as everyone has said f keys are a must. also in dmm having an escape is crucial especially since you can use them to chase your enemies if they run. also having efficient gear setups that give not just high dps but good def stats. like using splitbark even though it has lower magic attack bonuses, its melee defence could end up saving you. id try to bring as few switches as possible really since you'll end up with less misclicks and more space for food
