Do Alchemist extracts stack?

[Elibdis Killstrokian]

Just wondering if alchemist extracts stack like spells do.

[Elamdri]

what do you mean by "Stack"?

[ossian666]

Like can you have more than one extract (invisibility and enlarge person) going at the same time? Yes.

Can you drink enlarge person and enlarge person to double the effect? No.

[Elibdis Killstrokian]

exactly..multiple different extracts

[John-Andre]

Also, can you have multiple spells of different origin (say, wizard enlarge person spell on top of alchemist enlarge person extract)? Also no.

[Elamdri]

Basically what they said:

Spells of the same name don't stack (So no Double Enlarge Person)
Also, the affects of some spells don't stack (So no Haste and Divine Power)

But you can stack different spells all day (You are an invisible, flying shielded, enlarged, barkskinned alchemist if you want)

Extracts work like spells. If is in spell form, or extract form, it is treated the same.
So, if two spells stack, then two extracts stack.
