Stand Disc Fusion

Stand disc fusion is a gameplay element allowing you to combine the levels and passive abilities of multiple stands into one.This can be done using Crazy Diamond's active effect to fuse 2 stands at a time,or DIO's Bone to fuse up to 9.

Base Stands
When fusing stands,(in most cases)the stand you select first remains your base stand.This means that even though it gains the passive effects and levels of the stand you fused it with,it still has it's original name,original attack,and active effect.For example,A Kraftwerk +1 fused with The Fool +3 will result in Kraftwerk +4 with The Fool's passive effect(as well as it's own).The disc that remains the base stand is the first one you chose(if you're using Crazy Diamond's active effect) or the first disc you insert into DIO's bone.

Ability Slots
Each stand disc only has a small number of slots for passive abilities.You can check these slots by selecting the stand disc in your inventory and choosing the bottom option.Once a stand disc's slots are full,it can not gain any more passive abilities.Using a stand arrow increases the amount of ability slots of all your currently equipped stands have by one,but the absolute maximum amount they can have is 8.If a stand ends up with an ability you don't want,you can erase abilities with Boy II Man's active effect.

Base Only Stands
A few select stands can only act as base stands.This mostly applies to stands that change the way you attack,like Sticky Fingers and Diver Down.Stands can still be fused with them,but they must remain the base.

Creating New Stands Via Fusion
There are some unique stands that can only be acquired by fusing 2 or more discs.The list of possible fusions are:
 * Weather Report + White Snake = Heavy Weather
 * The World + Star Platinum = Star Platinum The World
 * Whitesnake + "4 Beetles (Hermit Purple + White Album + Death 13 + Yellow Temperance)" = Made in Heaven(must be done using DIO's Bone)
 * Killer Queen + Sheer Heart Attack = Bite the Dust(bite the dust can be found randomly as a drop too,this is just an alternate way to acquire it)
