It extends resta range and gives a free resta, both of which aren't that good.
30% range isn't jack (and pretty sure it a typo), resta merge, and Tyrell's parasol buffs it by 100% for example. Still Male FO can at least use this.
Its a low level resta for the special, which can be useful, but not a full item slot that you have to balance.
It is bad at fighting, no combo for one.
but people say it worth 5 or so. Its nice in cool factor so I'll back that
