Subraces...

[Kendrac]

Is it possible to implement the ability modifications for the subraces in such a way that you can take advantage of the bonuses they should give? Examples would be the top spell level a caster has with INT/WIS/CHA increases and the amount of skill points earned per level with INT increase.
Also I play an assassin and the darkness spell they earn at level 5 lasts way to short to be effective. It should last more towards the length of the unique object that is given to all drow. In my opinion that unique object should also reset when the character rests so it can be used again.
