2. 📈 Level and Stat Efficiency: Why Level 80 is Recommended
  • ✅ Level 80 is recommended for Xaihi.
  • ⚠️ When leveling from 80 to 90, the stat increase efficiency is low compared to the resources spent.
  • ✅ As a 5-star support, it's worth investing in to increase the main dealer's damage.
00:55 - 02:56
3. ⚔️ Skill Analysis: The Key is Arts Amplification and Frost Application
  • Battle Skill: Summons a cube that follows the main character, providing HP recovery or Arts amplification.
  • Arts Amplification: Grants Arts amplification when activated at full HP, increasing by 13% at level 9 and 15% at level 12. Level 9 or higher is recommended.
  • Chain Skill: Can be used after consuming all cubes, inflicting Frost damage and applying Frost.
  • Ultimate: Grants Frost amplification and Natural amplification to the entire team.

⚠️ The healing amount is low, so it's best to use it with another character that has healing.
02:57 - 03:48
4. 🧠 Ultimate Amplification Mechanism: How to Utilize the Intelligence Stat
  • ✅ The ultimate consists of a base amplification and an additional amplification based on intelligence.
  • ✅ The maximum intelligence amplification is 36%, and it is applied separately from the base amplification.
  • ✅ You should aim for 1200 intelligence to get a maximum of 60% amplification.
  • ✅ It is better to prioritize intelligence over the main stat, Willpower, in equipment.
03:49 - 06:36
5. 🛠️ Weapon Recommendations: Explosive Unit vs. Knighthood Spirit
  • ✅ Explosive Unit and Knighthood Spirit are recommended as development weapons.
  • Knighthood Spirit: Has an attack power increase effect when healing, so it can be used by both Lara and Yvonne.
  • Explosive Unit: You can get intelligence by increasing main and sub stats.
  • ✅ If you don't have either, it's okay to use Adele's exclusive weapon.

⚠️ Xaihi's exclusive weapon is not recommended because it is a healing weapon.
06:37 - 07:37
6. 🔋 Ultimate Charge Efficiency: Conditions for 1 Cycle 1 Ultimate
  • ✅ Lara's party charges a total of 29.5 ultimate gauge per cycle.
  • ✅ To get 1 ultimate per cycle, you need an ultimate charge efficiency of 180% or higher.
  • ✅ You can get 1 ultimate per cycle by using doping (Meat Conference, Elixir of Confusion).
07:38 - 09:34
7. ⚙️ Equipment Setup: Food Set vs. Unset Pioneer
  • ✅ You need to set up equipment focusing on ultimate charge efficiency and intelligence.
  • ✅ Recommended sets are the Food Set and Unset Pioneer.
  • Food Set: It's the best set right now, but it's best to only have one person in the party use it because it doesn't stack.
  • Unset: Use single parts with intelligence and ultimate charge efficiency.

8. ⭐ Breakthrough and Affection: Key Breakthroughs are 2, 1, and 5
  • ✅ Key breakthroughs are ultimate gauge reduction (2 breakthrough), additional amplification increase (1 breakthrough, 5 breakthrough).
  • ✅ Affection is Willpower, so it's not essential, but you can invest in science and intelligence training.
  • ✅ Preferred items are Canyon Industry's carefully selected trendy items (Duck Camera, Stargate Lock).
