HERO system!
Ah..you mean for D20. Well, HERO still has an answer for you- the Focus.
Foci in HERO are a little different from those in D20. They are sources, enhancers, or conduits for powers. Using that concept in D20 would involve creating magic items that allow a PC use a feat or feats as if they had taken it. If the focus is stolen or lost, the ability to use those feats embodied in the object are also lost- much like a Ranger donning Full Plate and losing his 2WF ability.
Example: if you wanted to create a mage who had access to ALL of the Energy Substitution feats, he would make (or have made for him, or go on a quest for) "The Lens of the Elements," a concave lens of black opal set in platinum which would allow the spellcaster to change the elemental nature of a spell he is casting as he casts it through the lens. (Details up to the DM & player creating the item.) Perhaps, instead, it would allow use of the feat Energy Admixture.
If the player is serious about it, have him take the Feat Craft Wonderous Item, a few craft skills (like metalworking or glassblowing) and start turning out the Foci!
*sigh*...I miss Austin & Dragon's Lair. So few places like it in D/FW- and you have to drive forever to find them.
