In Wizardry Online, there are a lot of different objects that you will need to interact with. Interacting with an object usually involves getting close to it and hitting the F key on your keyboard or clicking the F button that pops up on the screen. There may then be additional ways to use the object after that.
To open a door that's blocking your path, go to the door and then press the F key on your keyboard. If it's a double door, you'll need to hit the f key, then either hold down the W key on your keyboard to open the door, or hold down the S key to close the door.
Treasure Chests Edit
Treasure chests can be found in dungeon areas. This is another object that has an interaction. To use it, get up to it and click F on your keyboard or click the F on the screen.
However, some treasure chests may be rigged with traps. Use disarming skills on armed treasure chests to increase your chances of successfully disabling it. You can also attempt to determine the type of trap. Note: you might not always be correct if you lack in skill.
If you succeed at disarming the trap, you can take what's inside. If you fail, you'll trigger the trap, this may lead to your death and/or someone stealing your chest loot.
To use a ladder, hit F on your keyboard or click it on the screen. Press W to move up and S to move down. If you need to get off the ladder at any time, click F again. Droping from mid ladder may cause fall damage.
