- The Enforcer Class, specifically: the Psycorruptor and Mastermind. Their stats and weapons may be lackluster compared to the other job classes, but the advanced Arts and support skills they learn more than make up for it.
- Want a dedicated group healer? Learn Irina's 'Smooth Recovery' art, or Astral Horizon + Astral Heal, and you'll rarely need to bother with Soul Voice challenges again, except for building affinity.
- Brainjack + Servant Sacrifice enables you to insta-kill virtually any non-boss/non-tyrant enemy and receive up to 50% HP/TP at the same time. Which can be supplemented by the 'King's Decree' support skill. Even if Servant Sacrifice misses, the enemy is still rendered imobile until Brainjack wears off.
- And at Max lvl.5, Black Bane damage scales for an additional 300% per debuff the victim has. Five or more debuffs is enough for Black Bane to to lop off anywhere from ½ to nearly 2/3 of the target's HP in one hit. And since it's an ether Art, you can further increase its power with Ether Attack Plus XX augments.
- Three TP Gain XX augments. When you use an art, your TP will increase by 200+ for each gem you have equipped. With three of these equipped, even arts where you'd normally lose TP will have you gain more than you use. With these gems, you'll be able to spam Overdrives and arts that normally have lengthy cool downs to them for days and become a Nigh Invulnerable Apocalyptic force of destruction.
- The Ether Blossom Dance build takes the above and puts it into Overdrive. Ether Blossom Dance is a build that combines the dual gunner class with the basic swordsman class to create a Nigh Invulnerable Lightning Bruiser that would make Dunban proud. Blossom Dance is a weapon-damage art (used with an Ether-based weapon) that deals more damage in a melee combo and bypasses any elemental resistances, and the dual gunner class has access to arts that buff Ether and TP, as well as the game breaking in its own right Ghostwalker, which grants decoy, which makes every attack that hits you miss for a short while. If you're going up against anything that reflects ether, just slap on a Nullify Ether Reflect XX augment for them. By using this with the three TP Gain XX above to overdrive spam, this set is capable of taking out enemies only thought possible to beat with a Skell, and is even better than Skells in that regard!
- The Ether Blossom build has been outdone with a combination of Potential XX + Ghostwalker abuse, using the dual gun setup (skip to the last two minutes).
- Too early to do Ether Blossom builds? Last Stand Ramjet Rifle is there for you. The Ramjet Rifle is a normally terrible assault rifle with horrid stats, but the incredibly redeeming quality of giving you 300 TP per shot (with 3 shots). Last Stand is the last skill in the Duelist class, a pretty mediocre class otherwise. Once at level 5, Last Stand takes 1000 of your TP to grant everyone else 2000 TP. Combine the two, and you're giving every other party member a constant flow of TP for their skills while building up your own TP rapidly until launching Overdrive to (you guessed it) spam the Ramjet Rifle and Last Stand even more. The main drawback with this build is completely destroying your ranged damage... which doesn't matter THAT much if you're playing support/have good melee arts. Have fun.
- The Skells. There's a very good reason why the game holds off for so long on giving you one, as once you do have one, you have very little reason to ever leave it again outside of situations where you flat-out can't take it with you. Any enemies that weren't designed with Skells in mind become complete Curb Stomp Battles for your team, which a shocking amount of the story bosses weren't. Even the basic model you start out with can curb stomp any small enemy with ease that isn't level 40+ or so, and even take on level thirty or so bigger enemies rather easily with a well-leveled party for support. The fuel that supposed to balance them almost never runs out unless you go out of your way for it, and it's easy to refuel them at the base since the miranium needed isn't a lot. And outside of battle, their mobility and speed are a godsend in navigating the huge world, and once the flight ability is unlocked, there's nothing holding you down.
- In addition, there's a weapon level thirty plus Skells can equip called the G-Buster. It's pricey but well worth it to purchase. Why? Because, against most normal enemies, this thing can usually knock off half to near half of their health when used, as well as deal a large chunk of damage against most bosses. If that's not enough, it often inflicts Stagger, which, for larger enemies, opens up a nice window to bind them and make them vulnerable to other attacks. Give each Skell one of these babies and watch as your team tears through the enemies HP. The Verus Skell frame also comes with a level thirty version of it which still has no problems taking off large chunks of health off of enemies HP. The only real drawback it has is having a very long cool down and fuel consumption and even then it doesn't matter too much when it can be used to make battles against normal enemies take almost no time at all and the skells having a mechanic which makes all arts usable again despite how much cool down time was left, as well as the generous amounts of Miranium one can acquire in the game and the ability to refuel when binding a giant (which is often the result of a G-Buster attack).
