I think it will be...but it might get annoying or quite helpful.
Plus, now that I think about it... once I scroll my water and get my earth to 180...I might be able to do RB quest solo, I won't need to buy it.
Can someone see if I can? Here's my team:

FlameBrag: Fire Killer LV 95
ATK: 1543
DEF: 653
SPD: 434
Alice: RB Niss LV 68
HP: 3089
SP: 2120
MAT: 1738
Weapon: Spirit Fork +4

Sakuri: Fire Killer LV 81
ATK: 1853
DEF: 555
Weapon: Heavy Spear with 26% Bomb Diamond

WaterWizX: Water Wit LV 83
DEF: 704
MAT: 860 (777 without but it might be more after I scroll some WIS to INT)
SPD: 628
Mikuru: RB ShaSha LV 83
MAT: 560 (I think it was 515 without eqs)
SPD: 598

Then...Plus my Earth at lv 180 (I did some Doala and Wlo calculator to get these stats since she's not RB yet: (this is with eqs on)
KanaZaki: Earth Wit LV 81
DEF: 790 CON: 180
MAT: 1042 INT: 253
MDF: 514 WIS: 49
SPD: 453 AGI: 66

MAT: 959 before RB (752 without eqs)
