Support Tier List - Retro Tower Defense

July 2026 Support Meta Overview

Support towers multiply your DPS output through buffs, debuffs, shields, and utility—not raw damage. This tier list ranks Retro Tower Defense support units after the July 2026 Summon Overhaul and trait reroll patch.

One well-placed S-tier support often outvalues a second DPS tower on Hard and Endless because buff radius and debuff uptime scale every nearby damage dealer. Budget one support slot before stacking duplicate Mage copies.

Pair this page with our DPS tier list for full loadout planning and the farm tier list when deciding whether to slot economy towers alongside support.

S-Tier: Helper Bot

Helper Bot dominates S-tier as the only team-wide buff tower with radius large enough to cover a standard six-tower loadout from a single central tile. Damage and attack speed bonuses stack multiplicatively with Mage AoE and Noli burst windows.

Place Helper Bot at the geometric center of your map layout—Crossroads plaza, Doomspire mid-platform, or Chaos Canyon hub—so every elevated DPS tile sits inside the buff ring. Upgrading Helper Bot during early waves pays off before boss checks because buffed Minigunner or Scout can hold until Heroic towers deploy.

Trait rerolls on Helper Bot should target buff duration or radius extension traits. Even a Rare-tier buff tag on Helper Bot outperforms an extra B-tier DPS without support coverage.

A-Tier: Rocket and Hybrid Debuffs

Rocket earns A-tier as a slow and armor-debuff hybrid that sits between pure support and secondary DPS. Slowed bosses take longer in Noli execute range; armor shred amplifies Mage magical burst on Telamon and Yorick phases.

Rocket placement mirrors ranged DPS—elevated tiles with sightlines to boss spawn points. One Rocket covering the primary choke plus boss path often replaces a second debuff tower that would compete for the same central buff radius as Helper Bot.

Rocket pairs naturally with Helper Bot: buffs increase Rocket tick damage while Rocket debuffs extend the effective DPS window for every buffed tower in range. This duo is the standard support core when Helper Bot is your only S-tier support copy.

B-Tier: Dusekkar and Other Support

Dusekkar occupies B-tier with shield and damage-reduction utility that shines on boss waves with heavy AoE pulse mechanics—Yorick stomp, Telamon fire rings, and Endless escort explosions. Shields prevent leak deaths that would otherwise end runs during burst cooldown gaps.

Other B-tier support options include early-game Scout range extension when used as a temporary spotter before Heroic summons, and budget Epic units with minor slow tags that lose value once Rocket enters the roster.

Dusekkar belongs at ground-level chokepoints near your front line, not on elevated tiles. Position shields where escorts cluster so damage reduction covers the maximum number of incoming hits before your elevated DPS clears the pack.

• S-tier: Helper Bot
• A-tier: Rocket
• B-tier: Dusekkar, budget slow utilities

Central Placement Strategy

The July 2026 support meta revolves around one central Helper Bot anchoring buff radius while elevated DPS forms a ring around it. Think hub-and-spoke: Helper Bot at hub, Mage and Noli on spokes at high ground.

Rocket fills a spoke tile with debuff coverage overlapping both the main path and boss spawn lane. Dusekkar sits at the nearest ground choke spoke to absorb boss pulse damage. Never place Helper Bot on a map edge where half the buff radius wastes on empty terrain.

In multiplayer, coordinate so only one player runs Helper Bot while others bring DPS and Rocket debuff. Duplicate Helper Bots do not stack buffs—centralized support assignment prevents radius overlap waste.
