The investigator talent Alchemist Discovery says

The investigator can select one of the following alchemist discoveries as an investigator talent: combine extracts, concentrate poison, dilution, elixir of life, enhance potion, eternal potion, extend potion, infusion, mutagen, and poison conversion. When selecting an alchemist discovery, he must be high enough level to qualify for that discovery, using his investigator level as his alchemist level to determine if he qualifies. This talent can be selected multiple times; each time grants a new alchemist discovery.

Based on this wording, I wonder if the only prerequisite for alchemist discoveries through this method is the level requirement. For example, if I wanted to pick up the Eternal Potion alchemist discovery from investigator talents, can I avoid the extend potion prerequisite?

A thought: Fabricate arms says "Treat this as a spell of the same level as the expended spell slot." With that in mind, could one double the duration of a fabricated weapon or armor with the use of the extended spell magic hack?

My only devil's advocate counter argument would be that Extended Spell's text says "When you cast a spell...", but does "Treat this as a spell..." mean you're considered to have "cast" it.
