Legendaries and roamers

None of these lives in the grass. The Ley Line Sanctum holds one at a time and rotates; the roamers move about the region and have to be chased. Neither can be met before the League is finished.

The Sanctum pool 66↑

One at a time, in rotation, at Lv. 100. Every player gets one attempt per rotation.

Roamers 44↑

These move about the region rather than waiting in the Sanctum: they turn up while searching the route they are on, at Lv. 70, one search in a hundred.
