1- Turtle Sage Mode 2-Advantages-Increase Strength, Speed, Endurance, Durability, Defense, Strengthens Ninjutsu, Taijutsu 3-Disadvantages-Blindness while using the defense, slowest of the sage modes, need to be still while gathering energy, 5 minute of usage 4-Kaya Yoru 5- I think that a Turtle Sage Mode would be very interesting to use and see it in battle. Especially in the upcoming Sixth Shinobi War.
