Just example emerald dragonfly 800lp, 2w, 6exp cost, 1 slot, 8 hours to study. Pretty common just go find first swamp and have water to replenish stamina.(or use horse)
And i just found Washed-up bladderwrack 763lp(10-11-10) 3w, 6exp cost, 2 slot, 8 hours. It is first i found so far when i get 15*18, so its not sommon. More weight, more slots, less lp
