If I take the Staff Fighting feat, which lets me treat a staff as a double weapon, can I use the Dual Implement Spellcaster feat with it?
Yes. Moreover, the character builder allows this and attributes the damage bonus accordingly.
Hurm. RAI, I agree, that this shouldn't fly. The caster is getting double the enhancement bonus of his item added to damage essentially for free.
Free? It costs 2 feats... One of which has a dex requirement, the other a wis. Far from free.
No, its a double weapon, but still only 1 implement. Similarly, if you took Arcane Proficiency (Heavy Blade), you couldn't use a double bladed sword with dual implement spell caster.
Keep in mind, to get ANY bonus from the second implement, he'd have to get the Dual Implement Wielder feat anyway, so it isn't appropriate to count that in the "cost" of this concept.
That said, sure it costs one feat to make the staff a double weapon, but for the price of that feat you're getting a "double the enhancement bonus of staves for damage rolls". Is that balanced with the usual requirement from users of the feat of having to buy an additional Implement to carry? I guess that will vary from DM to DM.
