In their adventures, my PC's have met a Dragon named Goratrix, a huge dragon who loves to "play" (i.e wrestle ) with things/people and has a really joyus and happy personality along with his amazing destructive capability. "i.e. I'll do a favor for you, but it was to be something awesome like burning down the country side and eating everything in my path so those men with the metal who ride horses come play with me. Also not very bright.) One of my PC's is interested in getting him as a familiar.
Now, per RAW, the lab total needed would be 145. (25+5size+Might = 25+125+60=145) This kind of total could possibly be done with lots of studying and the right virtues, (namely, the right Major or Minor Magical Focus, lab assistants, but I'm wont to dissallow that, as the binding the familiar is a very intimate procedure that I'm not sure outsiders could help with) but would take so much time that it would be an end game possibility.
As an alternative, I can see 2:
1.) Doing some kind of original research into making the binding of familiars much easier, perhaps with added benefits.
2.) Doing some research into Legends to find some kind of plot device item that makes binding a familiar much easier.
My PC's absolutely love quests and would go gonzo over 2, and mayfind 1 really boring. (i.e. "no quest and just a bunch of dice rolls? Lame!) So, the question becomes, what the hell kind of item would they have to find? And if you have other suggestions about the whole situation, please let me know. I'm generally ok with my PC's doing crazy things as long as the stories are fun to SG and my players are having a great time. I don't like to dissallow things out of hand unless I know they will result in poor outcomes.
One other question, does binding a Magical Creature mean that the creature no longer has to live in an Aura for most of the year? (Magical Realms book)
Edited to add: Two of the other PC's have "Magical Animal Companion" Flaw for an Owl and a Cat. I'm not sure if they want to make them familiars or not.
