The first part of the Underdark portion of my D&D 3.5 Roll20 campaign has been completed, with the party well out of D1 Descent Into the Depths of the Earth and rapidly approaching D2 Shrine of the Kuo-Toa. To mark this occasion, I've uploaded some of the maps that I've used recently to the campaign page.
Since the party has now reached 25th level, we're beginning (some might say we started a long time ago) to push the limits of the D&D game system. The Epic rules make normal adventuring really difficult, and given that the campaign was based around simple dungeon bashes this is making things hard. Whilst it may be suited to taking on single large creatures of high CR, the imbalance becomes very obvious when the adventure is in a small Drow settlement where even making a few NPCs level 20 doesn't make a lot of sense.
Part of the problem has probably also come down to the easy availability of magic items. A long time ago (about 2 years and about 20 levels or so) I decided that this was just going to be a simple sequence of dungeon bashes to try out playing in Roll20, and all downtime was abstracted to the point where any magic item could be purchased as long as the PC had the cash, and the item was within the GP limit of the town they were based out of. This does allow PCs to build highly optimised characters.
At this point I've decided to try and bring things to a close relatively quickly. We still have D2 and D3 to complete, as well as Q1 (which will probably be better suited for Epic play), but I'm not going to stretch it out any further than I have to.
However, it has given me an opportunity to finally use many of the books I bought but never used for d20, and I'm even using adventures I bought back in the early '80s for 1st edition and using them for the first (and probably last) time.
