Assessment

This section contains subjective remarks about this class. Relevancy of information and recommended weapons can quickly change over time. Use substantial discretion before heavily investing resources.

Relic Buster is effectively a spin on the Extra Class Mechanic mixed with Glorybringer, albeit streamlined, able to wield sabres and guns, and with the advantages of more open skill selection not found on Extra Classes.

In particular,  Limit BurstAll allies gain Charge Bar +Instantly boosts Charge Bar by

(Consumes all Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)

(Boost to ShieldNext ATK received will be ineffective for a fixed amount

s.

It's resource buff, Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
, is also more simplified and more resembles those of characters with similar mechanics, though unlike many of them, the class neither starts the battle with any nor has support skills to restore them automatically over time. Outside of the Class Champion weapon effects, the class is completely reliant on  Engage AugmentsGain 5 Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
(Max: 5) and restore HP (Healing cap: 2000).
(When HP is 50% or above: Also gain StrengthATK is greatly boosted based on how high HP is
Strength: 45%-15%Duration: 3 turns.)
At level 30:
(When HP is below 50%: Also gain JammedATK is greatly boosted based on how low HP is
Strength: 30%-90%Duration: 3 turns.) to cover resource needs.

Most of the other possible effects available to Mechanic can be covered by subskills, but Relic Buster notably lacks the capacity to deal plain damage. The same cannot be said for the sheer variety of Glorybringer options, but a sabre-wielding Relic Buster can certainly dish out comparable basic damage without needing specific subskills or weapon grids.

In addition, being able to wield sabres in addition to guns provides the class even more versatility, fitting nicely with Ultima Sword teams. Each weapon type also provides different benefits to regular attacks, somewhat emulating a Power Frame Companion.

In longer and more difficult battles, the defensive penalties can prove a liability however, with more frequent attacks draining Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
s or dealing more damage. The Master Level upgrades do help offset this, but the class might still be dependent on a character capable of drawing attacks away or otherwise shield it from harm.

Notable Main Weapons

Relic Buster can work well with almost any gun or sword. If using the class for OTK purposes, main weapons that contributes to this goal (for example, charge attack effects like bonus damage, inflicting DEF DownDEF is lowered
debuffs, granting Charge Bar +Instantly boosts Charge Bar by
, etc.) should be considered.

Certain swords with effects that activate on triple attacks can work well with Relic Buster, as the MC will always triple attack so long as Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
s are present. Guns that provide increases to skill specs when wielded as a main weapon (either passively or through charge attack effects) will help boost the automatic damage when Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
s are present.

  • Hraesvelgr🛑This weapon requires many Gold Moons to acquire, and may also require the use of several Damascus Ingots to uncap to its full potential. Think very carefully before making the heavy commitment to acquiring this weapon! - This weapon comes with sharp multiattack restrictions to compensate for its strong supplemental damage, damage cap boost, amplify, and split-strike effects. A Relic Buster MC can work around these restrictions with the use of  Engage AugmentsGain 5 Machine CellConsumed upon normal attacks and using skills (Can't be removed / Max: 5)
    (Max: 5) and restore HP (Healing cap: 2000).
