Heroic Windmill

This facility allows you to transform your 4* R-grade and SR-grade heroes randomly to another hero. At LV2, this facility will allow you to transform 5* heroes as well with no additional cost.

Transforming heroes will require 100 Pal Points per attempt, up to 10 attempts per day. (These attempts are refreshed during the daily reset). They’ll also require the following essences:

R-Grade Heroes

Elemental Essence x50 (matches the hero’s element)

Elemental Essence x25

Elemental Essence x25

Elemental Essence x25

Elemental Essence x25

SR-Grade Heroes

Elemental Essence x100 (matches the hero’s element)

Elemental Essence x75

Elemental Essence x75

Rainbow Essence x50

Advent Essence x100

Again, I would like to emphasize that the transformation is entirely random. You can check the pool of heroes you’ll get by tapping the List button under the portrait of the hero you’ll transform to the left of the screen. You can get a new hero or someone you already have multiple copies. This is really something that you should be doing often as Rainbow Essences and Advent Essences (especially the former) are really hard to come by and will require either expensive trading and grinding.
