Builder's Training (B.T.) is where players must utilize their Gunpla Parts & Pilots collection to obtain Build Points (which then is used to exchange for Marks). Amassing Build Points ASAP is extremely important as it dictates your rate of obtaining Marks that drastically increases your Gunpla's Parameters. Builder's Training refreshes daily with each Training Regimen demanding randomized list of conditions, often producing problematic combinations for players to solve.

Players must build Training Gunplas to fit four conditions (Attribute, Word Tag, Job License, CPWR) where fulfilling each multiplies the final Build Points output, making it essential to stack the bonuses as many as possible.

There is an option to use Boost Training per Gunpla to increase the final output by two times, available to be used seven times per week. It is recommended to use this feature whenever you can reach the maximum multiplier for Build Points.

When building for Builder's Training, it is generally recommended to start by ticking off the Job License requirement with an AI Pilot, then picking up Gunpla Parts to clear off Attributes and Word Tag. If you don't have particular Parts with both the Attribute and Word Tag, split the two requirements between other Parts you can equip.

For example, with Training Regimen that requires Attribute [X], Word Tag [Y] and Job License [Z]:

AI Pilot (Job License Z [+ Attribute X and/or Word Tag Y if possible] )

-> then

Parts (Attribute X & Word Tag Y)

-> if you don't have 4~5 Gunpla Parts of this particular combination

Parts (Attribute X) + Parts (Word Tag Y)

After a particular set of Parts has been used for clearing off each Training Regimen, they can not be used again until the weekly reset at Monday 5am JST (same time as weekly Arena closure). This poses a puzzle challenge for the players to conserve and strategize which Parts to use first and last.

As the week progresses, most players will eventually be forced to either cut the CPWR condition at 100k milestone or skip one of the other condition. It is recommended to aim for 100k CPWR while fulfilling other three conditions for optimal gain of 200 Build Points.

300K + Attribute + Word Tag + Job License = 300

100K + Attribute + Word Tag + Job License = 200

100K + Missing one of the three conditions = 100

10K + Attribute + Word Tag + Job License = 100

100K CPWR can be typically reached with most of the used Parts being ☆3 lvl40, and filling the gap using unused ☆4~5 Parts to reach the milestone. Remember that you also have the option to submit incomplete Gunplas to conserve the Parts collection for future uses.
