Idle Online Universe RPG

Hi,
I have a question. My Guildmate have now a total of 119% for Multicatch does that mean he can now catch up to 3 fishes with one try? Or why should it be smart to get more as 100%?

I do not really understand why I should buy/unlock the new Multi Fish orb. I get from trophys and VIP already 75%.

110% = +1 guaranteed, with a 10% chance for another +1.

250% = +2 guaranteed, with a 50% chance for another +1

Thanks.
My Guildmate posted me a Image from Discord, a User got x4 :O
So the Fishing Multicatch orb is useful
