Your CWL month,
from signups to boom.

BooM BoT runs Clan War League for Clash of Clans families on Discord: collect signups, build rosters across every clan, get warned before you roster a liability, publish with pings and DMs, and track who actually showed up.

Features

Everything the spreadsheet used to do. Nothing it couldn't.

Built by CWL leaders who got tired of pinned messages, copy-pasted lineups, and finding out on war day that a roster spot went to someone who never attacks.

Signups

One post, one click to sign up every linked account. Opt-outs are recorded too, so "didn't answer" and "said no" never get confused again.

Multi-clan roster builder

A live interactive panel: tab between clans, filter by town hall, search by name, move whole lineups between clans. Two leaders can build different clans at once.

Player vetting

Every add is checked against real war history: star form, missed attacks, league experience, tenure, and flags. Warnings advise; you decide.

Publishing that behaves

Announcements ping once. Reminder posts update in place as players move clans. Every rostered player gets a DM with their placements and a button to request changes.

Account linking

Self-service with API-token verification, a public claim board with leader review, bulk import from ClashPerk exports, and automatic mirroring of ClashPerk links.

Flags that follow the player

Bans, strikes, and warnings attach to the person, not the account — alts included. With a built-in dispute process, so records stay fair.

How it works

One dashboard, five steps a month.

Sign up

Post the signup message. Members opt in or out for the month with a click.

Build

Assemble each clan's lineup in the live builder, with signups surfaced and town halls filtered.

Vet

Get warned about shaky war records before the lineup locks — not after the no-show.

Publish

Announcements, live reminder posts, and placement DMs go out in one action.

Track

Live markers show who moved to their assigned clan. Amend the roster without re-pinging anyone.

The difference maker

Know before you roster.

BooM BoT builds a history for every player it sees — CWL stars, missed attacks, benched rounds, clan tenure, trophy activity — and reads it back to you at the exact moment it matters: while you're adding them to a roster.

  • Relative to the league. A Crystal-fine record can still earn a caution for a Champion roster.
  • Advisory, never blocking. Serious warnings pause for an "Add anyway" — the leader always has the final say.
  • Fair to newcomers. No history reads as unknown, never as guilty.
  • Cross-server memory. History and global flags travel with the player, not the server.
Vetting check — example
DarkLord99 — 2 missed attacks in the last 3 seasonsAdd held. Confirm with Add anyway, or Cancel.
Slayer — averaging 1.9 stars vs Master II averageBelow par for this roster's league. Worth a look.
NewGuy — no CWL history yetFirst season on record. Low confidence, not a judgment.
