Taking, using and dropping items (touch-based).
Sometimes monsters drop objects after they have been killed. To pick up loot, simply tap the item and your character will move on the field with the item and pick it up.
To use items (i.e. to drink potions, to use a sword, to put on or take off armour, etc.), simply touch the item you would like to use. A small menu will open up. There, tap the tool symbol to use the item.
To drop an item on the map, simply touch upon the item in your inventory. A small menu will open up. Tap the hand symbol to drop the item at your character's feet.
