Spell-like abilities and statblocks

[Totus Gnarus]

So spell-like abilities are listed similarly to spells, in uses/unit of time. I've never quite figured out if this is per ability, or if it represent a pool.

For example, a Wihsaak Sahkil has this on its statblock
1/day — see invisibility, suggestion (DC 15), unholy blight (DC 16)

Does this mean it can cast each of these abilities once per day, or it can cast a single ability once per day and must choose it from this list?

It means it can use each of those once per day. It will be explained if they have a pool, though I am on my phone right now and can't search up an example easily.

Good to know, thanks!

An example with a pool is the Amanusya Rakshasa, note the PE (psychic energy) section.

it's a common question.

see Univ Mon Rules SLA and other interesting FAQs
1/d means EACH spell listed can be used once per day. Thus 3/d and a long list is awesome.
