Using Your Demigod
If you've ever played an RTS game before then the controls in Demigod will be very familiar to you. Use the right-mouse-button to tell your demigod to move somewhere, or if you click on an enemy unit, demigod, or structure then he'll engage and attack them. To use abilities, you have two choices. Either click the skill's icon in the left side of the UI (slow) or simply press the hot-key associated with that skill (fast). The respective hot-keys of each skill are shown at the bottom of their icon. For example, Structural Transfer as shown below has a hot-key of W. You'll find that all skills in the game are mapped to Q, W, E, and R for easy access.
You can use items in a similar way. Either click their icon on the right side of the UI (again, slow) or press their hot-key. The hot-keys for your three items are F1, F2 and F3.
Capturing the Center Flag
The first thing you should do once you've got all your equipment and items is go to capture the middle flag.
To capture the flag, simply stand next to it. A small bar will appear that shows how captured the flag is. Once the capture indicator moves into the small white area, you've captured it, and you'll gain 50 experience points, which is enough to level you up at the start of the game.
While the AI may let you capture the flag uncontested, human players will not be so generous. It would be a good idea to ask you team mates to come with you to make sure that
you get the flag and no one else. Of course, once you get it, you'll need to keep your eye on it to make sure they don't take it back.
In addition to the bonus experience, holding the centre flag gives you an increased war rank by one. Your war rank determines what level of units spawn from your base. Not every level gives you new units, but holding the middle flag can mean the difference between having giants fight for you, or having to fight against them.
Assist Your Creeps
Once the centre flag has been captured, it's time to start assisting your creeps in battle. At the start of the game, most battles will happen in the middle of the outside lanes, between one of your Towers of Light and one of the opponent's Towers of Light. You should head there and start beating up enemy units to gain experience.
As you can see, The Rook -- being so big -- can often block your view of enemy units. Being the sadists we are, we like to see our enemies being crushed into the ground. To rotate the camera, hold down the space-bar and move the mouse.
Much better!
When fighting against enemy units and demigods, it's usually better to kill off the units first, then focus on the demigods on their own. The most important thing to remember is that you should never fight a battle where you are outnumbered. If the opponent has more units or more demigods than you then retreat back to your Tower of Light. Fighting a losing battle is never a good idea.
That being said, it's unavoidable that you will be attacked, and you will often run low on health and will need to return home to regenerate. The best way to do this is to use a Scroll of Teleporting. They only cost $100, and allow you to return back to your healing crystal in a matter of seconds. You should always have one on hand.
To use the scroll, click its icon or press its hot-key then left click on an allied structure (such as your shops at home). A yellow progress bar will appear, and once it fills up you will instantly teleport to the structure you selected. Beware though: stun and freeze spells can interrupt your teleporting; if they hit you before the progress bar fills, you will be stunned and will have to reuse it once you are un-stunned. If you are playing against opponents that have stun abilities then you'll need to be extra cautious when using the Teleporting Scrolls.
One good strategy is to try and stay alive until you have enough money to purchase something from the shops. This way, you can teleport back to heal, and you can buy the equipment while you're there, saving you the extra journey. Being efficient with your time is an incredibly important skill in Demigod.
Another important skill (if you can call it that) is knowing what items are best to buy. One particularly good piece of equipment is the Pantheon's Blessing, which costs $4200 to increase your health by 950 and health regen by 0.9hp/sec. The massive health boost is especially useful for weak characters like The Torch Bearer and Regulus. The Rook on the other hand may want to get armor instead, to improve the quality of his hit points rather than the quantity.
