That's what it all comes down to: combat in the realm. If you don't know how to handle yourself when besieged by monsters, you will die before you even make it through the week. If you are smart and/or lucky enough to have hirelings, you may be able to survive even longer, especially if you know how to use them. In a recent discussion on the Magic Realm mail group (see http://wolff.to/mr/ for joining information), the strategy behind luring and deploying was dissected, and I thought it would be worth bringing forth here.
The luring stage comes before the deploy stage, and the end result is similar: your hireling is battling a monster on a separate combat sheet. What really differentiates these two actions, is what happens during battle resolution. A hireling that lures a denizen, gets to choose its side and position and will not be affected by random placement or changing tactics. This can be very important if your hireling has a definite power attack on one side. The most dramatic example of this is an archer, who has no attack on one side, and a speed 1 attack on the other. If you lure with an archer, you are guaranteed to at least undercut the lured opponent, and score a hit. If you deploy an archer, you lose that control, and the archer even has a chance to "change tactics" (ie., flip) and become virtually worthless for one round of combat.
Why then would you ever deploy? Where luring only allows a hireling to bring one denizen onto his sheet, deploying enables you to pile your hirelings onto a denizen's sheet, and better your chances of getting the kill. It's true that you cannot guarantee where they will end up during battle resolution, or even which side they will be on, but the numbers are in your favor. Remember that when you deploy, the LAST attacker on the denizen sheet, is the TARGET of that denizen.
If you are playing by yourself, this enables you great control over how the hirelings will lay out on the sheet, and lets you choose which hapless hireling will be the target. However, playing with multiple people can definitely mess things up a bit. You might lure with your archer, assuring a kill, but then lose the advantage when another player deploys his hireling assassin to your target. What happens in this case? The target moves to its own sheet, with the assassin as the first attacker. The luring archer is now added as the second attacker, and the target of the denizen. Not only is your archer a target of the original lured denizen, but his position and tactics are randomized, limiting its effectiveness! (Thanks Vincent for pointing this out!)
If you are confused about the comings and goings of luring and deployment, this example (provided by Vincent on the discussion group) does a good job of bringing it all together:
- A lures monster
- Monster moves to A's sheet, A is the defender.
- B is deployed against monster
- Monster moves to its own sheet with B as the target
- A is now alone, so A moves to Monster's sheet
- Monster switches to targeting A since A was the last to enter his sheet.
- Monster moves to its own sheet with B as the target
- C is deployed against monster
- Monster targets C since C was the last to enter his sheet.
In summary, lure when you want to have control over your hireling, deploy when you want multiple attackers against a single denizen. When playing with others, watch out for luring/deployment combinations that might change your battle plans.
Update - I just got this note from Steve M:
But there is another obvious reason to deploy rather than lure. You can only lure unhired denizens. If you want to attack a character or another hired denizen with your hired Rogue, you've got to deploy!
