The Ring
You are a Warden of the ring.
The battlefield is a mossy stone plateau suspended over a bottomless abyss. Creeps pour from a blight-storm at one horizon and march the worn path toward the glowing Leak Well at the far corner. If they reach the Well, the sanctuary bleeds lives.
“The sanctuary wakes, Warden. Hold the line.”
Classic tower defense with deep attack-versus-armor counters, upgrade trees and economy mastery — the standalone successor to the Green TD lineage, rebuilt as a premium browser product.
Counters
Read the ring — or lose it.
✓ Correct counter
150%
Every wave telegraphs its armor: type, air, immune, invisible, boss. Colour never carries meaning alone — icon and label always travel with it.
✕ Wrong answer
30%
Waves three to six punish lazy builds on purpose. Skill expression starts in the first minute, not the fortieth wave.

Eleven families
Doctrines, not loadouts.
Towers unlock abilities at levels, and adjacent families create resonance — Siege with Frost, Aura with everything. The Annihilator demands maxed Siege, Air and Poison. It is glory, not a participation trophy.

Air
Air-only heavy magic bolts.
Multishot
Volleys up to three targets at once.
Frost
Splash chill; high levels sheet the ground in ice.
Chaos
Void blasts that cannot be evaded. Divine counter.
Destruction
Industrial rift-hammer: splash ground and air, never misses.
AntiAir
Hybrid ballista; doubles versus flying.
Detection
Does not attack. Reveals invisibles.
Aura
Does not attack. Empowers towers in range.
Annihilator
The Ultimate. Universal splash annihilation. Fusion-gated.
Bosses
Eight named things want the Well.
The Moss Colossus
The masonry remembers.
The Bramble Matriarch
Every thorn is hers.
The Gravewyrm
It digested the graveyard.
The Blight Alpha
The pack follows. It leads.
The Gilded Revenant
An oath outlived its knight.
The Emerald Lich
Sovereign of the second death.
The Abyss Behemoth
The plateau shakes first.
The Pantheon Betrayer
Half god. Half grudge.
Co-op

Shared lives. Per-player wallets. A lobby, a difficulty vote, and one ring between you and the abyss.
“The ring holds when the wardens hold together.”
Ranked

Ascension is scored on the server and validated by deterministic replay. Global boards split by difficulty.
The Hall of Wardens remembers.
