Runeword bonus stack with magic bonus?

[Sarp]

Simple question. If I find a magic wand, socket it, then put a runeword (White) for instance, do the runeword bonuses stack with the old magic bonuses of the wand? I.e. if the wand had 20% FCR and White adds 20% FCR do I then get 40% FCR?

You can't make a runeword into a magic item.

[Raskah]

No, you can't.
Runeword can't be created in magic, rare, set or unique items. Just grey items...

They do work in ethereal and superior items though, but not in magic/rare/set/crafted/unique items.

However, if you find a non-magic wand with staffmods (+skills, that are on white/gray items) such as for instance +2 Bone Spear, and make a "White" runeword in such a wand, you will get both the staffmod bonus and the runeword bonus (ie. total +4 Bone Spear and +3 Poison & Bone skills).

Last ladder, I had a sweet "leaf" runeword in a grey staff which twinked any sorc early on (more so if she ended up being a fire sorc). It had +3 to fireball and +1 to warmth, and with leaf, I think it made it so I had +6 to fireball, +7 to warmth, +6 to a few other skills, and +3 tio the rest of the fireskills. I was proud of that one, even once I outgrew it.
