Thank you

i got your answers sowwie i didn't get here sooner i just found out bout this place ^.^; the boss you are refering to is king vermin his hp is 39857 use garment grids that use the fire eater ability avoid casting fire on king vermin he absorbs it and loves to cast it so when fire eater is equipped he will do the healing not you have a white mage for healing and have a black mage belt out ice spells he isn't That hard once you have this

for sophia's Q guardian beast is somewhat easy if you are fairly leveled up his hp is 2,886 he is weak against all elements cept gravity so use a mage use third level magic and have a songstress to use darkness dance also have a white mage to heal status and hp
