How to GET LIL DOOMBRINGER in Battle Bricks
If you want to maximize your unit collection and flaunt an exclusive badge of achievement, learning how to GET LIL DOOMBRINGER in Battle Bricks will be your top priority here. Lil DoomBringer is one of the top battlers and a limited special badge item that opens up after you complete the complete Chapter 1 under 3-Star Mode. This is far from a casual feat; it demands strategic upgrades and proper execution.
The progression should be clarified as first completing Chapter 1 in 1-Star Mode, then doing it in 2-Star Mode, and finally achieving the demanding 3-Star Mode. I would highly recommend that Chapter Mode 1, Mode 2, and Mode 3 be cleared in 1-Star Mode with utmost priority. This is crucial to unlocking base upgrades and, more importantly, having the ability to improve your core unit abilities in which makes the successful completion of Chapter 1 in 3 Stars much more feasible.

Essential Pre-Requisite: XP Farming Strategy
My personal struggle in the beginning with the feat of getting 3 Stars was that it was hard. And it dawned upon me that the challenge was not just about unit placement: it was really all about the raw power of my units. Therefore, in all honesty, farming XP is the x-factor towards anything connected to GET LIL DOOMBRINGER in Battle Bricks. XP is the currency required for upgrades to your base and unit levels.
Thanks to making myself way too powerful, I will now reveal the ultimate XP farming method to power through the stages in no time.
The Ultimate AFK XP Farm
Map to Beat: Use Ultimate Painful, or any stage you can beat consistently with ease.
Required Unit: The Speed Battler (unlocked later in the chapter costing 100 Bricks).
Setup: On the map, place your Speed Battler or any combination of rapidly killing units.
Automation: Map your mouse cursor to the Replay button and run an auto-clicker.
Result: The auto-clicker keeps on replaying the map, summoning your Speed Battler, and auto-clearing the stage over and over again. Each successful run nets around 5,000 XP in under a minute, helping you quickly max out your units and base while AFK.

Walkthrough: Early Stage Unit Combinations
For players new to the game, the stage structure is very important for consideration. Chapters are divided into five to ten stage intervals, where players are awarded Bricks to be used for upgrades or purchasing units.
For a new player, it is essential to learn how to do an early meat shield strategy.
Stage 1-5 Strategy: The Troll & Sword Combo
After clearing Stage 2, you unlock the Troll Battler. The Troll acts as a Meat Shield, literally blocking enemy units from attacking your DPS.
The Sword Battler is arguably one of the best early game fighters in the game, especially after upgrades.
Place the Troll Battler (the meat shield) in the front lane and immediately behind it the Sword Battler. The Troll absorbs damage while dealing high damage output from the Sword Battler, which sometimes one-taps enemies with a couple of upgrades. The strategy is vital in your early-game progress.
Stage 6-10 Strategy: Adding the Slingshot
Upon completing Stage 5, you unlock the Slingshot Battler. This battler is a long-ranged DPS unit best for packing and entropy help.
Placement: In the front lines, use your Troll/Sword combination and place the Slingshot Battler right behind. The Slingshot attacks from the distance and remains safe from harm as long as your meat shield holds.
Important Note: Always use the Cannon on big crowds or armored targets to clear a path for your units.
Upgrading Base Wisely for 3-Star Mode
Getting the needed accrued XP and Bricks to benefit your base wiser was to GET LIL DOOMBRINGER in Battle Bricks. Many new players neglect this, greatly delaying their progress.
Always prioritize Bank Income ahead of Base Health in the early game. Focusing on income lets you place units quickly and upgrade them within a match, which is the real key to winning.
Must-Have Base Upgrades (By Order of Priority):
Income Banking: Maxing this out increases profits drastically over time within a match, allowing for even faster unit spamming.
Early Income: Increases your starting cash, vital for immediately placing key units like the Troll or the Sword Battler.
Unit Limit: Increases the amount of units you can put on the field, which is really important for later, hard stages.
Unit Recharge Rate: Get to place your units faster after having them disabled or at the start of the round.
Unlocking the Speed Battler and Finishing Chapter 1
The Speed Battler (also known as Speed Battler) is an S-Tier unit in the game, essential for fast completion, as well as AFK XP farm.
Acquisition: The Speed Battler is unlocked around Stage 13 and costs 100 Bricks.
Speed Battler Strategy: With any new upgrades (from XP you farmed), the Speed Battler just zips in and flattens enemy units. At best late in-game, he is so broken you might find you use few other units for almost every single stage. For the rest of Chapter 1 stages, do focus on spawning as many Speed Battlers as you can.
Thus do XP farming and upgrade your way into ensuring strong enough units to win out in the difficult 3-Star stages that finally enable you to GET LIL DOOMBRINGER in Battle Bricks.
