Mining - Gloria Victis

Lower tier materials are common everywhere, but in especially high concentrations closer to the capital cities and along roads. To mine, press E with a pickaxe equipped in front of a mineral node OR attack the node by swinging at it. Attacking the node uses stamina but is much faster. Pressing E is slower, but does not use any stamina.
