Wild Card is just that, a wild card. You can use the known and trusted Ender IO to process your ores or you could try Embers. There is no one way to perform a certain task in this pack. The choice is yours.
With Level Up you can enhance everyday task in a semi-RPG fashion, increase your defense to fend off the "special" mobs that randomly spawn due to Infernal Mobs. Or just max out your damage to end your foes swiftly.
Harvest ores from the void of the world with environmental tech or a Quantum Quarry from Extra Utilities. Or you can plant and grow most resources with Mystical Agriculture.
With Wild Card the choice is yours.
