GENJUTSU

Tsukuyomi
introduced by Uchiha Itachi and proved as one of the deadliest genjutsu. Tsukuyomi takes away the victims consciousness and creates a pysically harmful illusion. the illusion itself only happened for a few seconds in the real world but it feels like it happened for days. the name comes from the Shinto goddess of the moon Tsukuyomi no Mikoto who was the kami of the realm of darkness, and the sister of Amaterasu and Susanoo no Mikoto

Amaterasu (Black Flames)
rather than a genjutsu, Amaterasu is an actual form of black flame that really burns. recently Sasuke found out that he can use his mangekyou sharingan to put out Amaterasu's black flames as well. however the usage of Tsukuyomi or Amaterasu will cause the damage of sharingan which will lead to blindness. the only way to reach sharingan final stage is by getting spare eyes from another sharingan user.

Susanoo
the third and final genjutsu that Itachi awaken from his sharingan. Susanoo is in form of giant God-like illusion who has the sword of Totsuka, also known as Sakegari's katana, is a weapon said to carry sealing powers. anyone and anything it pierces becomes trapped in blissful-like genjutsu for eternity or so the legend goes. the blade itself is enchanted with an incredible sealing technique, the ultimate counter of sword of Kusanagi.
