The battlefield is littered with various objects that will yield items when destroyed. Staying true to the source material, players can hack blades of grass to reveal hearts, rupees (game currency), or SP fragments.
Within the bases, you'll find color-coded jars. Yellow jars contain whole SPs or SP Fragments, Green jars drop Magic vials that recover your Focus Spirit, red jars will contain hearts (HP) (but sometimes they also carry big hearts and fill SP pieces), and finally the brown, normal jar that will contain rupees.
There are also chests scattered in the area. Red Chests contain valuable items like Tools, Heart Pieces, Heart Containers, and Sealed Weapons. These chests don't appear by normal means. They're usually hidden under breakable boulders, behind obstacles that require specific tools to manipulate (e.g. fake walls) , in secret locations, or they'll just appear after capturing a specific base/ keep.
Can you go back k to a previous scenario to get heart containers and pieces as well as skulltillas?
