No. In 2E, you can only have one type of mage armor active at a time, for starters. Additionally, these spells are completely different from the attainments in 2E, which aren't spells at all. Both of these 2E armors add to Defense, not actual armor. Mind makes the enemy hesitate and not want to fight. Space warps reality slightly to redirect attacks and allows you to apply Defense against firearms and even redirect them into other enemies (2E rulebook, p. 194 for both). I'm asking if the Mage Armor bonus to Defense is doubled when making a Dodge action in combat.

While actual bombs were made of clay so that they could actually explode (which would probably lower the cost by a solid deal, removing most of the metal), yes, this is exactly what I was thinking of! Thanks a bunch, mate!
