After the update of 9/10/2018, its abilities were nerfed. +15 Jump Power was reduced to +10 and +4 Movespeed was removed.
The ability to jump from the Sunflower Field to the Rose Field with this isn't equal to the one available with +20 jump boost, as you need to do extra efforts to do it.
After the 9/10 update, this is currently the only hat that gives a jump boost.
This is the only hat in the game which does not grant damage reduction.
