1) GIVE +10 stats each point

2)yes you will need reskill

3)yes you need do the job quest (exept 115 job if you do this you hp decrease )

4)no but you hp/def/dmg decrease but it increase when you lvling

5)your items not be erased but if you put you +110 itemes you will get that lvl for can use again

6)no you dont get more stats points when you lvlup
