Lydia's Rescue Journey Training & Recommended Arcana

Recommended Arcana Deck: Lydia organization

[Key Arcana Deck & Rescue Journey Points]
  • •Since it is a debuffer, we recommend training with strength and concentration in mind └There is a debuff that lowers Effect RES, but in the end you want Effect Hit to apply that debuff.
  • •It is recommended that Stellar Archive has Power +2 to strengthen its power.
  • •Critical potential, attack type, and Effect Hit type are recommended.

Lydia's Strengths & How to Use

Multiple Action Gauge effects added

Due to balance adjustments, you have gained the effect of increasing your own Action Gauge and decreasing the enemy's Action Gauge.

Additionally, the effect of Nova Burst has changed from ``Grants unknown spell when using Ultimate Skill'' to ``Gives Action Gauge reduction when using Basic Skill'', and now all skills can apply Action Gauge related effects.

Since the unknown spell disappeared with the burst, it can now be applied with the Ultimate Skill, so it is OK to understand that the Action Gauge can now be simply reduced.

Including the original speed debuff, it has evolved into a performance that specializes in hindering enemy actions.

Lots of speed debuffs

Lydia can apply weakening effects with all skills, including the effect of Unique Passive, and is especially good at speed debuffs.

With two types of speed debuffs, unique debuffs and general debuffs, you can significantly reduce the enemy's speed, so it will greatly contribute to the speed of your allies.

Increases firepower when enemy is weakened

Lydia has a passive effect that increases ATK Up multiplier due to Unique Passive by attacking when the enemy is in a weakened state.

This passive effect can stack up to 5 times, and is a powerful effect that provides a permanent attack buff of up to 30%, so you should always keep the enemy in a weakened state when attacking with Lydia.

Effect RES debuff also supports weakened allies

Lydia's unique debuff "Unknown Spell" combines speed debuff and Effect RES debuff, which increases the debuff success rate.

A nice point is that it makes it easier to operate not only yourself but also other debuffers.

■There is also a Passive Effect Hit.

By adding up to 30% Effect Hit to Passive, it has become even easier to apply debuffs to yourself.

If you have this much, you can think about increasing the effect of equipment to firepower, so if your development is progressing, consider changing equipment.
