The abilities in the Occultist Archetype for the Arcanist are listed as spell-like abilities. However, to use them, you 'cast' them (at least, that's the term used in the archetype). This leaves a bit of a question for me.
1. Does it benefit from Augmented Summoning (as the Summoner's summoning ability does)?
2. Does it require components? Normally, spell-like doesn't...so then, no gestures for summoning a creature...and no spell component cost for the augury ability.
