since ROM introducing the Combat Time system, when you deplete them you gain less exp and drop rate, to use it efficiently my logic is we have to do this:

1. Start your day listening through music at Guild Hall/South Prontera to extend your combat time. (because listening after you exceed doesnt give back the effect since you're already exceed the daily, even if you reduce it your minute already exceed the Limit Bonus anyway and soon you'll got a new combat time anyway at server reset).

2. While your combat time is available: leveling at a spot around your level, and/or farming any item you desire while use monster resistance. You can do it while questing too if the monster level or drops is the one you looking for.

3. When it exceed your combat time limit, then you should do questing and daily.

Am i right/wrong or is there any better solution?
Also does rift exp/droprate affected by combat time? if not then rift should be done after your combat time depleted.

feel free to discuss since i am on open book and ear mode. thanks for chimming in.

EDIT: so two of redditors actually mentioned that combat time we gain from music is actually separate from the actual gauge. So you can listened the music anytime as long as you spend it that day youll be fine. Skip to step 2 and 3 and do step 1 anytime you want
