Game manual
Moving and fighting
You walk with the arrow keys or by clicking the ground. To attack, click the creature. Combat runs in short continuous turns: stop thinking and you take damage.
Items and backpack
Everything has weight. The backpack fills up, and what does not fit stays behind. The town depot holds what you do not want to carry.
Death
Dying costs experience, and can cost items. You can reduce the loss with blessings, bought from the priests in the towns.
Useful commands
The full list is on the commands page.
Rules
The server rules are on the rules page. Worth reading before, not after.
