Rokakaka

What this item is:
This item allows the user to randomize the bottom two stats of their stand. However, events can allow this item to randomize 3 stats instead. It spawns every 5 minutes with a 1 in 2 chance, so they are quite common.

The randomizing:
Stands in HFTB have 4 stats, and the bottom 2 / 3 get randomized. These are all the stats they could get changed to:

2nd stat: Attack Speed / Durability

3rd stat: Precision / Range

4th stat: Development Potential / Range

The 4th stat can only receive range if the 3rd stat doesn't already have it.

An example of the randomization:
STICKY FINGERS:

2 / 5 Destructive Power

5 / 5 Attack Speed

5 / 5 Precision

1 / 5 Range This is a generic Sticky Fingers build. It's got good stats, but if for some reason you want to change things up, you could use a Rokakaka. After using the item you could get something like this:

STICKY FINGERS:

2 / 5 Destructive Power

5 / 5 Durability

5 / 5 Precision

1 / 5 Development Potential These are pretty terrible stats for Sticky Fingers. That is why using this item is a risk, because things might not go your way and you'll just end up getting awful stats.
