy for 190; its EMP shuts off their passives for 4s.
How to time your ultimate
- Wait for a crowd. Ultimates hit many enemies at once, so they're worth more when more enemies are on the lane.
- Cast mid-fight, not before it. An ultimate won't kill full-HP units on its own. Cast it when both armies are trading hits and the wounded units will die.
- Use it to turn a fight you're losing. When a big push reaches your keep, a cast together with your tower can wipe the whole wave and hand you its XP. A cast that wins the fight at the shrine also wins you the XP the shrine pays.
- It's ready from the first second. Your Stampede starts off cooldown. Spending it early is fine if it wins a fight, because it's back in 60 seconds.
