Rule 1
Farm until a 10-pull feels cheap relative to your balance — the 850-Coin bulk pull is 15% cheaper per summon than ten singles.
Alliance Tower Defense Coins & Summon Guide
How Summon works in Alliance Tower Defense!: 100 Coins per pull, 850 for a 10-pull, documented rarity odds from 50% to 0.1%, the 1,000-pull Mythic pity, and the pull discipline that keeps your Coin budget alive — checked 2026-10-15.
Quick answer: farm to bulk pulls, ignore pity folklore
This page is the verified Coins Summon loop: a budget checklist, an explicit unavailable state where costs and rates have no source, and the pull timing that follows.
Summon ×1 costs 100 Coins and Summon ×10 costs 850 Coins — a 15% per-summon discount, which makes the 10-pull the default unit of summoning. The documented odds are unforgiving: 85% of pulls land at Basic or Uncommon, Legendary is 1%, and the Mythic is 0.1% with a community-documented (never officially confirmed) pity of 1,000 pulls. That math is the whole strategy: farm until a 10-pull is cheap relative to your balance, pre-set a session cap, keep a third of your Coins in reserve, and pull after an X2 farming window — never before it.
The odds table
What each pull can deliver
Community-documented odds, checked 2026-10-15. Exclusives and event units are NOT in this pool — they come from crates, the shop, the Spin Wheel, and events.
| Rarity | Chance | Expected per 10-pull | Units |
|---|---|---|---|
| Basic | 50% | 5.0 per 10-pull | Speaker Man |
| Uncommon | 35% | 3.5 per 10-pull | Camera Man |
| Rare | 10% | 1.0 per 10-pull | Large Speaker Man, TV Man, Camera Woman |
| Epic | 4% | 0.4 per 10-pull | Large Camera Man, Large TV Man, Plunger Camera Man, 10M Camera Man (event) |
| Legendary | 1% | 0.1 per 10-pull | Titan Speaker Man, Titan TV Man, Dark Speaker Man, Speaker Woman, 10M TV Woman (event) |
| Mythic | 0.1% | 0.01 per 10-pull | Titan Speaker Man 2.0 |
Discipline
The five summoning rules
The same budget logic the fan strategy guide teaches for gacha-style modes.
Rule 2
Pre-set a pull cap for the session and keep about a third of your Coins in reserve for patch refreshes.
Rule 3
Pull after a 2x Coins farming window, not before it — more Coins per hour means more pulls per session.
Rule 4
Test each new unit on a 1-player Easy City run before taking it into Insane or Crazy.
Rule 5
Use Auto Sell to convert duplicate low-rarity pulls into Coins instead of inventory clutter.
Worked example
What 5,000 Coins of pulling actually buys
At documented odds, five 10-pulls (4,250 Coins) plus 750 reserve.
Fifty pulls at documented odds breaks down to roughly 25 Basic (Speaker Men), 17–18 Uncommon (Camera Men — welcome), 5 Rare, 2 Epic, 0.5 Legendary, and a 5% chance of even one Mythic. That is why the community consensus is blunt: early pulling is for widening your roster (Camera Men and one Epic carry), and the Mythic chase is a long-term project funded by the Insane/Crazy economy — or shortcut by trading. The 0.1% Mythic rate also means the 1,000-pull pity, if it exists as documented, is roughly 85,000 Coins of worst-case insurance.
FAQ
Summon questions
How much does a 10-pull cost in Alliance Tower Defense?
850 Coins, versus 1,000 for ten single pulls — a 15% per-summon discount. Farm to bulk pulls unless you are one pull from a specific goal.
What are the summon odds?
Community wiki documentation lists Basic 50%, Uncommon 35%, Rare 10%, Epic 4%, Legendary 1%, and Mythic 0.1%. The developer has not published official rates. Exclusives (Scientist crew, TV Woman, DJ Speaker Man) and event units are not in this pool at all.
Is there a pity system?
The community wiki documents a pity of 1,000 summons for the Mythic Titan Speaker Man 2.0, but the developer has never confirmed it. One fan guide puts it bluntly: assume every pull is independent and treat pity as unverified folklore until the developer speaks.
Does x2 LUCK help summons?
The 199-Robux x2 LUCK pass affects summon outcomes, but its exact magnitude is unpublished — community guidance is that it does not conjure specific units on demand. It stacks with nothing in particular; it just shifts the same odds.
What should I do with duplicate units?
Use Auto Sell (added August 20) to convert them to Coins without leaving the summon screen. Half your pulls will be Basic Speaker Men — that is the odds working as documented.
Step-by-step: the pull session
- 1. Farm until a 10-pull (850 Coins) is cheap relative to your balance — the 15% bulk discount does the work.
- 2. Pre-set a session cap: the number of 10-pulls you will accept before stopping.
- 3. Keep about a third of your Coins in reserve so a crate or event never forces a drought.
- 4. Pull during an X2 farming window, never before one — the Coins you save are the next pull.
If you're stuck
Long droughts are expected math, not bad luck: 85% of pulls land Basic or Uncommon and the Mythic sits at 0.1% with a community-documented (never officially confirmed) 1,000-pull pity. Re-read the odds before blaming your account.
Common mistakes
Buying single pulls at full price, treating the pity number as an official guarantee, and pulling the moment a session starts instead of after the X2 window opens.
