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.

Tam Lin (Underside) effect overview

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

Colors

• Clear for the fusibles ruleset.

Skill Transfer

• Skill priority from greatest to least damage is: Wind Slash (Underside) > Killing Wind (Underside) > (any magic-based attack).

Brands

• PATK% War, if using a strength-based attack (such as Wind Slash (Underside))
• MATK% Spell, if using a magic-based attack.
• Due to his MP discount, Divine's MP regen is probably not necessary.

Misc notes

• In most cases, just build him for magic, even though his MATK sucks. This way, you boost the damage of his own attacks as well as his AoE chain.
• Building PATK is worse if using regular Wind Slash, as you lose damage by not boosting the chain AoE. However, Wind Slash (Underside) does enough damage by itself to overtake the loss, and is slightly better damage overall.

Jack Frost (Underside) effect overview

• Self gets Concentrate (2.25x damage) on his first action - this is about 63% damage on average across his 2 actions on the first turn. Also gets 50% HP and immunity to Spirit Chains of Suppression.

Colors

• (Any)

Skill Transfer

• Use Zandyne.
• Jack Frost does not have any MP discounts, so 7 MP skills such as Killing Wind may be too expensive to cast repeatedly.
  • Killing Wind (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.

Brands

• MATK% Spell or Divine.

Misc notes

• If using Killing Wind (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.

Tsukuyomi Skills Resist Phys Force Boost Brands MATK% Divine or Spell Requirements -

Tam Lin Skills Tam Lin (Underside) Zandyne Brands MATK% Spell Requirements -

Team notes:

• Cleopatra: casts Spirit Chains of Corrosion at the beginning of the battle, greatly reducing enemy defenses even at higher levels. Doesn't need a Force transfer, as she can simply skip her turn.
  • Her Reverse damage reduction in Peerless Beauty and Panel 2 don't work under Hell's Park Underside rules.
• Cu Chulainn A: 201 strength, high crit rate, P3 has 20% damage. Has an aura for all allies: 10% Phys/Force damage and 10% AoE/Random damage. Barbed Spear (105 power AoE + ramping 50-125 power Random).
• Cu Chulainn: 190 magic, P1 has 20% damage, P3 has 20% damage, P4 has 25% damage. Mazandyne (120 power AoE).
• Tsukuyomi is weak to Phys, so he has Resist Phys transferred to cover it.
  • Damage-wise, he prefers using max-level Zanma plus a damage booster, over using Zandyne with no damage booster. Zanma can be leveled cheaply using 3★ fodder.
  • His color does not really matter, unless you specifically need more HP from Purple.

Other options worth considering:

• Izanami: 226 magic (246 with maxed Yomotsu Okami), has Merciless Blow. Will need a Force transfer. Her panels do not help a Force build, so you can use a p0 copy (or just unlock p2 for the +100 MATK).
• Norn: 193 magic, has Merciless Blow. Automatic cast of Luster Candy, and can do decent damage if given a Force transfer.
• Ishtar: 247 magic, Mesopotamian Star casts Luster Candy and Debilitate. Will need a Force transfer.
• Lakshmi: 248 magic. Killing Wind (180 power single).
• Quetzalcoatl: 178 magic, P1 has 25% AoE damage. P2 has an aura for Dragons: 20% damage and +1 MP regen. Mazandyne (120 power AoE).

• Illuyanka: 175 mag. Zanma (140 power single) and Mazanma (100 power AoE).
• Kurama Tengu: 134 mag. Zanma (140 power single).
