@bio0pp: Thank you so much, ill follow the advice good luck being the first 250 Mihile! ^^

Hyper stats are correct. Inner ability is a bit subjective as he mentioned. 30% crit is the line you're aiming for. Although I have been considering rerolling my IA after I hit 250 and replacing it with boss %, since it is possible to hit 100% crit while bossing with maxed crit hyper stat, crit mag soul and 210 phantom link. Buff duration is a possibility but imo its complete trash. The more stacks you have from blocking with royal guards the harder it is to land the next block and the royal guard damage is pathetic since it is limited by damage cap. I prefer to let my stacks drop so that I have the option to clutch guard if needed. My stance on this may change though in the next big patch since royal guard buff is being changed a bit and eventually in 5th job damage cap will be removed. We will lose the ability to tank 1 hit skills, unless we have the royal guard buff on and the iframes after guarding will be extended from 2 seconds to 4 seconds.

@bio0pp: Oh thanks for stopping by do you have any other ideas when it comes to hyper stats and inner ability? Or is okaythen's response a good to go standard? Im now 182 and at around 250k with the cd buffs, ive started a kanna to help farm in BG to start cubing so, i want to know what to aim for to get the best results (Sorry im barraging you, theres not much activity in basil lately and Mihiles in basil are all but extinct =/ )

Mihile is not a 'bad' pick by any regard, for reboot especially. With heroes patch the class received a ton of final damage % and an additional 2 lines on their main attacking skill which sky rocketed their damage. They are at the bottom of the DPM charts because their final damage isn't factored in, and they are able to deal exceptional damage with limited funds. The main reason you wouldn't make a Mihile in reboot is the fact that Haku gives an insane party wide magic attack % buff that allows mages to blow everything else out of the water in terms of end game bossing.
TLDR: Mages are king in reboot, comparatively everything else is trash in party play.

@piana: Mihile also has magic crash, although it is moot because most new bosses dont cancel wa/ma(unless you mean DR). Almost all top tier dmg dealing classes have a bind and since most new end game bosses resist bind for a certain period of time afterward thats also moot. Bishop works in synergy with Mihile, but the ability to make an upwards of 60 attacks useless on up to 6 party mems on bosses like Damien,lotus, and Lucid increases your parties dps by a great margin considering for that duration they dont have to worry about anything but hitting their target instead of dodging an onslaught of skills. You cant compare one bind and one revive to the amount of lives youll save with essentially invincibility for your whole party.

@okaythen: Thank you so much! And yes i know 50% dmg would be broken, i was speculating it would only apply to one line of their dmg but this makes far more sense, wish theyd make it clear in the skill description =/. Im also having a blast with the class so i dont plan on switching, their bossing playstyle is very rewarding when you land a Royal Guard.

@piana: Although palidin is definitely the superior option atm, it also plays like a tanky hero during bossing while as mihile with royal guard can mix things up. Yes i said atm because with the introduction to 5th job i believe Mihiles will be by far the best supporting warriors a party can get and will be extremely useful thanks to Rho Aias.

Thanks again for the responses, ill leave the post open just in case any others want to add to any other points ^^

@okaythen came in clutch

idk how fun the mihile class itself is, but it'd be fun being being maybe one of three active mihiles on reboot.

Hyper stat is like any other class;
Damage, boss damage, pdr and crit.

Inner abilities you should be aiming for are critical rate and boss damage. Mainly crit.
Attack speed is useless since mihile already reaches soft cap with its own skills.
Buff duration can be useful for royal guard, but crit and boss are better.

As for soul link, through my experiences with it, you will always have the effects when it's toggled on even if your party members aren't in the same map as you (so it's a free range boost just to have members in your party) but they have to be online. Offline members don't count.
Your party members need to be near you to get their effects. So if they don't have the visual effect, it means they aren't close enough. The only party benefit I got from soul link was tanking the damage they take, so it's easier on them.

The percentage applies to the attack of royal guard.
So 1 stack of it gives a 10 attack boost, meaning your party members with the effect will get 50% of it which is 5 attack.
5 stacks would give 50% of 35 attack.
If the skill gave your party a 50% damage boost, that'd be broken.

Just a side note, mihile is a bad pick especially in reboot. Stick with the class if you enjoy it, but if you aren't having a blast with it, I'd suggest you pick a stronger or a more supportive class if you're the party kind of guy.

Wait, I know there's some people that main Mihile. Soon you'll get your answers.

I don't mean to discourage you, but you probably picked the most uncommon class to play. May have to figure some of this out on your own.
