well, now got 40% or more elemental atk eidolons for all 6 elements

-Echidna (60% dark/fire)
-Tiamat (40% water, combo rate up)
-Amaltheia (40% wind, thunder res 10%)
-barong (40% light, dark res 10%)
-Amaru (45% thunder)

just gotta keep building from there, starting with getting more than just my light grid to 100% assault or higher (next closest is fire at around 75%)

besides, all my grids have a nice potential on assault (except maybe dark), so gacha farming it is while hopefully finding better weapons in events (unlike this damn SSR weapon from here that i got 6 times...)
