Yellow core casting dimensional Spirit spells...wat!? each dimensional spell costs 6 times It's tier in mana and Spirit magic is also several times more draining since you don't use world energy. a single Spirit blink is like firing 20 t3 fireballs and at yellow core he should struggle to fire just one. let's not even start on bloodline ability spam... Must be nice that most readers either don't remember or don't care about world lore so the author can ignore it.
I don't even understand how the mine hasn't exploded yet with such powerful Crystals no matter how they manipulate their mana or spells. Then again, how can yellow corea spam powerful spells? Even if they are empowered, it's already been a magic law of this book that each core has it's limit to spells they can cast. If not Narlond would be OP with dual cores and Lith-Solus Combination shouldn't have a match of anyone their rank. Or are these guys gonna be strong as white core by the time they get to blue/violet core? Lith still relies heavily on Solus which he should have matured past that stage, it's over a 1000+ chapters now and he's been awakened and had self awareness since a baby.
