There is a pdf manual on the DVD (in a 'manual' folder), and it is installed on the hard drive ('..\'Divinity II - Developers Cut\manuel_en.pdf') and accessible from the Starm menu, All Programs, Divinity Anthology, Divinity II - Developer's Cut, Manual shortcut.
On level 7 you have probably met the alchemist, but will not have made it to the enchanter (level 10-13 would be more appropriate to find him) to be able to add/remove/change enchantments on equipment.
If you have nothing left to do in the starting section of Broken Valley, then first take out the goblins east along the mountain from where you met Talana, or west and up a mountain trail. Both those locations contain a hatch to the derelict tunnel, where you can level some more (and get a bit of loot) before taking on the skeletons around Lovis' tower.
There is no rush to get to Lovis' tower (or any main plot quest, for that matter).
Start the Developer Mode version of the game, and after starting/loading a game, hit F11 to bring up the cheat window (you can then increase your level, stats, skills, gold, give yourself equipment, etc).
Welcome to the forum.
