If you are using blast mining on an ore patch with multiple ore bundles, the explosion affects every ore bundle, allowing you to mine multiple bundles out in one blast.
* Example: If you detonate a small C4 charge with Basic skill Skilled level in Mining and roll 35 limb damage, the skill level allows you to multiply the result by 2, for 70 damage. 70 damage is enough to mine out 3 ore bundles and damage a fourth one by 10 HP.
