This addon adds in a Faerie, or Fey, race into ToME. This addon was originally created by Kaballah, but he hasn't been online in over a year.
Instead of letting it die (I mean, how could we not be able to play as a Faerie?) I decided to fork it over into a playable form.
I've taken it, modified it's values, and changed it's 4th talent.
You can nab it here.

Dark Faeries are Faeries that have given up much of their natural agility and defense in exchange for bonus offensive potency.
They are extremely frail, even more so than their more agile counterparts, but make up for it with faster offense, higher damage, and many different tricks.
Despite all thoughts otherwise, they are still, mostly, a playful bunch to be around, if not a bit more painful in their method of invitation.

Adds a new game option "Short-circuit some early dungeons" to enable or disable the new b43 behavior of skipping the player directly to the bottom of tier-1 dungeons if you're strong enough. The option will appear under Game Options in the <Esc> menu.

Also available as part of the ZOmnibus Addon Pack and ZOmnibus Lite.

Adds Beholders as a playable race. Created by ajfluffy (design, code and conception) and rexorcorum (ideas and artwork), this addon is now being maintained by Nagyhal under the guidance of rexorcorum in ajfluffy's absence.

Edit: Had to change the addon's short_name, and so v1.0.6's automatic upload helpfully made us a completely new addon page. Of course it's all on Steam, which is beautiful (thank you DG!), but I'm hoping we can merge the older versions into this thread. We'll look at it tomorrow.

Edit of the edit: In the meantime, players who have fallen afoul of my clumsy Flame Laser bug are encouraged to upgrade to v5.9.2 for compatibility reasons. Have fun and happy facemelting!
