Duardin are dwarfs, squat but sturdy. Many are miners, some are engineers, They are slower than most armies, but they can take damage and then dish it out themselves.
Duardin do not have any magic users, what they have are runes inscribed in to the armour, weapons, and banners. In Age of Sigma these are seen in the special rules for banners. If you are facing many magi then taking the Runic icon for the front units, however the rear units like the thunderers may be better off with the clan banner.
Dwarfs are slow but tough. This means that if you need to capture objectives, don’t hesitate, run for the objective from your first turn. This may mean that you may reach the objective before the end of the battle and be the target for war machines, archers and all. Don’t be too bothered about this as the Dwarf’s toughness should allow you to shrug this damage off.
The Gunline Strategy
Duardun have a major advantage over most AoS armies and that they have easy access to hand guns and powerful war machines. These ranged weapons mean that you can form a defensive line and wait for the opposition to come to you, pelting them with lead stone and crossbow bolts as they approach.
When it comes to Duardun warmachines having an engineer to hand will improve the warmachines accuracy. Note that an engineer can be within 1 inch of several warmachines at the same time. Create a triangle of warmachines and place the engineer in the centre of them.
