The pool can have multiple sources of dice. For example, the number of dice in your initiative pool is the sum of your strength plus your dexterity. It can be modified by a feat (they're called talents, but they smell just like a Pathfinder feat), or other sources.
Modifiers can be positive (add dice to the pool) or negative (remove dice from the pool.) The modifiers currently behave this way.
So Initiative pool = Strength pool + Dex pool [+mod]
In general, two parameters for dice, and one for a permanent modifier, should suffice.
Does that help?
