Bubble Gum

There are two types of Bubble Gum: regular Bubble Gum (Item ID: 12210) which says that it increases drop rates to 200% (2x the standard rate) and HE Bubble Gum (Item ID: 12412) which says it increases drop rates to 300% (3x the standard rate). Neither of the descriptions are to be taken literally. They do not increase the actual drop rates.

When using Bubble Gum (regular), killing a monster will behave as though you killed it 2x, giving you two chances of obtaining the item. Say you're hunting Lost Soul (drop rate: 10%) with HE Bubble Gum. This is the process: As you can see, the drop rate is still 10%, but it's as if the gum gave you more chances of obtaining the item.You can obtain Bubble Gum from Lucky Me and from the Collector Keeper. You can make HE Bubble Gum from the Guardian Keeper.
