Add Affix:
This effect is simple, but also one of the most powerful. It will simply add an affix to an item that has room for an extra affix.
The part where this becomes powerful is we can influence what is added using Tuning Prisms. For example, White and Blue rarity Gloves, Amulets, Weapons, and Rings can all be crafted on using Aggressive Tuning Prisms to guarantee Offensive affixes on every single added affix. This can create very strong gear very early on for very little investment, and should be a go to method for majority of players to get very strong gear.
Chaotic Reroll:
This option is the one players should familiarize themselves with the most as it is the best option for taking good gear and making it into great gear.
What it does is it will select a random affix and reroll that affix into another affix at random. However we can also use Tuning Prisms to influence what affixes are picked.
So for example, if you had a ring with Physical Resistance on it and 3 very good Offensive affixes, you can use a Protectors Tuning Prism to guaranteed that Chaotic Reroll will remove the Defensive affix and reroll it to another affix of any type that you would want instead.
Focused Reroll:
This reroll option has the same idea as Chaotic Reroll, but works a little bit differently.
If, for example, you had a ring with 3 Offensive affixes and the last affix was Life Regeneration and you wanted to roll into Lucky Hit Chance instead.
Because both of them are Utility affixes, you can use a Pragmatic Tuning Prism to guarantee that the Life Regeneration is not only picked, but will also guarantee the result that is rolled to be another Utility Affix.
Remove Affix
Remove Affix works in the same way that Add Affix does, but instead of adding it will take away an Affix. And we can pick what gets taken away with Tuning Prisms in the exact same way.
The only thing to note is that when you remove an affix, it will lower the rarity of the item as well, making it a good way to get basic White gear for other crafting methods.
Transfigure Item:
This will be your ultimate upgrade for late game, and how it will work will depend heavily between the two types of Tuning Prisms used.
If no Tuning Prism is used, it will modify the item with a random bonus, either positive or negative, and will render the item unmodifiable.
If an Enthropic Tuning Prism is used, it will remove the negative outcomes at the cost of also removing the best outcomes. This can make for a guaranteed power increase and is worth using when you don't want to gamble on getting a good outcome. Using this will render the item unmodifiable.
If a Kullean Tuning Prism is used, it will instead add a random aspect onto your gear. While there isn't a limit to the number of times you can reroll for a new aspect using this, they are extremely rare and should only be used on the very best gear. The item will remain modifiable if this is used. It cannot be used on Uniques.
Unique Power Reroll:
Using this crafting option will reroll the modifiable passive range of any Unique placed into it. While it is simple, it is worth noting that the materials needed to do this are very rare and should only be used on the very best gear.
