How much we need to LB3 Orlandeu? I read the information in this site but it seems we can only purchase 120 + 20 shards as event rewards.
How we can reach 240 shards? Should we waste our visiores by pulling the banner hoping to get multiple orlandeu and then redeem the mog shop's medal to get more?
Yes, you can only buy 120 in the FFT Collaboration Shop. No, you can actually buy 80 with FFT Event Medals.
The other 40 you can get by:
A) Buying them in the Shop for visiore (regular, you can reset once daily for free), also appears in Wimsy Shop and maybe in the Lightning Unit Training Items Shop;
B) Summoning 1 dupe;
C) Buying them in the FFT Summon Medals (B) shop, for 5 shards per 2k summon.
Best way to max him out at F2P is to reroll till you got him from the first free summon. Then you can use free visiroes to by 2x40 pack. Then you can farm the even to get another 80. Then you have 400 more shard which you can buy from shop when he shows up. It will cost you 20000 viriores but you will get them all from quest, gift and events for sure
