Slime Art Online
The Sacred Arts of Sword Art Online: Alicization in Tensura: spoken incantations, the Stacia Window, Divine Objects, Integrity Knights, the Sword Golem and dragons.
Slime Art Online brings the Underworld of Sword Art Online: Alicization into Tensura: Reincarnated. You cast Sacred Arts by speaking (or typing) the very incantations Kirito and Eugeo use, read the Stacia Window of anything that exists, wake the memory of Divine Objects and wear the armor of the Integrity Knights. The mod stands apart from the other add-ons of the series: all it needs is Tensura, GeckoLib and PlayerAnimator.

The spirit of the mod
Nothing is cast with a click. An incantation is composed command by command, just like in the anime:
System Call. Generate Luminous Element. Form Element, Arrow Shape. Fly Straight. Discharge.
Every element draws on the local Sacred Power — plentiful in a sunny clearing, scarce in a cave or a town, and quickly exhausted if you keep fighting in the same spot. What you can do depends on two authorities: System Control Authority (how many elements you hold, which arts answer) and Object Control Authority (which Divine Objects agree to wake their memory). Both rise as you fight and practise: see System and Object Control Authority.
