I don't get your question..^^
If it would give 1 100% Chance, everyone would have +24, or am I wrong?

As the name says, it gives you 250% more chance.

does the 2.5 luck potion give 100% to upgrade equipment ??

Let's say for exemple from +21 to +24 you will have 1% luck to get it.
With a 100% potion you would have 1% luck rate and with a 250% potion you would have 2.5%

I hope you get it

hello guys,i think there is a bit misunderstanding with the potions of fortune. i think it goes like this : the normal potion of fortune double the chances (200% ).so for example if there is 1% to upgrade from 21 to 24 the normal pf will make it 2% :). the 2.5 potion fortune will make it 1% *2,5 =2,5% and the x3 potion will make it t 3%. i think thats how it works the potions of fortune.i have seen a lot people who dont understand how it works .if i am wrong ,please correct me
