What is 'Eludi. Stat Buff'

P5X features a non-combat position called 'Elucidator'.
Characters in this position have cooldowns for each action, which decrease whenever an ally acts. They primarily function by providing buffs to allies or debuffs to enemies.
You might wonder if stats are important, but due to the skill effect 'Eludi. Stat Buff', raising stats is actually quite significant.

Instead of a HIGHLIGHT, all Elucidator Phantom Thieves have the 'Eludi. Stat Buff' passive in their 4th skill slot, which grants a portion of the Elucidator's stats to the entire party.

5-star Elucidators grant 20% of their stats, while 4-star Elucidators grant 15% to allies.
In other words, if an Elucidator has a 40% Crit Rate, the entire party's Crit Rate increases by 8% for a 5-star character and 6% for a 4-star character.

If you want to check the actual increased values, you can tap the magnifying glass in the character screen and then the Elucidator icon, or tap the Elucidator icon in the combat lineup.

Since the commonly used 'Labor' Revelation (as of 26.02.09 KR) consistently occupies a slot for Elucidators, and strengthening the Elucidator through the 'Labor' Revelation effectively leads to strengthening the entire party, obtaining good 'Labor' Revelations is crucial.
