★1 +1 Gathering
★2 +1 Farming
★3 +1 Planting
★4 +1 to every job
Condense it at a Pal Essence Condenser (unlocks at Lv 14) using 4, 8, 12 and 24 more Beegarde for each star (48 in all). Or feed it Starfruit ☆1 to ☆4 from the Medal trader, or a Ripe Starfruit from the Bounty token exchange. The Condenser shows the new levels before you confirm.
Farming's place in that order isn't confirmed yet, so check the Condenser preview for this one.
