For the 4th anniversary, kage has released some new gear: a hairstyle, a clothing, and the back item. The most interesting one is the back item, which gives 50HP and 150CP back each turn, making it really good for CP regen. The gear total costs 1000 tokens, so it is really expensive. The items are as follows:
4th anniversary Hairstyle
4th anniversary suit
Description: 4th anniversary edition
4th anniversary backitem
Type: back item
Effect: Ninja Saga 4th Anniversary edition! Recover 50 HP and 150 CP at the start of each turn.
The back item is pretty cool, but I still feel that it is a copy of The Carnival Jiengu and the Golden Torch? Your thoughts?
