New Player Excalibur Build No Orokin Reactor, Mods From Earth, Venus, Mercury, Mars, Phobos, and Nightwave.

Polarities: If the symbol on the mod is the same as the symbol in the slot, it doubles for aura or halves for regular mods. (Example Flow and Continuity being half its normal cost, and Steel Charge being double) if a mod is of a different polarity it takes more capacity.

Aura: This Mod Slot is the only slot that is good to put a mod in regardless of the mod itself, It increases your capacity by the mods displayed amount in the top right corner. Good Choices from Nightwave: Steel Charge (18 extra capacity), pistol, rifle, Shotgun Amp (14 capacity) (Only 5 Extra Capacity equip Energy Siphon or Corrosive Projection)
