Noob Raikiri Question

[Riku]

Raikiri (Lightning Edge)
Rank: S
Range: Close (0m ~ 5m)
Type: Offensive
Handseals: 3
Chakra Consumption: 3x High
Though little has changed in execution, the power of Chidori is now increased even further, no longer able to be withstood by normal means. The penetrative power of the Chidori is increased tremendously, but so too is the chakra cost and the toll it takes on the body. It is a more refined and powerful version of Chidori, Raikiri is capable of piercing through nearly any substance (up to the full length of the user's arm). Presuming the strike is not fatal, this technique paralyzes the opponent for a full turn. On top of this, once learned all Chidori sub-jutsu can be performed under the power of Raikiri.

Note: Other than its penetrative strength, this technique also ha a high probable cost that paralysis will occur to those struck by the full onslaught of this technique.

so I get that it lets you increase the power of other chidori sub-jutsu, but what's the chakra cost?

Do we just add x3 high to the sub-jutsu cost, is the cost just x3 high, or is the cost the same?

Help would be appreciated

The chakra cost would be 3x High. It simply means that if you learn the chidori sub-jutsu, and know Raikiri, you can perform the sub-jutsu for Chidori, free of additional cost, simply by using Raikiri.
