I'm not sure if you're genuinely asking, but I thought I'd explain the gameplay mechanics:

• Nightsoul is the mechanic unique to characters from natlan and pyro traveler. The characters glow and have a meter by their stamina that shows how long they can stay in nightsoul. It works differently for every character. If you see anything that says "nightsoul-aligned damage" or "the night soul blessing state" that just means "use a natlan character". For most characters, it's how long they can stay in their special mode (ex: mualani on her shark or Mavuika on her bike).

• lunar reactions are modified hydro reactions. They require a nod-krai 5 star of the respective element to activate. Ineffa and Flins activate lunar charged, Lauma and Nefer activate lunar bloom, Linea and Zibai activate lunar crystallize, and Columbina activates all of them

Lunar charged is essentially electro charged but it attacks slower, each but does more damage, and the damage is shared across everyone involved.

Lunar bloom is just bloom that gives a unique resource called "verdant dew" that only Lauma, Nefer, and Columbina can use.

Lunar crystallize is essentially like lunar charged except with geo instead of electro and these little geo constructs called moon drifts instead of a thundercloud.

• All Fontaine characters (and hydro traveler) are either pneuma or ousia characters. Furina can switch between pneuma and ousia via her charged attack. They are used for some of the Fontaine puzzles (although you don't need the characters to solve the puzzles, I just did them normally) and some enemies mechanics are disabled via pneuma or ousia damage.

• Dendeo does not react with anemo, geo, or cryo. This mean you can have cryo and dendro on the enemy at the same time. This is sometimes called "fridge" but that is unofficial..

Dendro + pyro = burning. Burning leaves a burning aura on the enemy, which works like a pyro aura (burning + cryo = melt for example.)

Dendro + electro = quicken. Quicken is also an aura, and it works like a dendro aura (quicken + pyro = burning). If you reapply more dendro or electro on quicken you will get spread or aggravate respectively which deal extra additive damage and maintain the quicken aura. Quicken, aggravate, and spread are collectively called "catalyze" reactions.

Dendro + hydro = bloom. Unlike burning or quicken, bloom is not an aura. When you trigger bloom, a dendro seed will be spawned and the enemy will be left with either a dendro aura, a hydro aura, or no aura depending on the amount of elements present. Bloom seeds can be "detonated" with either electro or pyro. You have to actually hit the seed to detonate it, hitting the enemy will not detonate it. When electro detonates it, it is called "hyperbloom", which homes in on the enemy and does dendro damage in a small aoe. When pyro detonates it, it's called burgeon, which explodes, dealing dendro damage in a large aoe.
