That should honestly be the rule for every mythic. Instant Shield Ally is not an acceptable Secret Skill for something at this level.
Most of the time they just slap on Instant [insert random move] and call it a day. A proper SS should strengthen the whole kit, not just exist to fill an empty slot.
I kept it at 49 so she would be useable with nyx, you have to keep something below 50 speed otherwise nyx is dead, even now nyx teams are suffering
as for why she doesnt have a single pirecing attack thats mind blowing on a slow monster.
we finally agree on something that ss should be unique move for all the mythics
To make here compatible to nyx 
Luna in s more than fine
Nyx basically got killed off the moment Calamitas was released. Her frontline just collapses to them, and Calamitas is still very popular even among high tier players.
monsters that can be HP boosted to give them mythic level stats with void piercing moves for the cost of 10 allowing you to fill the rest of your team with oppressive mythics and entrences?
Yeah it’s a nobrainer why they are still popular
This is the buff thread, not nerf thread.
100TU retribution is much better than 160TU vengeance on her. She’s got high attack so it one-shots almost everything and it’s her lowest TU attack. For 160TU she can kill two things with double faststrike.
Also, the SS is in order to effectively give her piercing for an attack / remove stealth for a double faststrike.
Luna is definitely completely fine as she is. The buff(s?) they gave her after release turned her into a nicely balanced sweeper.
Don rilla was really fine more tanky than luna and still got a buff so why not luna deserves it as well
What they should really do is make Secret Skills not count toward vulnerabilities. That way Luna with her SS would not be exposed to Antidote, and the same would apply to Bridalith and others.
Buffing bridalith? 
Antidote usually fails to kill her bulky ■■■ anyway.
You can keep the same tu as her retribution , she is a mythic without a piercing skill, don rilla was more tanky and have lower tu attacks and is faster and still got a buff
luna is extremely slow and for a slow sweeper without piercing thats mind blowing, ss should be something unique its extremely boring for these insta 1 tu move of basic attack, you would expect these type of secret skills to be on legendaries not mythics
She is not well given the current metagame she is very bad but not only her but more than 100 mythics are very bad and nobody uses them because in each act they concentrate on the meta mythics and one or another making everyone concentrate on making the same teams without having any variety in the teams the devs should release an update buffing everyone or if not the greatest amount of those mythics that nobody uses not making them broken or anything like that but making them visible so that they can be taken into account when making teams in order to have more variety and diversity
@Dev_VKC They could take this into consideration to make the game more attractive when making teams since from top 1 to top 20 they only copy and paste the same teams, so I think that giving a considerable improvement to all those mythical ones that nobody looks at would be a good way to make the game more fun and challenging.
Because Luna is really strong if u play her right try her after ghier with the right tanky mithics she will do her thing
I don’t own her , unlike the majority here I don’t talk based on the things I own
That’s not a flex. Most people don’t ask aggressively buffing or nerfing anything they have no experience playing with. Some monsters are easy to judge for a nerf like Pandora, Astra, Albion, or ALYCE or a buff for monsters like Onyxia, Marjorie, etc.. while monsters like Luna, Nyx, Cypridus requires experience to play them heavily with different teams and then judge.
You can also judge a buff or a nerf suggestion for how absurd they are too when they are too obvious.
Or you can agree/disagree on nerf/ buff idea based on the person who suggested it
Can Cythnia Quickdraw remove the other mark monsters restriction
Cynthia is one of those mythics that suffers alot because of speed, she is 50 speed that means she can not be used with nyx and is too slow for fast monsters and has no survival abilities.
Lol i didn’t realize i post that let me edit it
