A Land Far Away

What are the chances on a skill synergy system, even if it involved only no-drop plot items with scripted +2 skill bonuses dropping when the requisite ranks were achieved?

I've scripted skill synergy into the Use Magic Device handling of scroll activation (from spellcraft ranks) - Haven't put any thought into making global synergy- while potentially do-able, may run into problems with stacking and skill bonus items and such. Is it something we can handle on the demand-side, instead of the supply-side?

What are examples of skills that give carte-blanche synergy to each other?

Stacking was one immediate potential concern. There's a list of synergies at the foot of this page: http://www.d20srd.org/srd/skills/usingSkills.htm

As the synergies only come into play when performing skill checks, we can at least build these synergies into generic skill check scripts for use in conversations and elsewhere.
