This is a public Google Docs/Sheets based AD&D 2E Character Sheet I put together for some recent adventuring I did with old friends. It's pretty simple, but also very flexible. The sheet's got spell and thief sections that can be expanded upon or nixed depending on the character class/kit/race/etc.
There are definitely some updates and additions that could be made. My DM and I created a dozen+ characters for a long weekend of adventuring and this template worked great.
If you make any big updates, let me know so I can add them!
