Vivisectionist (and archetype in general) question

[eleclipse]

So a player of mine want to do a Vivisectionist, but he started to argue with another player that say that when the archetype says:

"The following discoveries complement the vivisectionist archetype:..."

you can take only the discovery in that list, since i always took it like "these are the best / more role-wise choiche for che archetype, but are not mandatory" i was quite confused, it seem strange to me but maybe i got it all wrong?

So the question is, in this case and similar one, is the list of discoveries limited to the one listed in the archetype description or not?

Thanks in advance for the help.

That list is just meant as advice. It in no way replaces class features or conflicts with other archetypes.

Nefreet is absolutely correct. For archetypes with classes that have various "menu choice options", they give recommendations for how to best play up the flavor of the archetype.

Compliment doesn't mean mandatory, its just a list of discoveries that is there to be read over and forget- I mean err... read as advice. Its just someone else's idea of what that class should be.
