Yeah, Nezmod has lots of rigged items and charms. Look at the All are One charm! You get this by collecting 18 dolls
. This gives you +3 all skills, 20% more damage to all elemental skills, thorns damage of 27, 30% more exp, -5% to enemy resists, +X to all stats (per level O_O), and damage bonuses that give you like 650+ in elemental powers. Then again, you have to kill 18 bosses over and over to collect thier pieces. It was a pain in the ass to collect the first 6!
Also, unique items drop like crazy. I played Act 4 on Normal and I got a unique Long Sword, Battle Axe and Full Helm from various monsters and pots.
If you ask me, some rune words are good, but there are still uniques out there that have better uses. For instance, lets talk about necromancers.
If you have a poison necro, people think that Spirit is a good rune word for a sword (gives you +2 all skills). But you can get a Blackbog's sharp which adds 4-5 to all poison attack spells. To make up for it, you can add mana bonuses to it via sockets and runes.
But in some cases, runewords are better. For instance, if you use a Fire sorc: You can make Leaf out of a two socket staff (Tir + Ral). This gives you +3 Fire skills and other fire bonuses. Add that to +2-3Fireball or Metoer or Hydra, and you got yourself one deadly staff.
