The most important thing to understand about blood quality management is watching those telegraphed drains during intense fights. Your quality starts dropping faster in combat, so getting that 90%+ quality before engaging is crucial - target those elite enemies in silverlight hills for the best blood. Warrior blood gives you solid physical damage while scholar blood amplifies spell power, and the timing here matters since switching blood mid-fight resets all your bonuses.

When you're actually in the fight, pay close attention to that blood meter in the bottom left. Once it drops below 60%, you'll want to focus on burst damage rather than trying to feed on nearby enemies. Scholar blood pairs really well with reaper weapons or chaos volley since you can sustain yourself without draining the blood quality faster. Time those big ultimate abilities like arctic leap when your blood quality is still in that peak window, usually the first quarter of your blood duration.

Good to know - worker blood actually helps during daytime fights by reducing sun exposure, which indirectly preserves your blood quality. Map out a route through high-tier enemy zones before tackling major bosses, this lets you start encounters with maximum quality and the right blood type for your build. Just remember that combat accelerates the drain, so position yourself smart and don't waste those precious high-tier bonuses running around unnecessarily.
