Ok, so I made my porutu 80 on Europa. I put 80 points to attack, but the last 2 skills on the skill list won't work, they stay as an "?" mark as any other skill that is not obtained. Please fix this bug, would be awesome to try the skills out?
you need to go to portu npc next to sundries in lufer or el morad,
get the mission unlock quests for 75 and 80 skill,
complete the quests providing necessary items
