Condense it at a Pal Essence Condenser (unlocks at Lv 14) using 4, 8, 12 and 24 more Warsect 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.
Hauling: grabs up to 40 items from a pile per trip (Transporting 5), runs to it at 500 and carries at 110. At four stars: Transporting 7, 120 items per trip. Compare all haulers
The game picks the drop list by level: a wild Warsect at Lv 70 or higher uses the World Tree list instead of the normal one, and at Lv 80 the Aura list. World Tree farming guide