- The G2 variant is slightly weaker, but far more effective because it's the game's only mid-ranged melee weapon and it's the only melee weapon that has AoE. In addition, it hits all enemies within its range twice, giving it a much higher chance to inflict stagger and criticals at the same time.
- An alternative option is the M-Sniper. The Mastema Skell starts off with it, and there will be little need to replace it (except with the G-Buster above). It deals a good amount of damage in its own right, and is more capable of inflicting topple on enemies.
- The Meredith M-Missiles are absolutely devastating against appendages; they target all the appendages on a target, even the ones that a Skell can't normally target. Combined with a ton of appendage crushing augments, and it's easy to see why they're essential for grinding tickets off the Global Nemesis. In addition, every enemy appendage broken by a Skell grants a not-insignificant amount of fuel, meaning you'll never have to buy fuel with miranium again.
- The Phoenix Wings are the go-to weapon when it comes to destroying multiple targets. Push the button and watch nearby enemies get launched away, if not killed outright!
- The Lailah line of Skells is rather famous for its Nigh-Invulnerability. Its Overdrive increases its defense to sky-high levels, allows it to regen health while in Overdrive, makes it immune to debuffs, and doesn't use any fuel while in Overdrive. Give it a lot of weapons to increase TP quickly and a few attribute resist augments, and you have a Skell that'll never die. Another bonus is the line also has crazy high accuracy on its weapons, so even if an enemy puts up an evasion spike, it'll still be able to hit them with little problem. It's so crazy that it's been proven that even the level 30 version is capable of soloing Telethia, the Endbringer.
- Meanwhile, the Mastema line is blessed with excellent ranged attack, and there's a physical-attribute ranged superweapon called the EM Zenith Cannon that ignores enemy resistances. Level 60 versions of both, combined with as much ranged and physical-boosting equipment as possible, result in a machine that can even punch through ultrafauna in only two or three hits. The aforementioned M-Missiles - which also run off the Mastema's superior ranged stats - can be added to make the cannon's extreme fuel consumption a complete non-issue.
- Last Stand allows you to feed your party 2,000 TP apiece. During secondary and tertiary cooldown, it can be used back-to-back. Having two or more active party members with Last Stand sets up a feedback loop that easily allows you to maintain TP for reviving teammates and Overdrive indefinitely.
- One can also use the Ramjet Rifle in conjunction with 'Last Stand', as the Ramjet's auto attack is more than enough to fill up TP for both it and Overdrive.
- Astral Protection is an aura available by using Psycho Launchers, that boost your resistances. With the proper armor and augment set-up, you will survive any of the Bonus Bosses' attacks, with barely any necessary healing.
- The height and distance afforded by the game's sprint jump physics allows you to reach areas that're meant to be accessible only by flight; effectively allowing you to reach late game areas early. Once you get the hang of it, you'll find yourself trying it everywhere just to see what out of the way bluffs (and treasures) you can reach next.
- Afterburner is extremely deadly when used with Overdrive. Charged up to the maximum limit, it can go beyond decimating even the largest enemies with ease, and it can affect multiple enemies in the attack's range.
- Naturally, the game's Infinity +1 Sword, the Antimatter-R Skell Superweapon. Against the toughest Tyrants, it will take off a quarter of their health at the very least, and outright slaughter anything else (in the general area). Best of all, it only takes up the two back slots, leaving you with space for some normal weapons (like those Merideth missiles) for lesser foes or parts grinding.
- Core Crusher is a skill that makes any ether-based attack deal more damage, at the cost of not being able to break appendages. Core Crusher, unlike other skills, is an independent multiplier that multiplies overall damage instead of being addititive like the similar Ether Boost, which is affected by overall modifiers. No other attribute has such a bonus. If that wasn't enough, there's the Appendage Crusher augment, which increases damage dealt to appendages. This gives ether such a massive advantage that nearly any weapon that isn't ether-based might as well not exist.
- The Diskbombs take advantage of a glitch to turn them into handheld weapons of mass destruction. These sidearms fire three little projectiles in each volley. One potential built-in augment for salvaged Diskbombs is Custom.MSL-MAG, an augment that increases the number of shots missile-based weapons fire at the cost of reducing their damage. On Diskbombs, the bonus is applied to each individual missile. So with a rank I Custom.MSL-MAG, instead of firing four bombs in a single auto-attack, the weapon fires six. With a rank IX or X augment? Macross Missile Massacre doesn't even begin to describe it. But it doesn't end there. If you equip another Diskbomb in the right sidearm slot and the modded Diskbomb in the left (not vice-versa, as the boost will not apply but the penalty will)... the right Diskbomb inherits the boost, without the damage penalty. The end result is a pair of sidearms that can outdamage most Skell wepaons and build up GP with ease.
