Honour, Hope, Love
If you're ever leaning towards INT with any intention to cast spells, either of the Bloodmages are fantastic choices. It helps that they're both FO armours as well, so you can hack away at will.
If you're looking for something 'here and now', Call Dunamis is great. He gives a flat 38% damage boost to melee attacks. I'm not too big a fan of spending GGBs on weapons, considering that that the available equipment in the game is generally sufficient.
Void of Nulgath is apparently good combined with the Zealot weapons, but there are too many FO Darkness Armours as it is.
