Explanation

• Hellbound: Fire will apply 5 stacks of Spirit Chains of Suppression to you.
• If you fail to kill the adds by the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Mithras will do one too, if he isn't dead by his third turn.
• Mithras will follow up with Covenant Bless Underside whenever he, his allies, or you use a Fire/ Light attack. The hit doesnt hurt, but it does heal Mithras and his party, which can prolong the fight. Cybele and the Shiki-Ouji on the right also have healing spells.

Illuyanka (Underside) effect overview

• Self gets 50% HP, 180% Ice damage, 20% accuracy, 3 MP discount for Ice skills, and immunity to Spirit Chains of Suppression.
• The team gets 80% Ice damage and 50% accuracy.
• If any team member uses an Ice skill, Illuyanka casts an Ice AoE on all enemies (up to 4 times per turn).

Colors

• Clear for the fusibles ruleset, and for Bufudyne.
• Purple for Magic Amp II can slightly improve DPS. However, this is only recommended if you have him use Ice Age or Ice Age (Underside).

Skill Transfer

• Ice Age (Underside) is ideal regardless of color.
• If Ice Age Underside is unavailable:
  • Clear should transfer a damage booster, such as Ice Amp or Ice Boost.
  • Purple should transfer regular Ice Age. If you don't have it, you should run Clear instead.

Brands

• MATK% Spell.
• Due to his MP discount, Divine's MP regen is probably not necessary.

Jack Frost (Underside) effect overview

• Self gets 15% Ice/Light damage, and Concentrate (2.25x damage) on his first action - together, these are 87% damage on average across his 2 actions on the first turn. Also gets 50% HP and immunity to Spirit Chains of Suppression.
• If an ally uses an Ice/Light skill, Jack Frost automatically casts ATK Buff (up to 3 times per turn).

Colors

• Clear for the fusibles ruleset. It also gives Hama, which can be useful in the Light area of HPU.
• Red for Bufula, as it's stronger than his innate Bufu.

Skill Transfer

• May need Resist Fire if you can't win in one turn, to ensure Mithras doesn't get extra turns off him.
• Jack Frost does not have any MP discounts, so 7 MP skills such as Ice Age may be too expensive to cast repeatedly.
  • Ice Age (Underside) starts at 7 MP, then becomes 6 MP at max level. This is the best skill he can use, but the cost of maxing it is very high.
• Clear can level up Bufu and transfer a damage booster, but transferring level 1 Bufudyne will do more damage.
• Red should level up Bufula and transfer a damage booster, such as Ice Amp, Merciless Blow, or Ice Boost. This will outdamage a transferred Bufudyne.
• Bufu, Bufula, Mabufu, and Hama can all be leveled cheaply - run Chapter 1 Leveling Quest for Slimes to feed him for skill points, then transfer skill dupes from 1★-3★ to level his skills.

Brands

• MATK% Spell or Divine.

Misc notes

• If using Ice Age (Underside), then Concentrate only affects the initial hit, not the AoE chain.
• Consider transcending him for skill switches, as that lets him easily swap builds between multiple areas.

Team notes:

• Anahita: 204 magic, has Ice Accele, Purple has Ice Amp, p1 has 15% damage, p3 has 20%. 30% magic damage (plus 15% all-damage if p2) and +1 MP recovery aura for party while Bulwarked (which she also provides, but only once due to Suppression). Hell Stream (280 power single-target, casts ATK/DEF Buffs and ATK/DEF Debuffs). If p3, also gives the party 1 count of Fortify.
  • Also note that the boss does not have Bulwark pierce. This is good defensively, but also means he might break your Bulwarks with damage before they would wear off naturally.
• Atropos: 192 magic, 5% damage, has Merciless Blow, p3 has 20% damage. Severed Fate (160 power single-target). Purple has Infinite Chakra, so she should run Spell brands.
• Norn: 193 magic (213 with maxed Moment of Fate), has Merciless Blow. Automatic cast of Luster Candy. Will need an Ice transfer.
• Sarasvati: 195 magic, Purple has Back Attack, p3 has 10% damage. Mabufula (100 power AoE). Will need a Resist Fire transfer.

Other options worth considering:

• Cleopatra: casts Spirit Chains of Corrosion at the beginning of the battle, greatly reducing enemy defenses even at higher levels. Doesn't need an Ice transfer, as she can simply skip her turn.
  • Avoid using Radiant Blast while Mithras is alive, as he will heal his team by 5% of their HP if his version of Covenant Bless connects.
  • Her Reverse damage reduction in Peerless Beauty and Panel 2 don't work under Hell's Park Underside rules.
• Rahab: 214 strength, p1 has 15% damage, p3 has 20%. If p2, has 15% weak-point damage aura. Sea Dragon's Fury (200-350 power single-target w/ +50% crit). Will need a Resist Fire transfer.
  • Suppression prevents him from gaining Might or casting ATK buffs, so his damage may be lower than expected. Due to this, he will also need someone else to cast stat buffs in order to ramp his unique's power.
• Quetzalcoatl: 178 magic, p1 has 25% AoE damage. If p2, has a 20% damage and +1 MP recovery aura for Dragon allies (helpful to boost Illuyanka or Rahab). Will need an Ice transfer.
• Izanami: 226 magic (246 with maxed Yomotsu Okami), has Merciless Blow. Will need an Ice transfer and Resist Fire. Her panels do not help an Ice build, so you can use a p0 copy (or just unlock p2 for the +100 MATK).
• Ishtar: 247 magic, Mesopotamian Star casts Luster Candy and Debilitate. Will need an Ice transfer.
• Lakshmi: 248 magic. Will need an Ice transfer.
