Twinkling Titanite: This is an upgrade material from the game Dark Souls 3.
The Twinkling Titanite is used to upgrade unique weapons. You need one for a +1, two for a +2, four for a +3, eight for a +4 and a Slab for a +5.
The best way to get them is by farming Rock Lizards you can find next to the Great Bellfry fire at the Archdragon Peak, as that’s a decently high droprate.
This form of Titanite reinforces weapons, granting them great strenght. Ordinary weapons require ordinary material, but unique weapons will not improve unless the added power of this Twinkling material is added.
It causes no secondary effects and keeps the weapon strong albeit unique!
