Silvie and Gabriela's BB utility buffs aren't necessarily considered buff-clashes if they appear on one's BB and the other's SBB and vice-versa and if they provide the same potency. That's not what buff-clashing is at all. Silvie's tri-buff and Elimo's Def and Rec buffs are considered buff-clashes, but as stated before, the difference is so small that it's insignificant. The similar thing can be said about Gabriela's BB-on-hit enhancement. That 5-8 BC BB-on-hit is so unnoticable that the enhancement isn't worth the 20 SP you're spending.

And about the BB-on-hit that Silvie has on her BB, it IS useful. It serves as an easy access whenever you desperately need it, especially because in hard content, BC drop resistance becomes such a problem that you'd have to adjust to it.
