I normally run my campaign very tight on available races. PHB is just about it. The PC's in my campaigns over the past 5 years have gotten used to it and don't even ask to play anything "unusual". The Savage tide campaign has gotten me interested in doing something unusual. I was a bit concerned about PC deaths when the party was out in the jungles unsupported and came up with this twist:
The only races allowed are:
Olman (native)- Human with a -2 int +2 wis, preferred class cleric (they are very spiritual), with only access to wooden, bone, or stone equipment.
Arenea (preferred class Sorc)
Lizardman (preferred class Barbarian)
Phanaton (preferred class rogue)
Rakasta (preferred class ranger)
I expect that it will be an interesting change of pace for them for a while.
...Olman (native)- Human with a -2 int +2 wis, preferred class cleric (they are very spiritual), with only access to wooden, bone, or stone equipment....
Just my two cents: I think -2 Int is inconsistent with the fairly advanced culture they've had in the past. I think the same idea has been put forward by others on another thread.
