Here's the math on elemental buffing.
First, what you need to know, is that bonus damage from weapons (+20%), armors (+20%), en-element (+50% - +120%), and chain field effect (+20%/+50%) all stack together additively.

The Glint allows en-element stacking of up to 3 levels. This effect needs to be refreshed every 25 seconds, but you can use other sources of en-element to rise the en-element level. So Glint->USB->USB gets you to level 3. If you don't use the Glint again within 25 seconds, you drop to level 1, otherwise you can stay at level 3.

En-element level 1 gives +50% to abilities and +80% to soulbreaks.
Level 2 gives +80% to abilities and +100% to soulbreaks
Level 3 gives +120% to both abilities and soulbreaks.

So if you have a weapon, an armor and level 1 en-element, you get +20%+20%+50% = +90% (1.9)
If you have a weapon, an armor and a level 3 en-element, you get +20%+20%+120% = +160% (2.6)

I hope that didn't give you too much of a headache.
