What to build first in Builder Hall 3

You may know that farm in this modality isn’t easy, we won’t linger on the question of gold and elixir as we have widely talked about it in the article on How to Farm in the Builder Base. This is why it is extremely important to rationalize and maximize the amount of resources we can unlock on a daily basis. It goes without saying that investing gold and elixir on buidings or upgrades that may turn out to a waste would cost a lot in terms of time and wins in Versus Battles. Here’s what to build or upgrade with prioritize.

How to use gold in Builder Hall level 3

First of all, upgrade Elisir collector to Level 3 (low costs and times), because you’ll get bigger amount of elixir.
After that, the first rule is to defend themselves! That’s why it is very important if not essential to invest the Gold in defenses by following this order:

1. Hidden Tesla,
2. Build the new pieces of wall available (at least 2 rows at beginning)
3. Build at least 1 Mine and set it to air (while waiting to build firecrackers).
4. Spring Traps (at least one),
5. Firecrackers (Given the high cost we preferred to wait for the investment),
6. Upgrade Archer tower and Double Cannon,
7. Upgrade Hidden Tesla,
8. At your choice, buy the Crusher or continue upgrading cannons.
9. Max Elixir Collector (negligible)

How to use elixir in Builder Hall level 3

The elixir has a great potential in this game mode and will serve you mostly to strengthen and unlock the abilities of the new troops. Here is the order and what to do first with Elixir:

  1. Upgrade Builder Barracks until max level: you’ll unlock Boxer Giant and Beta Minion (very important!)
  2. Buy a new army camp (the third costs too much for now),
  3. Upgrade Star Laboratory until level 2 (we’ll upgrade it to level 3 soon).
  4. Max Gold Mine (negligible)

Star Laboratory: What to upgrade first

The offense is very important in this game mode, so you have to invest heavily on the upgrading of troops in the Star Laboratory and allow them to unlock at least Level 2 and therefore the special abilities; here is the upgrade order:

  1. Upgrade Star Laboratory to level 2,
  2. Ignore the boost of Raged Barbarian and Sneaky Archers (only at beginning),
  3. Upgrade Boxer Giant and Beta minion to unlock the hidden ability (Essential, above all, Giant Boxer’s; give him priorities),
  4. Upgrade Star Laboratory to level 3,
  5. Upgrade another time boxer giant to level 4,
  6. Upgrade sneaky archers,
  7. Upgrade Beta Minion,
  8. Upgrade Raged Barbarians.

These are the two important steps to follow, then you can engage yourself in upgrading and purchasing all the remaining buildings such as Pink Elisir Storage and Gold Storage, before upgrading Builder Hall 4.
Gem Mine is currently avoidable, as it has a very high cost for reparation and generates just 2 gems a day (an obstacle can yield up to 6 if not more).
