Well, it's my third time through this game, but I have yet to get the trader card from Hammer. I am currently at that point in the game, and I can't seem to get the Trader Card. I thought that you were supposed to equip and Ether Doubler on Elly and use Aerods to cause 9999 damage. However, I have an Ether Doubler equiped on Elly and my Aerods do zero damage. (Both when he is glowing red, and when he is not glowing red). Am I missing something, or am I using the wrong strategy?

Also, I have tried using Fenrir and Crescens and have them get thier Infinity mode, but they don't seem to get it when I need it. Is there a way to go about getting infinity mode easier for gears other than Welltall 2?

Any tips on getting the trader card would be much appreciated. Thanks.
