I’m not going to get into detail about how it works since part of that will be going into the FAQ. This post is simply going to be about my experience and impressions of a few co-op battles with strangers and solo fighting.
Since I wasn’t that comfortable with playing with random people around the world — especially without learning the system first — my initial multiplayer battle was by myself. Rank 1 Ifrit went down pretty quickly but Hamshal took a bit longer. I blame that on the cards I had equipped.
After the two solo battles, I decided it was time to try joining a group. I was hoping to team up with the folks at the Facebook community but by the time I got around to logging into the game, most of them were off to bed. 😛
The first group of players were all right although 1 or 2 attacked the boss with weak abilities when the Break gauge was still up.
My next fight was a bust due to a connection error that kicked in. 😦 You can see a screenshot of that below. The error popped up again once more during another time. 
I’m convinced that the server isn’t all that stable because sometimes, you can see allies get hit with the problem too. Hopefully, Square Enix will fix things up soon so everyone can have fun without worrying if they are able to finish a battle or not.
Things I have learned so far:
- I thought we could solo with an AI party like in the demo gameplay examples shown in the Square Enix Presents streams. Turns out that isn’t the case. XD
- People like stickers. XD Yoroshiku gets thrown around a lot and almost every boss fight ended with at least one person saying thanks. ^^; I’m kind of jealous of the users that have the Record Keeper ones. I got one too from doing the gacha but I haven’t put it in my sticker deck as I’m still trying to figure out which ones I would most likely use.
. - Players will listen to requests! I’ve put “Please Break” and the one with the PuPus to use and have gotten satisfactory results. Or maybe I’m just lucky since someone at the FB group seems to having a rough time with people doing their own thing and not listening. ^^
. - The grind for materials to exchange for multiplayer cards and class change material cards is going to be annoying since you need multiples of spoils from certain bosses. Maybe SE will tweak this too so we won’t need as much.
. - Having a diverse party with players that understand their roles is amazing. There was one time where I was with 2 Attackers and 1 Breaker. (I was a Defender.) Maybe if the cards and/or card levels were a bit different, our fight wouldn’t have dragged on for so long. :E But I suppose part of the issue was also me not doing Element Drives like a Defender was supposed to do. (We got hammered hard by Rank 2 Ifrit.) I am a dumb Defender. 😦 I explain this dumbness in a following point.
). - It’s really important to anticipate when a Break is going to happen and also to pay attention what everyone else is inputting. Team work is fantastic!
. - It may be me but it seems rather difficult to tell if someone is debuffing an enemy. Is there another icon for that?
). - I’ve been using my Knight of the Round Table as my main job. It’s classified as a Defender. I actually didn’t know what this entailed. After reading up on it, I realized I was playing my role all wrong. ^^;;; I was always contributing like throwing in a debuff when needed, assisted in chipping down the Break gauge, and whaling on the boss once it was staggered. The thing is, those are not the primary actions of a Defender. ^^ I hope no one was annoyed with me not playing to the role. ._____.
. - I’ve seen players START a fight with more than 3 actions per turn. How does that happen? I’m stuck with a measly 2.
. - Cards that I’ve been ignoring and never use suddenly become useful in multiplayer. Ugh.
Overall, I think the design the multiplayer mode is pretty decent. I’m sure it’ll get better over time too.
Here are a few screencaps I took. :3

Really love the new multiplayer system. I have same question though,, how does everyone can do 3-8 command while me being only 2?
You can get more moves if you don’t use up all your turns each time as they carry over to the next round. But it’s puzzling to see people start with more turns. ^^~
Oh yeah, I remember when I died, I didn’t know what to do so I just watched the battle until I see the Phoenix down icon. And when I revived, the attack bar is full (like 7/7) maybe the theory is right
Your speed stat is low. Certain abilities will give the user haste (more actions). Try switching your weapon for one with higher speed, or picking a class that gets more actions if you don’t like the one you have. You can also ‘save’ an action ’til next turn. (So I ‘get’ 3 actions every turn and can ‘hold’ 4 [it says 3/4 above my health], so if I only use 2 actions one turn, it’ll say 1/4 at the end of the turn, and when I get my 3 actions, it’ll say 4/4 and I can use 4 that turn.)
What is worth farming the materials to exchange in the moogle shop?
Not sure yet. I’ve yet to read up on the ability cards and weapons but if you have any of the FFRK cards in your inventory, you can farm class change crystals. I’m still wonder if the books are ability cards or not. ^^
🙂 We should all have the tyro card. Hopefully eventually we can get 5*.
I max out the given “Deshi” card at day 2 but other will be kinda pain as most need 2-star quest drops. Even the weapon for Mage which is the only available one will need 3-star quest drop for 3-star weapon. Queueing as host will get double quest drops but it seems to take forever for ppl to join… While going to join other players host team seems so fast that almost 70% you will get kick out and will be filled by others. Wonder why it takes so long to search for others as host. I didn’t put player rank lvl very high. And not so low as other players with 5-star job will join and die within the battle.
I never set player level and there was only 1 time out of the 3 or 4 times I hosted where no one showed up. That was depressing. T___T
Everyone’s been working on the Deshi/Tyro card but I’ve been trying to get the damn level of my 3-star Knights of the Round to reach 35 so I can do the class change. Sadly, I’m 99% sure I don’t have enough to max out the 5-star version of it. Max ability 4-star is questionable too. 😦 Wish I were awesome enough to get the first tier event prizes for the billions of Revival Tickets.
Only thing I hate about multiplayer are the afkers, scrubs and trollers. Had a couple games where the host starts the match and in the battle, he goes asked for the rest of the game. Also with the scrubs/trolls not sure if the dude didn’t know or was trolling but he kept healing the boss when we were killing it by using same attribute cards as the boss. Really passes me off because he did it the entire raid and we lost because of that.
