Investigator extracts in combat.

[hughnme]

Quick question,does imbibing an extract in combat as an Investigator provoke in combat?

[logan grayble]

Yes. While not being a potion, they're activated like potions, which provoke an attack of opportunity. The opponent may also choose to target the extract instead.

There is no reason to think it works differently than for an Alchemist. The design team commented on that yesterday HERE. Yes, it provokes.
