Creating a really shitty vampire is easy. It is done every day in every dark corner of SL you can think of. Here, I will give you all the necessary rules to making this happen. Note: This also applies to shitty lycans and shitty blood dolls.
Rule Number One: Get Flashy.
You need to be noticed, so go ahead and make yourself look good. Now, if you think your chances are best looking scary as hell, do it. If you think it would be best if you looked super sexy, put on that thong and make it work girl. (or guy, to each his own.) Looking good is half the attraction. If you can attract them, you will most likely win their heart.
Exception to Rule Number One: The trick bite.
If you don't care about having any kind of communication with your prey, then dont even worry about how you look. If your game is just randomly biting tons of people in hopes that one or two will eventually buy the HUD, then leeching is your game, and don't even worry about looking good. Though, it may still help. Especially in notorious sex areas filled with hot and half naked avi's.
Rule Number Two: Make Promises.
Making promises is a great way to reel them in. (If you want to create a good vamp, making promises that are REAL does help, as long as they are real benefits to joining). What kind of promises can you make? Oh, the possibilities are endless! Here are a few examples:
"If you join us, we can make you royalty"-Now, this isn't necessarily false, but they will have no idea how hard it is to become royalty, sneaky ay?
"I'm single you know, and I really like you"-This creates a false sense of attraction to their personality. The unsuspecting victim will surely fall for your trap, in hopes that they can have a relationship with you, especially if they see you as some sort of Edward Cullen. (Thats another good idea, talk about Twilight A LOT if you're a guy talking to ladies. They might see you sparkle and fall for it!)
"I know everyone in the clan, I will make sure you're comfortable."-This is another one that very well could be true. But usually isn't. Especially if their clan in heavy in numbers. This particular promise will be addressed in a later rule. This promise will make them feel like they are going to be ushered into the clan with some sort of parade, like they are a new born or something.
"We can probably find you a BF/GF in the clan"-You're not a match maker, but you can pretend to be one, especially if this avi seems particularly lonely or in need of a companion. These avi's can be easily spotted, just check out their profile. Any group relating to a dance club, dating service, sex service, etc. can tip you off. Little do they know that you don't actually intend on finding someone for them.
Rule Number Three: Flash that $599L.
Make sure they know that you are doing them a GREAT favor by paying for their HUD. Drop that 599 number a few times, it will make them feel like they are worth it. And they are, well, their soul is, you could care less about their personality. Try to make them feel bad if at all possible that your spending this money on them, it will sucker them in even more.
Rule Number Four: Turn them fast.
Don't give them time to think about it. If you do, they may get smart and look you up, or your clan. You also don't want to give them time to make a big decision. They can regret it later, but you will still have their soul.
Rule Number Five: Give them a heartless introduction, if any, to the clan.
By all means, don't create a notice to the clan introducing them. If you can help it, don't even introduce them over clan chat. The best way to keep them from bothering you is to not introduce them to anyone at all, especially clan royalty. Let them do this on their own, cause they most likely wont.
Rule Number Six: Leave them all sorts of confused.
This is the most important rule. If you don't use any of the rules listed above, ALWAYS use this one. Don't explain a thing to them. Once they have turned, make up some excuse to leave. Don't tell them to read the rules, TOS, NC's in the crate, any of it. The only thing you should do, is tell them to wear the fangs and teach them how to bite. But don't tell them not to go out and random bite, tell them to bite anyone and everyone, anywhere. An educated vampire will only give you grief. Keep them as dumb as possible, then they will be solely dependent you.
Those are the rules. Go out and make some shitty vamps! Why? cause its fun and then you can rank! Remember, only think about number one, and you surely will be prosperous in Bloodlines.
