NOTE: you have 5 cards in your Sylladex now, right? So you can basically carry 5 things in your "inventory" without feeling their weight or anything. But if you were to captchalogue a pink card and then alchemize it... You don't have to merge stuff in order to alchemize, you see. If you want to duplicate something, you can just scan the sylladex card alone and alchemize the item. What I mean is, you can create more pink cards if you want to be able to carry more than 5 things in your Sylladex.
There's no need to duplicate green cards though. You can store as many different kinds of your special STRIFEKIND as you feel like in your "green wallet". At a certain point (at a certain level) you will be able to get an additional STRIFEKIND. Before that, Vieve is restricted to fighting with AXEKIND, Candice with BATKIND, Vinnie with SWORDKIND... and Ricardo hasn't chosen yet, has he?
I'm probably going to go with REVOLVERKIND. That, or LASSOKIND (since he has trained charrerías according to his history…)
Also, WATER WORLD! Yay! It actually reminds me of one of the planets I pitched you a couple of pages back, so needless to say, I'm looking forward to it. :D
