Lunar Lunatism currently has no downsides to using it, while giving them many, MANY benefits, however I do like this, you basically just give out the fact you're a vampire, for really good buffs that just make you downright scary to deal with. As it should be when fighting a vampire, however it is very strong given everything.

I have a suggestion to make this a cool skill to use, and the OP has the right idea but could be executed better.

The skill now costs 6M to use, but the buff it provides will last until your essence is drained to 0
The skill now drains 25 Essence per round (But this is doubled during the day, when the moon isn't showing)
Silvermists still uses 33% of your essence and then heals 3 per essence, but the healing effect is increased by 1.5x (balanced off by Lunar Lunatism costing essence per round)
You cannot use banquet during Lunar Lunatism.
After Lunar Lunatism ends, you gain a debuff that prevents gathering essence for 3 rounds.

What do you think Dev? These suggestions are mostly because Lunar Lunatism has absolutely no downside to using it, not even an FP cost or Essence cost for that matter.

The true power of the vampire is said to be linked to the moon, and anyone who has seen a vampire go all out can say for certain it has to come from somewhere. Can only be used while at 100 or more Essence. Upon using this skill, you enter a moonlight rage, curing yourself and becoming immune to Fear, Hesitation, and Charm. Furthermore, you gain the following effects:
* Damage you deal will also attempt to inflict Fear on the target.
* Enemies who attack you may be inflicted by Hesitation.
* Enemies facing you at the start of a new round have a chance to be inflicted with Charm.
* Recover 15% of your Scaled SAN as FP every round.

This effect and all inflicted status effects last for 3 rounds, and have LVs equal to your Scaled SAN.

There are many ways to go about this, however I feel that Spo's is a bit lackluster, all things considered. As of right now, it's overbearing because it doesn't drain Essence. Let's go in small moderations, for the time being.

The skill costs 6m to use, but it lasts until your essence is completely drained to 0.
The skill drains 25 Essence per round, whether it is day or night. However, if it is night, it uses full scaled sanctity, unlike during the day, where it will use half scaled sanctity.
Silvermists will use 33% of your essence and heals 3 per essence. However this effect is enhanced during night time to 2x, and during night-time it is 1.5x (Silvermists will drop your rounds on Lunar Lunatism quickly, after all).
You cannot use banquet during Lunar Lunatism.
After Lunar Lunatism ends, you cannot gather essence for 3 rounds.
If you drop a living creature to 0 HP during combat with Lunar Lunatism active, you gain Essence based off of their vit or yours, whichever is lower (MIN: 10)
