Lunar Charms are often not made with an evident purpose in mind like ability Charms but can be put to any use the Lunar can think of.
Stamina Charm- the Lunar can change their body temperature
Dexterity Charm- they can repeat one physical ection that they failed.
Fault Mastering Swiftness
Solar Ability Charms are more evidently designed for a purpose. Iron Whirlwind Attack dramatically increases the number of attacks the character can make with a melee weapon. Lunar Charms are more like effects that don't have a purpose in themselves but can be put to any use they can think of.
Higher Essence Charm they can replay the moment using a different method without incurring penalties for repeated action. This Charm is good but it's basically the Third Attribute Excellency (a Lunar secret weapon because it does the same thing the Third Ability Excellency does only is more versatile.) It would be good to make it more distinct.
Stamina Charm At Higher Level they can freeze of boil water within their proximity.
