Construction Corps
Also known as "Construction Team" or "bulldozers", those items are obtained through quests and the item shop, and are used for LBAS unlocking and upgrading.
Uses
Bulldozers are currently used for 2 LBAS related upgrades :
- They are needed for unlocking the world 6 Land-bases
- In order to use the LBAS at World 6, the quest F43 has to be completed.
- Each bulldozer will open one LBAS in this world, so up to 3 bulldozers are needed to open the 1st, 2nd, and 3rd LBAS.
- The need to open the 3rd LBAS is arguable, for more info, read: Troubleshooting
- They are needed for unlocking the world 7 Land-bases
- In order to use the LBAS at World 7, the quest B175 has to be completed.
- Each bulldozer will open one LBAS in this world, so up to 3 bulldozers are needed to open the 1st, 2nd, and 3rd LBAS.
- The need to open the 2nd and 3rd LBAS is arguable, for more info, read: Troubleshooting
- For upgrading LBAS groups from each world (events, worlds 6 and 7 for now, world 5 soon) from level 0 to 3, using the Land Base Maintenance menu.
