The magic watering can may be lost upon death, but it can be replaced by talking to the Fairy Queen.
It can be used to water saplings that are grown in a plant pot, negating the constant need to refill the watering can with a bucket of water or another water source. Flowers and allotments can also be watered to negate chances of disease for that particular growth stage. It can also be used to plant items in Player-owned houses.
If a player has a normal watering can and a magic watering can in their inventory and attempts to store one with the leprechaun, only the magic one will be shown for storage.
It was previously possible to get more than one magic watering can by storing one in a Tool Leprechaun and then asking the Fairy Queen for a replacement. Anyone who had obtained more than one magic watering can before this bug was fixed still has the extra(s) unless they destroyed them or added them to their tool belt.
Despite the fact that it is a bottomless source of water, it cannot be used to fill buckets, waterskins, or other similar items; however, it can fill other watering cans.
