What does Infusion Hand Seal Relic Do?

[phampire]

Infusion Hand Seal Relic:
Increases all wands' secondary slot charge efficiency by 20%

Not sure exactly what that means. Is it mana regen? Or is it the 2nd "bonus stat" of wands? Or is it the second spell slot from the left?

[|ÅΩ| Mayu]

It'S the slots, that are like "charge x, when standing still/walk/use spells, and so on"
Like u have the normal slots on the left and the "special" decondary slots on the wight of the wand
