Além de ser soltado, um fragmento individual pode ser criado ao combinar os três outros tipos de fragmento. Por exemplo, se um jogador faltasse um Fragmento do Sol mas tivesse um excesso de todos os outros tipos, o jogador poderia combinar um Fragmento de Vórtice, um Fragmento de Nébula e um Fragmento de Pó de Estrelas para criar um Fragmento do Sol. Isto é feito em um Manipulador Antigo.
It is likely that the ability to craft a single type of fragment (Solar, for example) from the other three fragment types (Nebula, Vortex, and Stardust, in this case) was implemented due to the arduous process required to collect each fragment. For example, being a single Solar Fragment away from crafting the full set of armor would otherwise mean that the player had to again fight the Lunatic Cultist and the Solar Pillar. Furthermore, it allows players to craft items that require all four types of fragments, such as the Super Healing Potion, prior to taking on the Moon Lord.
The fragments each correspond to a weapon class. Solar Fragments are used for melee weapon users, Nebula Fragments for magic users, Vortex Fragments for rangers, and Stardust Fragments for summoners.
Lunar Fragments are not affected by gravity, similar to souls.
