Fixed a couple things wrong with gacha, should work a lot better now …

…and it's definitely more lower rate. Before you would always get weapons and armor because the if statement was wrote wrong.

Default rates:
Have to pull 10 times to try and gacha a card.
12% for weapons and armor
10% for a card.
