European Standards and CE Marking. Prior to exporting, U.S. manufacturers have to consider certification for the EU market. Certification is about conformity assessment (testing and certification) in order to declare compliance with EU regulatory requirements. For the majority of exported products, compliance is visibly testified by the use of CE marking. Use of standards is part of the process. Bearing in mind that testing and certification for the U.S. market are not sufficient for exporting to the EU, manufacturers will need to start from scratch in order to determine what it takes to comply with EU requirements.
Energy Conversion is a Warframe mod that increases Power Strength for the next ability cast after picking up an energy orb.
Warframe however also have an Aura slot and if an aura is equipped it will increase the maximum mod capacity. Depending on the rank of the Aura and the polarity of the slot this can boost maximum mod capacity from anywhere between 0 (if no aura is equipped) and 14 (if an aura is maxed rank and the polarity matches). On the subject of polarities some weapons/sentinels/warframe come with polarities (markings on the mod slot). When a mod is equipped and the polarities match, the cost of equipping said mod is reduced by 50% (rounded up). When the polarities do not match the cost is increased by 25%. For Auras the point boost is doubled if the polarities match and reduced by 25% if the polarities are different. You can add any polarity you want to any mod slot of your choice by using the forma item. This resets the rank of the weapon and you will have to re-rank the weapon.
