So, the Metamorph Alchemist's description is a little lacking when it comes to saying what discoveries they can or cannot take. Would I be correct in assuming that they can take any discovery that does not effect class features they don't have like bombs or other alchemy abilities like extracts?
TL;DR: Can Metamorph Alchemists take discoveries like Chameleon and other flavorful discoveries that would presumably also work with their shapechanging abilities so long as they don't require alchemy?
EDIT: Also, since the Metamorph doesn't technically get spell slots or really have a caster level, how does the Wings discovery work for them? Do their levels count as caster levels even though they don't get spells since the base class being modified gets spells or is the whole thing moot and they can just sprout wings and gain a fly speed via shapechanging? and
