Before entering Rune Research lab in Seign's Route check if you have heals in your inventory and try not to waste MP against Regular mobs, you''ll face 3 or was it 4 boss fights consecutively later on or you can just runeshard of return your way back to restock before progressing the story
Boss Fight - Chimera this is somewhat a tough boss fight if you're not prepared, save your Cannon fire/Gimmick when Chimera starts Charging to stun him, use water viel to negate/reduce dmg taken, Ready up Recovery(i have it on Seign and Hildi). And save up a bit of MP for Pohl later when boss starts inflicting paralysis(Earth heal for debuff).
