Are these limited to 1 per account?

Yes, you can potentially get 3 per account if you started as human and have gotten a Elf and Giant assistant cards. Course there's people with around...10~15 playable characters on the account.

But come on, who trains alts? I have alts that are, at the least, capable of self-defense and essentials. Personal opinion, I'd rather see this limited 1 per account for the whistle...too many AoE Perseuses...is that even the right term D:...

Same... 1 per char was too much.

Why would anyone even need 10? I saw a guy during the Treasure box event with 10...people are strange...I'm fine with my 1 Lv62 Perseus...

10 is like 4k damage/minute though. :L

I can see someone getting an army of Pegasi just for the inventory space.
