Endless TD's Relics of Ascension Is Its Biggest Update Yet

The Biggest Endless TD Update Ever Has Landed

Buckle up, defenders, because Endless TD just dropped the mother of all patches. Billed as "the largest update in Endless TD history," Relics of Ascension doesn't just add a few towers and call it a day — it reinvents how you build, loot, and climb in the tower defense roguelite. If the last big drop, the 0.5.1 PvP ranked overhaul we covered earlier, was about competition, this one is about *power fantasy*. And wow, does it deliver.

The headline is right there in the name: relics. But that's just the entry point to a sprawling new progression system that turns every run into a treasure hunt. Let's dig in.

Relics, Armor Sets, and a Glorious New Loot Game

At the heart of the update are 50+ base relics — permanent, auto-active legendaries that stack passive power onto your towers — plus 31 transformation relics that bolt damage scaling onto your talent nodes. They live in a brand-new drag-and-drop inventory complete with an equipment grid, ten relic slots, a backpack for spares, and three forges for rerolling, selling, and fusing your haul. Loot goblins, rejoice.

Then there are the ten themed armor sets — Inferno, Frostweaver, Bloodstorm, Plagueheart, Radiant, Arcanist, Stoneskin, Marksman, Tactician, and Necropath — each with six pieces. Complete a full set and you're rewarded with a meaty +150% tower damage bonus plus a signature effect, and you can run up to five complete sets at once. Mixing fire-spread, chain-lightning, and poison builds has never looked so tempting. The new Fusion forge sweetens the pot, letting you combine two relics into one via 14 named recipes like the Tempest Crossbow and Glacier Trident.

Ascension, Mythics, and the Hellfrost Goliath

This is where the "Ascension" half of the title earns its keep. Tier bosses (every 30 waves) now drop Mythic shards — collect five and you can forge an archetype-specific Mythic that grants +150% tower damage and keeps scaling with every extra charge. Each of the six archetypes — Marksman, Elementalist, Warlord, Tactician, Alchemist, and Ascendant — gets a signature Mythic that genuinely rewrites its playstyle.

My personal favorite addition? The Hellfrost Goliath, a six-tier ultimate tower born from merging the Inferno Phoenix with the Frost Mage. It inherits talents from both parents and tops out with a gloriously over-the-top Frostfire Apex. Fire and ice, together at last.

A New Colosseum Arena and Dynamic Storms

Craving a fresh challenge? The new Colosseum arena flips the script: enemies pour in from every side and circle forever instead of leaking, so victory means keeping the board under 300 simultaneous foes rather than plugging a single lane. It's a proper DPS gauntlet.

Speaking of gauntlets, the update adds dynamic weather. Hailstorms chip away at your towers over time, while an Electric Storm disables every tower aura for a full wave — the devs literally call it "a true DPS check." And for the speedrunners, game speed now goes all the way up to 5×.

Seasons Bring Competitive Bragging Rights

For the leaderboard chasers, Seasons are the new long game. Each named season (the first is "Alpha") resets competitive stats for a fresh climb, then immortalizes your run with a permanent Season Trophy Card snapshot when it ends. Career stats track your never-resetting lifetime achievements, and beefed-up profiles let you browse past Trophy Cards and flaunt your best ranks.

Quality-of-Life Wins and Smoother Multiplayer

Rounding things out is a mountain of polish: redesigned menus, a searchable Talent Constellation with jump-to-node, unlimited pausing, floating damage-over-time numbers, smarter tooltips, and seven new soundtracks. Multiplayer gets a major netcode overhaul to cut lag, plus Steam overlay friend invites with Rich Presence and strengthened anti-cheat.

The Bottom Line

Relics of Ascension is the kind of update that doesn't just expand a game — it relaunches it. Between the deep relic-and-armor loot loop, archetype-defining Mythics, a fresh arena, chaotic storms, and a full competitive Seasons framework, there's a staggering amount to chase here. If you bounced off Endless TD before, now's the perfect moment to jump back in. Your towers have never been this powerful, and the climb has never looked this good.
