• A co-op player can join you from the very beginning in the character customization screen.
  
• If you'd like to create your builds around the two main companions in the game who take part in the story, a mage using air and water magic. The other is a two-handed melee weapon specialist with skills in Man-at-Arms. Of course, later on in the game you can choose from plenty of mercenaries.
  
• Whichever character you expect to have in the lead during conversations should be the one in the SECOND character-creation slot. In certain conversations (such as the ones with Zixzax when you go to the End of Time after getting a new Star Stone), the character from the second slot will automatically be the one to do the talking, regardless of who you're controlling.
  
• In my opinion, blacksmith, crafting and loremaster aren't necessary abilities to sink points into unless it's something you think you'd find yourself enjoying (and they are enjoyable). Money is abundant, loot is good and I'm typically able to do what I need simply by switching to armors with buffs to these stats while in town.
  
• Pet Pal is a great ability to have with one of your characters. Animals tend to drop hints on quests and give you further possible ways to complete quests.
  
• Each class of magic has their own summon skills.
  
• You can change your appearance and respect points later on in the game.

• World is persistent. All items dropped or stashed will stay where they are forever.
  
• Loot dropped from chests and enemies are randomized.
  
• Pressing 'L' and clicking the dialogue tab will allow your co-op partner to follow the dialogue.
  
• Holding shift while dragging an item in your inventory splits stacks.
  
• Left click is for action/movement. Right click is to cancel action/movement.
  
• Merchants goods are refreshed overtime. Any items that were sold to the merchant stay there to be bought back.
  
• Steal everything, take everything (without getting caught). Enemies don't respawn and can be wiped out. Gold is in abundance, XP is more rare.
  
• It takes 2 ability points to get an ability to lvl 2, 3 to lvl 3 etc.
  
• You can assign which player controls what characters in the Assign menu, which can be accessed by hitting Esc.
  
• Once in the town, head northwest for lower level monsters.
  
• Telekinesis allows you to pick up items farther than you can reach.
  
• While in a cloud or surface of fire or poison, etc. avoid walking. Each step causes damage, rather than per turn while standing.
  
• On the left hand side of the screen, dragging the portriat of one character onto another will cause those characters to follow eachother. Pulling them away will do the opposite.
  
• Combat is much more easy when elements (fire, poison, water, ice, electricity) are used to your advantage.
  
• Use sneaking to create an ambush on tougher enemies.
  
• You can control a character outside of combat in real-time if they are far enough away from the fight and haven't been spotted. Getting an enemy groups attention and having a rogue character sneak behind for a backstab is a good tactic.
  
• Giving extra gold to NPC's while bartering will raise their attitude towards to. Bartering in general and completing quests will do the same.
  
• Having your weapon drawn when talking to NPC's reduces their attitude towards you.
  
• NPC's with a low attitude tend to charge more for items and purchase your items for less.
  
• NPC's with a high attitude might give you more information and will turn a blind eye while you steal less valuable items.
  
• You can have up to 2 companions (4 characters in total). Two can be found in the first town.
  
• You can save the game whenever you want, however you want (during combat and dialogue). Haven't had any issues, even in multiplayer. Comes right back to where you left it.
  
• Using a fire attack on a fire creature heals that creature. The same goes for every element.
  
• Charm, intimitade and reason during dialogue are are all affected by the charm ability and simply change the dialogue based on what you choose.
  
• The number next to a buff or debuff is how many turns your affected by it.
  
• Dropping an item on any NPC will cause them to attack you.
  
• After accidently attacking a friendly NPC, some have had luck fleeing NPC's and coming back later to remove the hostility.
  
• 100% chance in combat does not mean a 100% guarunteed hit when it comes to debuffs (Willpower and Saving throws are still taken into account).
  
• Not only do you gain health from walking in blood from the Leech ability, but you also gain health from each hit you take from physical attacks. Blood is soaked up and disappears the moment it's touched with this ability.
  
• Resting in a bed heals your characters.
  
• Item rarity is White<Blue<Green<Orange.
  
• You can create waypoints and write messages to them in the map for you and your co-op partner to see.
  
• Holding down ctrl is a good way of shooting ranged attacks through smoke and fog.
  
• Anything that happens in a building, stays in a building. Killing or stealing in a house will only alert people within that house.
  
• Healing skills damage zombies.

• Can't play with more than 2 players co-op.
  
• Can't dual wield weapons.
  
• No hotkeys for switching through the skillbar.
  
• Can't take characters from one game to another.
  
• Can't grind xp.
