Samurai Double Dot?

[ICountFrom0]

...You only have the one DoT, though, so unless you mean something very different from Iron Jaws, that would be wholly useless, except in that you'd then reapply Higan only at 1 minute, 3 minutes, 5 minutes, and 7 minutes.

First post includes the idea of having two dots.
Folks are quick to shoot it down.
I add the idea of having the dots function as per iron jaw as well, so the dots are self extending instead of self replacing, to see if that would be enough to make the idea viable.

... but somehow, I lost you with my suggestion?
