U need 4800 seals to get him , be lucky.

4800 = 600.000 coupons

or 300.000 if u get 50% off events.

Better u try buyinf him at Events, or wait a loooooot

by year u got something like 200 free seals, and maybe 30 seals by month , soooo : its , kind off +/-560 seals by year . lets be positive, and say u got 800 seals by year. It will take 6 YEARS for you to take him for free... if you only invest in treassures who got him.

So beeing really positive , u probably never get him beeing free dude ... unless u got frags on events.

Orrrrr , you can invest every seal on edo treassure, who drops his frags every 30 - 40 seals. U will need 2800 seals, = 350.000 coupons , 175.000 coupons 50%off , or something like 3,5 - 5 years
