That allow you to choose different/extra class skills?

[Darmanicus]

The Human Paragon can choose several skills of its choice and it also allows one to be chosen regardless what class you play later called 'adaptive learning'.

Are there any other feats etc. out there that can do much the same thing?

 

[Quez The Lame]

The Able Learner feat from Races of Destiny reduces the cost for cross class skills to one skill point per rank, but does not raise the maximum ranks.

 

[Darmanicus]

Cheers Quez however that's just not gonna cut it.

 

[Camarath]

Try the old Cosmopalitan feat from FRCS it gives one skill as a class skill and +2 to that skill.

 

[Darmanicus]

Cheers C, that sounds a bit better.

Or just talk to your DM, justify why the skill should be in the class list for your character, give something else up, and voila. It is suggested in the PHB that this is all fine and good after all.

Cosmopolitan was updated in Players Guide to Faerun.

Now all it does is gives a +2 to bluff, gather info and sense motive checks.

The various apprentice feats in DMG 2 give 2 extra class skills. For example apprentice (spellcaster) gives use magic device and knowledge (pick one) as class skills.

There is also a feat in Unearthed Arcana that gives 2 additional class skills. I can't remember what its called, and from its context it may have been designed only for use in a non-standard game although it doesn't actually say this anywhere.

Heroes of Battle has

Guerrilla Warrior
Benefit: When you are wearing light or medium armor, reduce the armor check penalty of the armor by 1 (minimum 0).
Hide and Move Silently ranks cost 1 skill point, even if these skills are cross-class for you. The maximum number of ranks you can purchase in a cross-class skill remains the same.
Normal: If Hide and Move Silently are cross-class skills for you, each rank you purchase in those skills without having this feat cost 2 skill points.

And

Guerrilla Scout
Benefit: +1 initiative bonus.
Listen and Spot ranks cost 1 skill point, even if these skills are cross-class for you. The maximum number of ranks you can purchase in a cross-class skill remains the same.
Normal: If Listen and Spot are cross-class skills for you, each rank you purchase in those skills without having this feat cost 2 skill points.

Handy for getting into Rogue like Prestige Classes or if you took one level of Rogue, and want to keep improving those skill when you are a fighter with limited skill points. I think the initiative bonus of Guerrilla Scout is named but I can't recall what type it is. But doesn't remove the cross-class limit.

 

[Darmanicus]

Some nice additions there, especially that versatile feat, cheers Slimey!
