Lets see if I can remember....
Bastard Sword-Knight south of SF castle. Not bad, about 70-80 avg damage. 2 handed.
Singing blade-Ars magicania sewers. can get up to 100 avg in damage, possible frost etc. pretty good. The fight is fairly tough, but doable. 2 handed.
Blade of Chaos-cave east of dwarf village, on raised ground. Again, damage around 70-80 avg. Abilities can be better than the bastard sword as this is a gold item. 2 handed.
Royal sword-This is good early on in the game. Can be bought/nicked from the blacksmith in Ars. Dmg around 50 avg. 2-handed.
Deathknight Sword-Pero the armour dealer in Ars(e) magicana. Can be bought/stolen if you're clever. Possibly as good as the singing blade but not usually.
Nobleman's sword-Quest item. Good one-hander as shields count in this game. Keep re-loading to get good damage etc. Damage can be in the 70-100 region.
Sword of the gods-wastelands item. Can be better than the Nobleman's but you have to wait a while to get it. 1-handed also.
Scary avatar BTW. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
i have rescued 6 of the seven council members and i am using the deathknight sword and i like it alot....but the sword in the stone and bastard sword from the knight are both very good as well....
