Because the previous thread gets long, I have decided to make a new one and add some FAQ:
What is the Grail?
Grail is a collection of all unique and set items in the game. We don't collect runes here. We have a self-found grail and grail with traded items included.
In wider meaning it could be a goal you have set for yourself.
The ethereal Grail thread is here.
The Perfect Grail thread is here. (edited by Hrus 02-JAN-07)
How much items is it?
504 items total, 377 uniques, 127 sets. For 1.09/1.10 it is one item more - unique Crystal Sword Azurwrath (This no longer drops in 1.10). We count each type of Rainbow facet as a different item.
How should I keep track of my grail?
There is an excel spreadsheet called Medieval Mart. You can download it here . It computes number of items left automatically if you just enter 1 before each item you have found. (I have changed my local copy of Medieval mart, so it doesn't count the runes.)
Another wonderful tool is Flavie. Check the sticky at SPF for more info.
How should I add myself to/update current tables?
The code tables editing is tricky sometimes. Hit the reply button at the last post with tables, remove quote tags and comment of the previous poster. Edit the appropriate table and add your own comment. Use the Preview post button and check if the table is right. Then submit your post.
There is no rule here when 2 or more players have the same total numbers of items left. IMHO there is no honor to add yourself above the other player if you are only tied with him.
Any other rules?
Yes, you have to use vanilla D2. That means no hacked or duped items, no drop-mods, no items you are not sure of their origin! If you use an Enigma with duped runes, you can't be honored to complete the grail quest! (And with that is said, all B-netters are out until they start a single player carrier ) You should also have the items physically in your stashes/characters.
EDIT: SPF accepted mods as RRM and RWM (or combination) are accepted, just specify them in "Type" column.
