Astral Twilight!

Fancy name but we love Twilight, right?

Current stuff:

Twilight tools

Sword

Day: behaves like a normal sword.
Night: deals increasing damage the closer the moon is to the top of the sky.
On a full swing at night it heals the player — the closer the moon is to the top, the more healing (up to 1 heart).

Other twilight tools

Day: they burn and lose 3 durability per use.
Night: they work 4× faster.

Chargeable Twilight tools

All of them can be charged (maximum 1000 TE — Twilight Energy).
Charging rate: 1 TE every 1.2 seconds, only at night and under open sky.
Tools do not lose energy if the player is underground and not exposed to sunlight.

Sword

Day: if it has energy, it behaves like it does at night.
Night: deals 3× more damage, creates particles on hit, and heals the player by half a heart on a full swing.
Does not lose durability at night. During the day it loses durability only if there is no TE.

Other chargeable twilight tools

They never burn.
Day: if they have energy, they behave like it is night.
Night: they mine 4× faster and do not lose durability.

Twilight ore

Spawns only in the Dark Oak biome.
Drops Twilight Chunk.
Generation height: Y 16–128.
Cannot be generated in deepslate

Twyle plant

Grows only at night.
Seeds can only be found in Overworld dungeons (abandoned mineshafts, desert pyramids, jungle temples with a 25% chance.)

Twilight collectors

These are multiblock structures.

during nights with full moon phase collectors will collect liquid twilight every 50 seconds or so

They are used to collect Twilight liquids (normal and charged).

First type: normal
Uses Liquid Twilight Collector Block.

Pattern:

First layer
SSS
SSS
SSS

Second layer (above)
SSS
SXS
SSS

The structure size is 3×3×2 blocks.

S = Liquid Twilight Collector Block
X = air (this space will be replaced by Twilight liquid)

Second type: same pattern, but
S = Liquid Energized Twilight Collector Block

If regular sticks or a Twilight ore chunk are thrown into Twilight liquid, they turn into Twilight sticks and Raw Twilight respectively.

Charged Twilight liquid is used to transform
Twilight Chargeable Module (Incomplete)
into its completed version (just drop item into the fluid)

Two important multiblocks

Twilight Repair Multiblock
Build according to its pattern (see the images below).
Repairs items in the inventories of players standing nearby.

LAYER 1

LAYER 2

LAYER 3

Blocks used: Twi Structure Casings; Twi Calculating Blocks; Twi Repair Controller 

When constructed it will also emits effects showing that it is functionable 

Next multiblock -> 

Luna Infusion Multiblock

To build it, see the image below.

One single image

Blocks used: Twi Structure Casings(Quartzed); Starlight Relays; Luna Infusion Controller

The distance between squares is 2 blocks in height

while bottom square is on the same Y level with the controller

What does it do?
Try standing at the controller.

Maybe at night....

Maybe when the moon phase is full moon....

I hope you will find some way to implement this mod in your modpack -> It can serve as a good late game mod to grind/explore

Stuff that i didn't explain here can be viewed via JEI or similar mods
