Summoning Rate Meta — 0.31% Heroic Confirmed

Destructoid, GameRant, Earnaldo, and ofzenandcomputing publish identical drop-rate ladders for Retro Tower Defense summons: Starter 51.39% / Rare 35.97% / Epic 10.28% / Legendary 2.06% / Heroic 0.31%.

GameRant's Feb 2026 meta update crowned 4x4x4x4 as the best unit in the game, with Noli, Mage, Helper Bot, Rocket, The Visitor, Jeff III, c00lkidd, Darkheart, Headless IV, Ellernate IV, Disaster Dude II, Guest 666, Crazy Robloxian, Doombringer, and Tycoon all in S-tier.

Helper Bot +60% buff stacks multiplicatively across players (community-reported 240% cap in 4-player co-op). Combine with Hyper Buff (event-only) for a +290% theoretical cap.

Use the new Summon Planner tool to compute Tix payback time for a 95% Heroic pull at base Luck (~95,500 Tix) vs 3x Luck + TRAFFIC boost (~32,100 Tix).
