So I assume the dark crusader and albino bats are the only ones currently in game? I don't want to spend plat just on a set that I only like the pet and not the gear and have had zero luck on the albino bats.

I am cool with the albino bats being hard to get, that makes them more special. However, I would like to see some more pets available either as drops or as purchases with plat/gold.

So what sort of pets would you like to see?

I would like a quest chain to get a Homunculus (think deformed mini-me) type of pet. Something like you visit and npc and they give a quest to go farm a dungeon for some material from that particular boss (mildly low drop rate), do that a few times with different bosses. Once you have all the components, the NPC uses your vampiric blood to create your Homunculus.
