Shukuchi is potentially a really useful ability, but currently, the user interface makes it slightly cumbersome to use properly.

Currently, if the user targets an area outside of the maximum range of Shukuchi, the targeting reticle becomes purple and it is unable to initiate Shukuchi.

The minor change in UI that I would humbly suggest is that the user's targeting cursor be rendered unable to select positions outside of the maximum range of shukuchi. And when the user's targeting cursor exceeds the limits of Shukuchi's range, the destination reticle for Shukuchi will remain in a position that is farthest from the player's character model as possible but still in the direction of the user's cursor.

For instance, if a Ninja wishes to use Shikuchi to move to the North 20 yalms. The Ninja may place his mouse cursor on a position 25 yalms to the North of his character model, but the targeting reticle will remain exactly 20 yalms North of his character model and remain usable.
