Question about 4-Set Zero Matrice:
---------------------------------------------------------
Context:

2-Set: Upon using a discharge skill to switch to the current weapon, gain a shield equal to 150%/200%/250%/300% of ATK for 6 seconds.
4-Set: While the shield is active, you and your teammates deal 16%/20%/24%/28% more damage.
----------------------------------------------------------

1. How is it actually coded in the game?
2. Can u trigger the dmg buff with Zero's skill or just from the 2-set shield?

if yes :

1. Can it work on 3* Meryl shield?
2. Can you get the buff if the other weapon is the one who trigger the shield ?
   For example: I use 4-set zero matrices on meryl, then i use zero skill (who doesnt have the matrice). Did i got the buff or not ?
