General Strategy
Vicarious Clara is a Summoning skill (from the Necromancer job) which creates a 3 layer wall that blocks incoming damage. It is vital to defeating these bosses. It can be recast multiple times to stack more layers. Status effects, including instant deaths, still go through. Viable alternatives are Group Defense (Legion race) and Electromagnetic Armor (Makina Master job). These don't require HP to cast, but they only have 2 layers.

Basic strategy is to use Clara to block attacks and use applicable skills to inflict statuses and deal damage.

General Strategy
Holy Martyr (Pope) and Endure (Power Fighter) are good abilities to have on every party member.

Carbuncle (Summoner) is useful to reflect some spells; Spiritualist job grants the 'Skill Use: Summoning' ability.

Time magic (Slow, Stop) is effective on most bosses.

Dispel (White Magic) (Priest) can be used to clear the bosses' buffs.

For dealing significant damage, you generally want to stack buffs, debuff enemy defenses, or use attacks that ignore defenses. Other ways to increase damage Clear status effects with Saints' Recovery (Holy skill) (Paladin) or other skill. If you are having trouble at the start of a fight (eg. can't set up Clara), try having 3 members cast Clara and 1 member (preferably the fastest one) cast a heal (eg. Hustle Dance). Your party should be able to tank a hit with 'Endure', so most of your team will be able to summon Clara. Mana Drain attacks (Evil Mist ability) can quickly neutralize most bosses. This strategy is not really necessary normally, but becomes more useful at higher labyrinth levels, where the bosses have higher HP (but still 9999 MP).
 * Some enemies have physical resist, which is separate from defense.
 * Geyser (Special) (Adventurer) and Necrosis (Dark) (Minor Chaos) ignore defenses and are certain hit.
 * Palace Knight learns single attribute debuffs, Snake Miko race learns Weakening Dance which debuffs all attributes.
 * (Stacking buffs) eg. Transform (Hero of Justice), Inner Focused Mind (Magus Fist), Focused Spirit (Swordmaster/Power Fighter), Daisy Bell (Vocaloid), Song of Offense (Minstrel)
 * The relevant slayer ability can substantially boost damage for skills with normal attack effects (effect: +).
 * 'Element Strike' from abilities/weapons, with relevant boosters, lead to more damage for skills with normal attack effects.
 * Accuracy issues can be resolved with Bullseye Song (Sea Palace Maiko).
 * Antibiotic Injection (Medicine) (Doctor) provides immunity to status effects for one ally.
 * Anti-Death Song (Kitsune Geisha) provides immunity to instant death, expel and climax for all allies.
 * 'Electromagnetic armor' (Makina) (Makina Master) and 'Group defense' (Insect skill) (Legion) can be used as alternatives.
 * This strategy will not be effective against physical reflect/nullification.
 * See above: 'for dealing significant damage' (debuff enemy willpower for mana drain attack)
 * Inflicting silence is more effective (seals more skills) than mana drain, if the enemy is vulnerable.
 * Mitsuko (Honey Pot) is highly recommended for this strategy, since she has access to Slime, Scylla and Ghost races.
 * The following setup works on all bosses (except for physical nullification) at all labyrinth floors with no weapons + no slayer:
 * slime division -> high tentacle up + transform -> focused mind + inner focused mind -> focused spirit + power charge -> mana drain attack (+ bullseye song, encouraging dance)
 * (note: inflicting stop or other status effect can aid setup)
 * Shorter mana drain setups can be viable in a number of cases (assuming use of relevant slayer ability):
 * At labyrinth floor 100
 * Using strong equipment
 * Against a boss vulnerable to debuffs
 * Using the abilities Unyielding Fighting Spirit / Strength in Solitude (Hero of Justice)
 * eg. slime division -> power charge + focused spirit -> high tentacle up + mana drain attack (+ race slayer, daisy bell, encouraging dance)
 * [Easy Mode] Crisis Hairpin - although the description states 'When falling below 20% HP, increases Magic Evasion by 75%', it actually grants auto Daystar instead...
 * It can be found in random labyrinth chests, through Black Market Delivery skill, or received as an affection gift from Miyabi (Cursed Doll).

The Bosses
Their HP and attributes increases based on labyrinth floor (not affected by difficulty).

All bosses can clear your teams buffs, including deflectors such as Clara. This will generally (but not always) cost MP.

Many of the skills used by the bosses cannot be dodged or reflected (classified as 'certain hit'). Holy and Dark skills are usually in this category. Physical skills can be dodged, magical skills can be dodged and reflected.

My opinion of the relative difficulty of the bosses (same bracket = similar difficulty):

Rewards
You will need Lockpick II (or relevant accessory) to open the green chest behind the boss.


 * i.e. Demon Arts, Ocean, Slime, Beast, Snake, Tentacle, Wing, Insect, Plant, Corpse, Artificial, Nature, Breath skills

Other/Unsorted notes
If a party member dies with a deflector such as Vicarious Clara (eg. through Instant Death or other status effect), the deflector will persist when the party member is revived.

On stacking buffs Mana drain long setup Mysterious dance and Madrain (Black Magic) deal low MP damage, but ignore defenses.
 * There are a number of skills which provide a generic stat buff (indicated by +atk/def/agi etc in the status bar during battle), however, these do not stack. For example, using Song of Offense, Encouraging Dance and Enhance Attack will only result in one +50% attack buff.
 * Some other buffs are considered separate - you can observe they are represented by a different icon. They stack if both icons appear in the status bar. Many self-buffs fall into this category.
 * The attack abilities Unyielding Fighting Spirit (at critical HP, +50% stats) and Strength in Solitude (+25% stats for each defeated party member) can be used to dramatically increase stats on top of active buffs.
 * Spellblade Fire -> Slime Division -> Slime Division + Transform -> High Tentacle Up + Four Spirits Fist -> Focused Mind + Inner Focused Mind -> Focused Spirit + Power Charge -> mana drain attack (+ race slayer, Quick, Sky Dance, Daisy Bell, Encouraging Dance, Draining Light Talisman, Lucky Star) (+ Slimed, Horny, Pleasure Strike) (+ Unyielding Fighting Spirit, Strength in Solitude)
 * (note: if Lucky Star hits enemy, it can be removed with Dispel)
 * (note2: Focused Mind / Inner Focused Mind also boost agility)

On weapons
 * Using skills while using a matching weapon type will increase damage (eg. Swords with Sword skills)
 * {Spear / Fan / Dance / Song / Service} skills grant small initiative bonus on cast {200 / 500 / 800 / 800 / 800}
 * {Club / Flail} skills ignore half of enemy defense
 * {Axe} skills ignore all of enemy defense
