Let's talk about a Hunter only build, the Adverse Spirit Rage build.
In this build, we aim to take advantage of the two following effects:
'''Daredevil''' (Hu Lv45): Increases your damage by 7% if your HP is below 35%.
'''[[Status effects#Rage|HP affect Power (Rage)]]''': A weapon effect that increases your damage dealt the lower your HP is. The higher level the weapon effect is, the higher your damage ceiling and damage scaling.
Porting the Rage Level table:
Using these two effects, even if you stay at the 35% HP threshold, and using a Rage Lv3 weapon, your damage dealt would be increased by 1+ (1-0.35) * 0.32 * 1.07 = 1.22x, or 22%. Using a Rage lv4 weapon, your damage dealt would be increased by 1+ (1-0.35) * 0.45 * 1.07 = 1.31x, or 31%.
<u>'''Important tidbit:''' AI behaviour means that they are always prioritized to heal the player if they drop below 35% HP. It's also impossible to bring an NPC without access to Resta. '''As a result, to run this build, the player is not allowed to bring any NPC partners.'''</u>
Of course, staying at such a low amount of HP is very dangerous. Thankfully, there are several abilities that can help us out.
'''Adverse Spirit''' (Hu Lv7): Increases your DEF and MND by 75% if your HP is below 35%.
'''Damage Resist''' (Va Lv2): Reduces all damage taken by 10%.
'''Photon Barrier''' (Fo Lv7): Negate damage below 3% of the player's max HP.
If the player is adequately rebirthed (for HP, DEF, MND, and ATK), and utilizing the 20% damage reduction from [[Damage#Damage Taken|matching shield-weave attributes]], it's possible for the player to coast through even Infinity Rank Missions with little to no damage taken.
Since our defenses are so stacked, it can be surprisingly difficult to let the enemies hit you until you are below 35% HP. Therefore, instead of standing around for a minute, we are going to utilize [[Status effects#Reflect|Reflect]] weapons.
Weapons with reflect deals damage to the player based on the amount of damage dealt. Porting the table again:
In other words, Reflect Lv1 Weapons are the fastest, while Reflect Lv5 Weapons are the most controlled.
Note that weapon stats still affect your damage, it's entirely possible for you to take less damage from Reflect even if you are using a weapon with higher level Reflect, if the weapon has low stats.
Note that you cannot use Ranged Weapons for either Rage or Reflect purposes, as Ranged Weapon effects do not apply to their Charge Shots. As a result, both their Rage damage boost and Reflect damage dealing are both quite ineffective for this build.
As for Technics, the only Technic with Rage is [[Nosmegid]], which is far from an effective technic to run.
Comes with Reflect Lv1, making it the most efficient weapon to self-damage.
Comes with Reflect Lv3, and upgrades to Reflect Lv5 after unsealing, which allows the player a varying degree of control over their HP.
Twin Claws with Rage Lv3 and 120% PA Rate, enough said.
It's one of the weapons with the highest Rage special level, which means it benefits a ton from the [[Adverse Spirit]] build.
[[Double Cannon]], [[Twin Cannon]], [[Lavis Blades]], [[Lavis Cannon]], [[Lavis Dagger]]
Has Rage Lv3 and 130% PA Rate, making it benefit a ton from the Adverse Spirit build.
They are all dark-locked though, so they are less versatile than [[Daylight Scar]].
Using a basic handgun's Charge Shot II without Full Charge Shot provides the lowest recovery in the game, and doesn't need you to give up your Lv30 Resta disc. This allows us to restore some HP without going out of the 35% HP threshold to trigger Daredevil and Adverse Spirit.
