Planks are used during the Liberation of Mazcab raid during the battle with Yakamaru. 20 are used during the final phase where Images of Yakamaru will appear in the pools; 10 are used to block the stun and sharknado pools each after the mirages are reduced to 0 life points. They cannot be banked. They will drop to the ground underneath the player holding them when they die or leave the group.
This information has been compiled as part of the update history project. Some updates may not be included - see here for how to help out!
- Prior to 8 August 2015, these planks could be smuggled out of Yakamaru's fight if the player left their group or was kicked out by their leader.
- Before an update, the planks could be alchemised and disassembled, which made the fight impossible to complete.
