Eldritch Glaive and Weapon Finesse

[Dr. Cliché]

Can you use Weapon Finesse when making attacks with an Eldritch Glaive?

[Talya]

As I recall, yes. Eldritch Glaive is not a physical weapon, but a series of spell-like touch attacks. Weapon Finesse applies to touch attacks.

I believe so, yes. The book states it appears similar to the glaive, not that it creates an actual glaive, and is a melee touch attack. You can finesse a regular melee touch attack, so it should work.
