To do the sword in the stone thingy, exactly where do I get the blood stones..

There are 11 bloodstones 1 from each lvl which help get the last extra level, but to get the extra levels you need to beat the little games that give you experience which are nest to the picture of the plain, your at level 21, I only have 1 bloodstone and I'm lvl 33 I found it hard cause I lost 1 before, get all 11 bloodstones from the levels and try beat all the lillte games and extra levels they give experience and money, the plain of war you need to beat 4 horsmen using no potions to get champions medal, I am level 33 Dark elf, disease bolt and summon skeleton helped
They easy if you range rather than full on attack when you finished and you won the medel you get 2 points for your spells and experience I think money but yea pretty explanitary, all levels have different things in them and they get harder hope this helps but I only been playing for 2 months I'm still learning most of it

There are eleven bloodstones you need. They are the Bloodstones of War, Innovation, Water, Torment, Disease, Valor, Fire, Storms & Nightmares and are each lcoated in their respective Plane's bonus round. The Bloodstone of Isles is located in the Gothic Castle (sublevel of the Pit of Ill Omen) and the Bloodstone of Faydark is located in the Orc Caves, a sublevel of Faydark. Be sure to search everywhere and break everything when in these rounds as the bloodstone could be hidden just about anywhere. Note, you'll also need the Words of Spiritual Harmony from the next level after Faydark (Plane of Nightmares - the Words could be anywhere in that plane) in order to finish searching the Orc Caves and retrieve the Bloodstone of Faydark. Also note if you're playing the evil side the Bloodstone of Faydark could be anywhere in the Faydark (the caves, the forest, or Kelethin).
