Leveling up on mindreading is the same as leveling up on any other skill, such as firewall or ghost.
Once you have skill points to spend, go into your skills and look under Dragon Slayer. Mindread is the first one up the top which looks like a humans head.
Click on it to allocate points.
Please note that with certain skills, you have to be at a certain level before you can allocate more points to a skill.
Romon and the scrying stone have nothing to do with the main quest. It was only a side quest.
To get to Lovis. You will remember in the actual tower a waypoint shrine with gates blocking the path upwards, right? (You would have had to open most of them to get to the Stone).
Anyway, follow the path upwards and after you open the last gate you will see a door on the right. Go inside. Inside you will find a circular room with a glowing green light in the middle. Turn left and go over the first rubble heap, before turning around. You will see a corpse. Search the corpse and you will find a spell. Use the spell and a lever will appear. Use the lever.
You will then be in a throne room. Go over to the throne and interact with the pedestal. Answer all the questions correctly and you will be able to speak to Lovis.
You never face Maxos seeing as Maxos is dead. I think you are referring to Amdusias, and the answer is no seeing as you cannot become a Dragon at that point of time.
To beat Amdusias you will need a vile of his blood, Dragon Scales and the Orbis Arcesso Part Two.
To become a Dragon, you will need to defeat Razakel and Laiken in the Battle Tower, and acquire the Dragon Stone which is also in the Battle Tower.
This is part of the main game so you will get to it soon.
First off, it should be known that not all barriers can be taken down.
So, to take down the barriers in the beginning, starting from the first waterfall you see in Orobas Fjords, hug the cliff on the left and head towards the nest under the barrier on the left. Fly across it and on the cliff above it you will see a teleporter. Use the teleport you are after. It will take you to a bunker in the anti-dragon zone. Enter the bunker and fight two members of the Black Ring. After you have defeated them, go up the stairs; decide the fate of two more Black Ring warriors, before going to the end of the bunker and interacting with three levers. This will remove all the Dragon Barriers in the beginning.
Now, the barrier surrounding the small towns, you cannot remove.
To remove the anti-dragon shields at the far end of the Fjords, you will need to destroy certain goblin constructions. These constructions are illuminated by a blue energy force surrounding them. You will need to destroy them to bring down the barriers. Using fireball is a great tool for destroying them.
