Which kind of melee weapon do you love most: one-handed or two-handed weapon?
Which kind of build do you make & love most ?
How far in the game are you, which level ?
and a tip :
Is your Strength higher than your Intelligence (go for melee damage based weapons) or vise versa (go for magic damage based weapons), or around the same value? (go for balanced weapons)
I find the "Sword of the Paladin" (two-handed!) a nice piece . But the Scorpion Sword (of the Scorpion Armour Set!) is also nice !
I'm now in the Flames of Vengeance part and the shopkeepers there also have nice melee weapons ... but the most nice weapons require a level (L35 - 36 - 37 and higher!), so then you must wait, so best to go for better weapon earlier on if you find the Razakel's Warhammer isn't good enough anymore

...
And since you've the Battle Tower and your runners (servants) Gold isn't an issue anymore, so sell and buy if you wish/can for a weapon that suits your playstyle best, let the goldcions roll like a dice

!
I started Flames of Vengeance with more than 200 000 goldcoins, but starting with 100 000 or something I've still enough, in fact.
