How often is it?

Hey Mpgh,
How often is it would you win something "Permanent" from BG Extreme?
I solo it 2x this morning lol and I won 16Days Pike Bomb and 12 Hrs Berr Barbatos..
That sux can someone tell me how often would you win it?

It#s really rare, I think a chance of 0.05% ?

Just look at it like this - Your pretty lucky to get the pike bomb timed or barbatos timed in like 5 games. I usually don't get anything except exp.
