If you want to get there faster, be prepared to sink all of your CWL medals into hammers of heroes for the battle machine (you have at least 20 levels to go there), hammers of fighting for the cannon carts, and hammers of building for the mega tesla and multi-mortar.

Likewise, how do you rush the builder base to get Otto? Just stick to the OTTO checklist while rushing and you'll get there as fast as is possible. One cannon to lvl 4, one archer tower to 6, mortar to 8, Mega Tesla to 9, Cannon Carts to 18, and Battle Machine to 30.

The O.T.T.O is unlocked by building the O.T.T.O Hut then upgrading it to level 5. The hut is not upgraded with resources or time, but rather certain tasks must be completed. In order to obtain O.T.T.O Hut level 2 you must gear up all three types of buildings (Cannon, Archer Tower, and Mortar) in your Home Village.

How long does it take to get to Otto Hut?

The O.T.T.O Hut is a building unlocked at Builder Hall level 9. The O.T.T.O Hut does nothing when initially built, and will only serve as a distraction defensive-wise then. However, it houses the O.T.T.O which can only become active when the O.T.T.O Hut is upgraded to level 5.
