How to Reroll in Mechanic War Idle RPG

If you’re playing Mechanic War Idle RPG and want a head start, rerolling can be a great way to get powerful characters early on. Top-tier Mechanics, particularly those ranked S, can significantly speed up your progress in all game modes. Here’s a simple guide on how to reroll:

  1. Go to the Battle Interface, open the menu at the top right, and select Settings.
  2. In Settings, tap on Delete Account. Confirm by selecting ‘Yes’ when prompted to check the server connection.
  3. Your account will be instantly deleted (if unbound).
  4. Restart the game and complete the short tutorial (around 5 minutes).
  5. Claim all free Diamonds from gifts and coupon codes. Use your Diamonds in the Recruit section to summon Mechanics.

Frequently Asked Questions (FAQs)

What’s the best unit in Mechanic War Idle RPG?

Many players consider Commandio and Fire Deliver to be top-tier units because they get stronger as the game goes on and work well with almost any team. Blood Samurai and Yellow Dagger are also strong choices for dealing high damage.

Do I need tanks in every team comp?

It depends. While you might be able to succeed without a tank if you have powerful damage dealers or burst snipers, it’s generally much better to have at least one tank – like Green Beret or Red Heart – for boss battles and later stages of the game.

Are Hero-tier Mechanics worth using?

These units are really only useful at the very beginning of the game. Most ‘Hero’ units become weak pretty quickly, so you should swap them out for stronger ‘Ancient’ or ‘Legendary’ units as soon as you get them. Think of them as temporary helpers for the early part of the game.
