Explore the game world. Gather all herbals and resources (use the TAB key to highlight all interactive objects from the surrounding area). Your inventory has unlimited space and gathered items can be later used for weapon upgrading and creating potions. You can sell then as well.
Rest in inns whenever you need. For a rather small price you will receive stats bonus without the need of using camp materials. Resting in your stronghold is free and after upgrading it gives various temporary stats boost (although lover than in inns).
Rely on camping supplies when going on longer trips. They’re your best help if retreating to the keep or to the nearest town would be time-consuming or when you’re know that you’re about to take part in a difficult battle with a boss or a group of strong enemies. Sadly you’re allowed to store a very limited number of camping supplies – no more than 6 for the easy difficulty setting, no more than 4 for normal and only 2 for the high difficulty level. You can replenish your camping supplies by finding them in the game world or by buying them from the merchants. Important – Your team is not allowed to rest using camping supplies if it’s engaged in battle or if it has been spotted by one of the enemies. Additionally you may be forbidden from using camping supplies if you’re in a city or inside a small building.
While being in buildings and dungeons, search chests and barrels. Many time you will find something interesting inside.
When exploring, use scouting mode. If you see something suspicious or you’re in narrow locations (dungeons, rooms), use scouting mode that not only allows you to see traps, but hidden lockers and switches as well. For example, it allows you to find a hidden door that will lead you to a shortcut or inaccessible in other way treasure.
Sometimes valuable items can be found in not so obvious places like bookshelves or in vases.
Complete side quests. Not only they increase your party level, but give you dozens of hours of additional gameplay.
Talk with characters that have unique name. If a character name is marked with yellow color, it means you can “touch” his soul and read a short history of that person. Characters that give side quests usually talk when you walk near them.
Carry with you lockpick, rope with grappling hook, hammer and chisel. You should have two or three pieces of each. It will allow you to get to hardly accessible places. You can purchase all of the tools mentioned above from certain merchants, however you will also find plenty of them as a result of careful exploration.
Visit your stronghold from time to time. Try to expand it regularly. You will increase possibility of event occurrence and will gain other profits.
Use crafting – alchemy, enchanting and scroll making. You know all the recipes from the beginning of the game, all you need is to get required level. By using potions or scrolls you improve your chances when fighting stronger enemies. Certain requirements must be met to create some items, like using spells or having specific lore level.
Learn how to manipulate time. Not the active pause during combat, but the possibility to speed and slow the game speed. You can speed up the game when you travel through already explored location and you want to get to a certain point, by doing it you will avoid waiting. Slowing the game is useful when sneaking – it gives you certainty that you will see enemy before he sees you. By default you control time with the “s” and “d” keys.
