In NinChat, you can view the posts of various characters across Gamninjustri.
Neptune, Asuka, and the others can be seen posting here,
but you also have a chance to run into many other ninja characters that you won't see anywhere else in the game.
A lot of them happen to post some pretty funny things, so don't miss your chance to check in when you can.
Oh, also... Speaking to certain characters might make things happen!
Sub-events with Neptune and the others might occur, you might receive items, and you might get new requests, so make sure to say hello!
Sub-events that you unlock through NinChat give you a special chance to see the other charming sides of a character you might not see during the main story.
You can always watch any events you've already seen using "View Events" from the Kumotsu Shrine.
These are special items which can be obtained through battles and other places.
They grant characters various effects by placing them onto the "Spirit Gem Board."
By placing Spirit Gems of the same type into specific shapes, bonus effects will activate!
There are only 3 available slots on the Spirit Gem Board at first, but more will unlock as you level up.
You can also synthesize Spirit Gems that are the same level and type to create an even stronger Spirit Gem!
The Shinobi Base is where you can prepare your characters for challenging battles they'll face in dungeons.
There are a few functions that can be access here, so make sure to utilize them well before going off to your next fight.
You can check a character's level and parameters, as well as the Ninja Art Skills, equipment, and Spirit Gems they have set.
You can check consumable items, Spirit Gems, equipment, and sellable items in your inventory.
You can strengthen your characters by placing Spirit Gems onto the Spirit Gem Board.
You can set Ninja Art Skills with the ○×□△ buttons.
You can set your Ninja Weapons, Shuriken and Kunai, as well as Charms wielding special effects.
You can select a "Leader" and "Partner" to challenge the dungeons. Since you can't use "Formation" within dungeons, make sure to check who is in your party before deploying.
