Yellow hunt is a great secondary choice for advanced players. With yellow crafting materials, you can craft Revenge, Injury, and Penetration gear sets.
Revenge set is similar to Speed set. It is slower at the start of battle, but becomes faster than Speed set when your HP is low.
Injury set is very niche and not broadly useful, but is a great counter against healers and HP scaling knights and brawlers.
Penetration set is usually the best two-piece set for any single target attackers.
Yellow hunt is not recommended for beginners as its unit restrictions are a bit fussy, but can be worth farming if you've done your fair share of Red and Blue hunting.
The Colossus Mech is immune to CC, Poison, SPD Down, and Reduce Action Gauge.
The Mech comes with two minions. When they attack, the mech will trigger flanking and attack together.
The Mech's attacks will penetrate DEF and apply Injury to units (3% of max HP per attack).
Attacks that deal damage in proportion to enemy HP are only half as effective against the Mech.
If the Mech has more than 4 debuffs at once, it will self-cleanse, and buff itself.
Every 4 turns, the Mech will dispel all buffs from your units, and apply SPD down and Restrict.
♦️ When a unit attacks the Mech, they will receive 1 stack of Danger Level (up to 5).
♦️ Danger Level cannot be cleansed or reduced. The ONLY way to clean Danger Level is to cast a non-attacking skill.
♦️ The Mech's attacks will deal additional scaling damage based on Danger Level.
♦️ Enemies will target the unit with highest Danger Level first.
The most important part of Yellow Hunt is managing Danger Level.
DPS units who can't take much abuse MUST have a non-attacking skill to reset their Danger Level.
Healers, by nature, will always have very low Danger Level.
A high-hp tank with no non-attacks can be used as "bait" to draw aggro. Beware that this kills them very quickly after Danger Level 5 due to scaling damage.
Erica: S2 is a non-attack.
She is a counter fighter, so if she counters too often, she might accumulate too much Danger Level before she can S2 again.
Chaldea (Neno): S2 is a non-attack.
She is a counter fighter, so if she counters too often, she might accumulate too much Danger Level before she can S2 again.
Berrica: S3 is a non-attack. DEF down and respectable damage, dual purpose with Red Hunt.
Heidi: S2 is a non-attack. Very high damage.
Bunny Girl Erica: S2 is a non-attack.
Bonnie: S3 is a non-attack. Dual purpose with Red Hunt.
Hinorie: S3 is a non-attack. She will only use S3 when low on health, so she will manage Danger Level better than most.
Aoi Hinamori: "Be Happy, Okay?" is a non-attack and has a 35% chance to cast per every basic attack (S1).
Aoi WILL DIE if she never uses the non-attack during auto battle, which is rare but possible.
Her Curse will indirectly kill one of the minions if you attack the Mech with single-target damage.
Radiant Vow Rubi: Passive is a non-attack. Be careful that the passive doesn't activate when her own HP gets low.
Make sure that someone else draws high aggro so Rubi can use her passive, otherwise she will die.
Dual purpose with Red Hunt.
Galornia: S2, S3 are non-attacks. Dual purpose with Red Hunt.
Preema (+Noclyn): Classic NocPrem also works here. Solid foundation to build the rest of the team on top of.
Basically all healers will self-manage their Danger Level. You can bring anyone you have, there isn't much difference for this hunt. Debuff cleansers can be useful for cleaning SPD Down and Restrict but cannot clean Danger Level or Injury accumulation.
Very high HP units with no non-attacks will slowly but surely accumulate Danger Level 5. This can be used to draw full aggro from the enemies and away from your other units.
Not all teams require an Aggro Tank. Normally, bringing more DPS to finish the hunt quicker is more desirable.
Be aware that no matter how tanky your tank is, they will die very quickly once they reach Danger Level 5. If they have high SPD, they'll reach the Danger Level quicker, and die quicker.
