EaSy way to get Demonbrandt
I got the Demonbrandt basically as soon as i could beat that red-eyed soldier on the bridge (which was about soul level 10)
first, find the crossbow (or get a bow later in the game), and buy lots of bolts/arrows, or get some magic (of you don't start out with it in the first place). Now find a thief's ring (which you can find on the platform where you first meet Ostrava, or if you kill patches) and then kill Ostrava (or wait till world 1-4) for the Mausoleum key.
next, go to the mausoleum and kill the red-eyed soldier and open the door, and now make sure you have a LOT of time. (and make sure you have a thief's ring equipped)
target Doran, and shoot him with either a bow or magic, and when he comes towards you RUN AWAAAAYY!! to the bridge (you dont even have to pass half way), and when he starts to walk back to his first position, run up to him and give a good stab to the back, and run away again.
just repeat this over, and over again and soon (when about not even a third of his health is down) he will say that he is impressed or something and you can go get the Demonbrandt without him attacking you.
yaay you now have a really powerful weapon early on which will make things so much easier for beginners ^-^
EaSiest Way to Amass Souls Quickly in this game
First more then likely you'll have to beat NG and NG+ for this but it is worth it
First time you beat the game make sure you do the good ending meaning don't kill the maiden in black just leave the old one
Next after the credits you should get The Maiden in Black Soul -important-
After going through the game save Biorr and then from the official get the bloody Key Ring
After you have the key go save Yuria the witch see teaches you the Magic Soul Sucker
After you've done that beat the game again in NG+ by this time attacking the witch and becoming a demon for the old one
You at the point after the credits should recieve the beast soul worth 200k and the (Red Eye Stone)- Challenges a player instead of invade works like blue eye stone but your a black phantom
Now all you have to do is equip Soul Sucker and have someone you trust Soul *** you or the other only 1 person can go at a time
After that person finishes
-IMPORTANT- The person who got soul sucked must quit the game or turn off ps3 that way the lvl doesnt change (sometimes you may lose a lvl but in long run easiest way to lvl.
Also remember there is no thing as a legit lvl 712
