Chapter tactics -
Flamecraft: Salamander models have the Feel No Pain (4+) special rule against Wounds caused by flamer weapons (as defined in Warhammer 40,000: The Rules). Furthermore, when using flamer weapons, Salamanders models can re-roll failed To Wound rolls and armor penetration rolls that do not result in glancing or penetrating hits.
Master Artisans: During army selection, each Salamanders character may upgrade one of his weapons (even one purchased as an upgrade, but not a Chapter Relic) to have the Master-crafted special rule.
The Forgefather: If Vulkan He'stan is your Warlord, all meltaguns, combi-meltas and multi-meltas fired by models in his Detachment have the Master-crafted special rule.
