Dvergr Mage has 350 health and spawns in the Mistlands.
It resists fire and frost; spirit does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.
Its hardest hit is dverger staff ice icebolt at 200 frost, out of 7 attacks.
Some of what it throws is elemental, so fire and frost resistance is worth having.
Of everything craftable, 
Thunderblood Crossbow, 
Lightning Strike and 
Frostfire Crossbow put the most damage through what it resists.
It always drops 
Coins.
Dvergr Mage is a neutral Dvergr faction caster stationed at Mistlands excavations, guard towers, harbours and lighthouses, up to four to a site. It has 350 health, resists fire and frost, is immune to spirit, and runs at 4 where a 
Dvergr Rogue runs at 7, so it rarely chases far. Each one belongs to one of three schools, red for fire, blue for ice and green for support, and the two battle schools keep a 70 blunt staff bash for anything that closes. Drops are 2 to 15 Coins, 
Black Marble at 50%, 
Soft Tissue at 25% and the 
Dvergr Trophy at 5%.
Do not group up: the fire school's clusterbomb punishes formations and the ice bolts hit for 200 frost a piece. Break line of sight between casts and take them one robe at a time. They resist both fire and frost, so plain physical damage or spirit does the honest work.
With devcommands enabled, this spawns Dvergr Mage in front of you. The third number is the level: 3 spawns a 2-star.
