How HP and AS regen works.

When you explore in the story or tower, the HP regen timer resets. So let's say you are at 50 seconds of your HP regen, so you are only 10 seconds away from getting an extra 1 HP. When you explore, that time resets so you are back to 60 seconds away from the next 1 HP.

This means it is better if you explore only once in a while (e.g. whenever you have over 100 HP). Do not try to explore as soon as you are able to (e.g. every 8 HP). The second method will end up costing you a lot of HP in the long run.

AS is in a similar situation. When you start a fight with someone, your AS starts regen timer resets. The regen will continue again after the battle screen ends. Let's say your are currenty at 50 seconds of your AS regen, so you are 10 seconds away. When you start a fight, you will lose your AS as per your team. But your AS won't regen again until after you exit that battle screen.
