Early on, wandering encounters are your best source of cash. Try resting a lot very close to where you start the game.
Poking around a dragon's lair is an excellent way to get attacked. Unfortunately, most dragons know about something you need to win the game. Be careful!
You can have your maps saved to disk when you save the game! Select 'Save Maps' from the Options menu.
It is possible to store excess items. There are places to do so in Silvar and the Castle. Where? Good question...
Always keep a back-up save slot or two. You never know when you're going to get trapped somewhere, or forget your major artifact in a town somewhere.
When a PC in combat moves into another, they switch places.
Save wands with one charge left, and use recharge spells to give yourself an extra kill spell (or whatever) for your next dungeon.
If a fear spell doesn't work, the next one is much more likely to work. Similarly, 2 poison spells do more than twice the damage of one poison spell.
You don't have to look at a wall to see a secret door. Just walk into it. This goes for secret passages in cave walls as well.
Try blessing a character 3 times, and see how he/she does in combat.
At low levels, magic is much more powerful than hand-to-hand fighting. Try to get a mage with third level in Priest Spells and Mage Spells as soon as possible.
A character can equip two one-handed weapons. However, it causes a large penalty to hit. Save this trick for higher levels.
Try using weapon poison on arrows. It's an excellent way to kill those pesky enemy mages.
Hitting 'G' has you pick up all items nearby. You can't do this if a hostile monster is in sight.
Hitting capital 'M' or 'P' has you cast the same mage/priest spell you cast last time.
You can select spaces using the keypad. Hitting 'l' and, say, '4' on the keypad has you look at the next space to the west.
Buy each character a level or two of strength as soon as possible. When strength is below 4, there is a penalty on the health you gain at each level.
Can't find gold? There's plenty in the wandering encounters around where you start. Get a mage who can cast fireball and you can fight the combats very quickly.
Hitting '0' on the keyboard or '=' on the keypad brings up the party roster.
During combat, hitting 'z' or '0' on the keypad brings up the status screen of the active character. Hitting it again brings up that character's inventory.
