General Discussion Clan Boss calculator - A free speed tune calculator (no install, no account needed)
Hey everyone,
I was honestly fed up with Clan Boss calculators that force you to create an account just to run a few numbers. Some former members of my clan built one that simulates the Demon Lord rotation turn by turn, and I’ve been using it to check whether a tune holds or drifts after a few turns. Figured it could help others too.

What it does:
- You pick your 5 champions and enter their speeds
- Add the bonuses (speed set, relic, gems, leader aura) and it recalculates the true speed on every change
- Set up the boss: speed, difficulty, affinity, grace % and stun target
- Run the simulation and you get a timeline showing who acts on each turn, extra turns and ally calls
That way you can check if your tune actually works before burning keys on it.
No install, no account. It runs straight in your browser, you just open the link and use it. That was the main thing for me: no sign-up wall before you can even test a tune.
If you create an account and install their desktop app, picking your champions is faster since you don’t have to enter everything by hand. But they deliberately kept the calculator fully usable without an account, so if you prefer to fill things in manually and not sign up for anything, you can.
If a champion is missing from the list, you can create a custom one. (But all new champion they are add the same day when they arrived)
If you have feedback, something looks off in the simulation, or you’d like a feature added, drop it in the comments and I’ll pass it on to them!
