Frequently asked questions

How do you get the 6th builder in Clash of Clans?

Reach Builder Hall 9, build the B.O.B Control and upgrade it to level 5 by gearing up a Home Village building, getting a Builder Base troop to 18, a Builder Base defense to 9 and your Battle Machine and Battle Copter to a combined level of 45.

What is the cheapest gear-up for B.O.B?

Usually the Cannon: it needs Cannon level 7 and Double Cannon level 4 and costs 1,000,000 gold with a 2-day gear-up.

Which troop should I upgrade to level 18 for B.O.B?

Whichever of your Builder Base troops is closest to 18 — the 6th Builder Timeline picks it for you. Every troop needs Star Laboratory 9 for level 18.
