If you've already seen my first guide for Tegmine, I'll put the important changes in a comment below.

This is the hardest 10-man trial so far. The requirements are stiff and there's not much leeway outside of 5* base units such as: LM Fina, Ayaka, physical chainers, and Basch.

A level 30 3* Shiva with 100% Evoke Damage is required for this.

Recommended Team

Your physical dps, healer, aoe physical cover tank, summoner and provoke tank should all have Paralyze resist!

Actual Fight

Phase 1 (59% - 100%)

This phase is relatively easy compared to phase 2. Tegmine gets a preemptive which will cast insta-death on a unit, hopefully this lands on Ozetta, but if not, then it's still fine. Have non-essential units Ozetta on your starting team. Basically not Rosa/Mystea/Meliadoul.

Revive the KOed unit and on the next turn sub in Killian. You want to max out his Gear-Up, so do Ignition 4x Gear-up. Make sure he has enough MP through Rosa's regen (128 MP needed) and cast Ignition again. Sub him out for WoL. WoL should cast his AoE Cover (don't worry, Tegmine always attacks with magic first). Finally, sub in Lexa and have her deal damage.

Turn Setup:

Ozetta: Mime-Impregnable -> Defend -> Defend. She may die if you get bad RNG.

Rosa: Bless/DC Curaga. Raise when necessary. Sub in Garnet if you need more healing.

Meliadoul: Crush Weapon -> Primal Instinct (Barusa TMR skill) -> Chantage on Ozetta.

Lexa: DC Aeroja or Tornado Aeroja. Osmose if necessary.

Mystea: AoE Magic Cover -> Frozen Hurricane or DC Cura/Protectga/Shellga -> Frozen Hurricane or DC Cura/Protectga/Shellga. Frozen Hurricane is high priority.

Transition into Phase 2:

When you know you can bring Tegmine down to 59% (be mindful of how much damage a chained Aeroja does! Crossing into phase 2 without WoL is an instant failed run), sub out Mystea for WoL. Make sure this is not on a turn where you need to break OR Primal Instinct (i.e. not a 3n 1 or 3n 2 turn for me). This is explained on WoL's turn setup.

Checklist before doing this:

• WoL has AoE Cover up

• Killian has max stacked Gear-Up and Ignition buff

Defend with WoL, cast Cradle of Horns with Ozetta, and Primal Instinct with Meliadoul. Heal/Bless with Rosa and cross into Phase 2 with Lexa. You should survive easily with this.

Phase 2 (39% - 59%)

Sub out Lexa for Garnet.

This is where things get difficult due to RNG. If you damage/attack it during your turn, it will use retaliate with one of these:

• 33% chance: 400% AoE 1 Hit Magic Attack & 100% Poison/Paralyze/Virus
• 33% chance: AoE 3 Turn -60% ATK/DEF Debuff & AoE 3 Turn -75% Water Resist
• 33% chance: AoE 3 Turn -60% MAG/SPR Debuff & AoE 3 Turn -75% Water Resist
• Otherwise: 450% ST 1 Hit Magic Attack & 100% Poison

It always uses a 3.5x AoE physical attack and every normal attack has a chance to be a 3x AoE attack (20%) which makes tanking it very hard if you get bad RNG (evade <100% is basically countering RNG with RNG.) I got quite lucky with this run.

Turn Setup:

Ozetta: Mime-Impregnable -> Cradle of Horns -> Cradle of Horns.

Rosa: Bless/DC Curaga. If Diseased or DEF/SPR broken, use Miracle when possible. Raise when necessary.

Meliadoul: Crush Weapon -> Primal Instinct (Barusa TMR skill) -> Chantage on WoL.

Garnet: Heal if necessary (covering for Rosa when she needs to use Bless). Prayer to Eidolons/Summon (Only summon when you break with Meliadoul. This limits the Tegmine's counter to once every 3 turns.) Shiva is very strong so do not summon her twice. Use a weaker one like Ramuh/Bahamut.

WoL: AoE Physical Cover -> Defend -> Defend. You want him on a one turn difference from Meliadoul/Ozetta. This allows him to defend when you damage Tegmine (Magic Counter will deal a lot of damage.)

Transition into Phase 3:

When Tegmine is around 45% HP, apply Crazy Day with Rosa (do this on a turn when you damage Tegmine). Then cross into Phase 3 by quadcasting Gear-Up with Killian. You need to have full Esper Gauge before doing this and Meliadoul's LB (should be up if WoL has Counter).

Phase 3 (0-39%)

Ideally, you do not get the AoE Magic retaliation or Killian/Meliadoul will die. This could mean that you just lost the fight depending on Shiva's damage variance. If not, you get the clear and the LB mission as well.

Team should be: Garnet, Wadow, Yuri, Killian, Meliadoul.

Turn Setup:

Wadow/Yuri: Earthsplit Evasion 2

Garnet: Summon Shiva

Killian: Gear-Up

Meliadoul: LB

And Tegmine completed!
