when you start leveling skill up to around lv7++ the cost will be very high (it also depend on rarity - SSR cost more at lv10 than SR)

It always better to have this CE than nothing

But the time it come around again, u may have larger choice to burn for rare prism

(PS. there is also Chaldea Lunchtime CE that increase bond soon -  if u manage to have 5000 at the time it come, u can buy it instantly without spending rare prism)
