Why would you want to increase your opponent's damage to your lineup anyways.. Maybe you got it mixed up? Like, "can you give me a list of ninjas who can increase the damage of mystery skill to my opponents" maybe?

I think he meant those ninjas, who are able to increase their opponents mystery skill cd.

But as far as i know we havent got those yet.

Cn got it with breakthroughs for example Swimsuit Temari (Mystery) or Hashirama Senju (First Hokage) (Chase)

90% sure that he is talking about the ninjas that increase the mystery cooldown of their opponent's ninja by 1 turn. As far as I know we don't have any yet that can do it but here's the list that I could find that may come eventually:

Jiraiya [Sage Mode] (Chase +1)

Hashirama [First Hokage] (Chase Y)

Tobirama [Second Hokage] (Chase Y)

Temari [Swimsuit] (Mystery Y)

Sasori (Chase Y)

Deidara [Edo Tensei] (Chase Y)

Pain [Shurado] (Mystery +1)

Pain [Gakido] (Chase Y)

Mei Terumi [Fifth Mizukage] (Chase Y)

Mifune (Chase Y)

We will never know.. OP already ran away

ah yes this is what i mean..

thx..

but all the ninja right now need BT to get that skill,

so only DUY and SHIZUKA can do without BT, idk when they will be release..
