Mike Mearls’ Combat Maneuvers

Yesterday I mentioned the manoever system from Book of Iron Might. Mike Mearls, who later went on to design Dungeons & Dragons 4th edition, wrote this mechanically interesting expansion for D&D 3.5 in 2004.

The maneuver system (I’ll use the American spelling to stay consistent with the book, as it’s a game term) allows you to perform a wide range of combat techniques without taking a feat, but at the cost of a large attack penalty of -10 or greater. This penalty can be offset by taking drawbacks.

Lets say you wish to knock an opponent prone. You can do so, at the impossibly high penalty of -20 to attack. However, you can reduce that penalty by 10 if the maneuver provokes an attack of opportunity, by a further 5 if your opponent gets a saving throw or opposed check, and another 5 if the attack only knocks prone and doesn’t deal damage.

Other possible maneuver perks include disarm, bonus damage, ability score damage (2 points), blindness (1d4 rounds), speed reduction, daze, stun, and disabling a natural attack or special ability such as the beholder’s antimagic eye.

This deconstruction of the 3e combat system is what got me to first take note of Mike Mearls and his grasp on mechanics. His later work, the similarly titled Book of Iron Heroes, formed a lot of the groundwork for D&D 4th edition. I’ll write more about Iron Heroes in my next post.

If you’re interested, you can buy Book of Iron Might at RPGNow for £4.41 in PDF, £7.25 in print, or whatever that is in your currency, which looks like Monopoly money to me.
