Reinforcement Expansion

Introduction

The Reinforcement Expansion is a consumable item added alongside the Summer 2015 Event that allows you to reinforce a ship to permanently add an additional utility equipment slot. For example, you can equip a reinforced ship with damecons without compromising their equipment loadout.

• Your Kanmusu must be at least Level 30 to install a Reinforcement Expansion.
• The additional equipment slot given by a Reinforcement Expansion will remain with the ship permanently; remodels will not remove it..

• Reinforcement Expansions can be obtained through either normal gameplay, such as events and quests, or the cash shop for 500 DMM points.

Use

To use the Reinforcement Expansion:

A text box which indicates that a ship may be given a Reinforcement Expansion

• Go into the equipment menu.
• Select the ship you wish to add give the Reinforcement Expansion to.
• Mouse over roughly the bottom half of the ship's card. You should see a text box appear; once you do, click on it.

The Reinforcement Expansion confirmation prompt

• Press the left button to confirm the application of the Reinforcement Expansion (press the right button to cancel it).

• The additional slot is shown in the red circle.
• The additional slot is carried over when a ship is remodelled.
• The additional slot with an Emergency Repair Personnel equipped inside of it.

1/3

• The extra slot will appear ontop of the right side of the ship card.

Allowed Equipment

Only certain pieces of equipment can be placed inside the additional slot given by a Reinforcement Expansion; the equipment allowed is dependent on the ship that was given the extra slot. Equipment placed inside this slot functions as if it were placed in a normal equipment slot.
