Out of character:
Since we are only first level, What do we know about Trolls?
Specifically about regeneration and about using fire or acid to permanently destroy them.
Including an intelligence roll if appropriate.
In Greyhawk, characters have general knowledge of monsters and their abilities. Especially the more common creatures. Trolls would be one of them.
I created a character and put the info in the sheet. I decided on a rogue, his name is Thane and he will play as a rebellious dishonorably discharged soldier who is willing to risk his life for gold.
Don't have the rule books, I used the Dungeons & Dragons 2.0 Next button which I'm guessing now is not the same version. I noticed the attributes / feats resembled latter versions but if I took those out it would work for your game?
I think I have what you are looking for now and updated my character sheet. I did not buy anything yet because I don't know how much gold I had or what was available. Do I already have thieves tools or do I have to buy it?
Okay, this looks good. Just a couple of things though, you start with max HP for 1st level which for a rogue should be 6 (Don't have my books with me).
You can start out with 80 gp of equipment, and you have to purchase your thieves tools. Any standard equipment is available.
I had to budget a lot after buying the thieves' picks but I think I have all that I need now. I also got myself a guardian and chose a symbol etc.
