Tips:

1. level up slowly, reason being is because there's a level cap

2. get into the habit of not collecting resources once you enter the kingdom scene and just ignore the resources and let them float/sit there

3. get a feel for how much the percentage bar increases every time you collect all the resources in one go, that way you can 'time' your kingdom level up to whenever you need it (ie. beginning of an event that you want to rank in, an event where you want to collect certain cards)

only collect when:

1. you don't have enough resources to refill soldier count

2. your alliance has free resource donation space

3. like you said, you need vitality and battle points
