Which one is better for Drake in the Prisma Illya event? Though my Drake is only level 80.
Also, it's not an MLB Origin Bullet. I only need one more.
Kaleid Ruby since it's not MLB. But if you can MLB it origin bullet may be better (affects more cards where kaleido only affects 3 albeit for 50% vs 40%) initially. Once you've mlbed Kaleid Ruby though definitely Kaleid Ruby. MLBed K Ruby grants 100% extra damage on buster for her which far outclasses all else as it applies to half of her cards those cards also being her main damage dealing cards.
Definitely Kaleid Ruby in raids(even not in raids)
K.ruby's event bonus is +50% damage for female servants and Buster damage +50% in world end matches(raids). so it's a no brainer to use k.ruby in raids.
edit: those are only the event bonus. the card's main effect is buster+10% and np damage+8%
that's a flat [(+50% damage boost) + (50% buster damage in raids) + (10% buster damage) + (8% np damage)] compared to a NMLB origin bullet which gives a 35% bonus damage to casters.
