Ninja: Walk in shadow.

[Eardstapa]

I understand where you're coming from, but somehow I doubt that they would make a signature move of a ninja so useless. Then again, this is SE we're talking about, so anything is possible.

Suiton allows the usage of SATA without hide, SATA is on a 1 minute cool down.

EDIT: Also, because I had to test the, "Even if you're detected stealth won't break." Theory... The second you are detected, stealth breaks with Disciples of Land. So if raid bosses have special sight, like I assume, it will break instantly, meaning no opening TA without Suiton.
