Lucky Seven (Attacker)

Lucky Seven (Attacker) is a Keves Attacker in Xenoblade Chronicles 3. Upon using Unlimited Sword, becomes this class for 90 seconds if his ordinary class is an Attacker role. This class has a specific set of Master Arts, its s and Arts cannot be customised, and none of them are masterable themselves.
==Overview==
The class does not inherit any of the attributes of the class which Noah was before Unlimited Sword was used, nor any of the Master Arts or s equipped. It does start out as being due to Unlimited Sword granting this , but only for 10 seconds by default. However, the buff is applied before Noah's class is changed, allowing skills such as Strengthening Gambit to increase the duration before they are replaced.
There are two main uses of this class. Unsurprisingly, both are designed for damage. They are split between whether or not the enemy is vulnerable to .
===Enemies vulnerable to Doom===
In fights against any enemy that is not a , boss, or part of , this class reduces combat to the point of triviality with the Cut In Half. Every hit has a roughly 6% chance of killing enemies instantly - unless one is extremely unlucky or extremely inefficient, this can be expected to happen mere seconds into a fight. This is obviously handy for ploughing through mob encounters.
It also shines in grinding out CP by killing Elite monsters, who are generally vulnerable to Doom. Elite monsters provide more CP than other enemies, especially if they are far above the party's ; spamming and hoping for a lucky Doom proc is one of if not the most efficient means of grinding CP. This is aided by Unlimited Sword granting , reducing the risk of being killed.
===Enemies invulnerable to Doom===
Enemies which are not vulnerable to Doom are not quite as trivial to deal with. Nevertheless, this class is well-equipped to handle them with a plethora of offensive capabilities. The centrepiece is , an Art which inflicts the entire combo in one go against all targets in range, while bypassing resistance. Using this class largely boils down to charging Final Lucky Seven by repeatedly using , then using Final Lucky Seven on all enemies. This works especially well when combined with a Chain Ring or Shackle Ring, due to the art's special synergy with these accessories.
Final Lucky Seven aside, the class enjoys , a Smash which can be used in s. It also has another strong Chain Attack art pair in / (or the almost-as-strong / before Harmonic Wave is learnt). Its stat spread is excellent, and it has almost-objectively the best in the game. Opening Stand and Realm of the Master are both excellent s, giving a very high rate and spammable Arts to go with it.
It also has utility in that when Noah enters Ouroboros form when in this class, Origin Blade is made available immediately. Reduce All can therefore be inflicted easily and frequently when in this class.
The main drawback of this strategy is its lack of customisability, as the class cannot use Master Arts or Master Skills from other classes. This limits its damage potential against single targets in postgame optimisation. Furthermore, while it is not the squishiest class due to 's high rate, it is also not the tankiest. It is difficult to prevent it from taking , because Smash's aggro generation cannot be reduced. The invincibility granted on startup does mitigate this - potentially entirely, with deliberate setup (see below).
===General strategy===
Ten seconds of invincibility is not a lot, especially when a lot of that time is lost on the class's slow Art animations. It is, however, possible to extend this far beyond what skills can accomplish: if a party member other than Noah has (preferably in conjunction with Capable Hands), Pause Buff Timer can be used to extend the invincibility. If Glittering Melody can be used frequently enough, this can be done indefinitely. Furthermore, Invincible can be spread to by Interlinking; if she has , it can then be spread to the entire party. Keeping the buff timer paused with Glittering Melody allows the party to be invincible indefinitely, leaving them vulnerable only to enemy attacks which remove buffs. This is valuable both for non-Doom strategies and for CP grinding with Doom, although sharing the invincibility with the party is overkill for the latter case. However, it does not work in Challenge Battle Mode on Hard , where party invincibility is disabled.
The class also suffers from Unlimited Sword's main weakness: an extremely long cooldown. This can almost entirely be mitigated with Capable Hands. Lucky Seven (Attacker) is compatible with having Flash Fencer as Noah's base class if Capable Hands has not yet been mastered at rank 15. It does lack a front positional Art, which can be a deadly drawback against certain bosses whose sides or back cannot be reached - enough of a drawback that Lucky Seven (Healer) may be a better alternative. On the other hand, if Capable Hands has been mastered, Seraph is often a good choice for a base class, due to the ease with which it builds up Talent Arts and gains .
