Multiple Djezet Draught

[Fedor Checherov]

Greetings!
Do effects of multiple Djezet Draufgts stack or not? Djezet Draught https://aonsrd.com/MagicItems.aspx?ItemName=Djezet%20Draught&Family=Sta rmetal%20Serums

A) Yes - Djezet Draught bonus untyped, and Bonuses rule "Bonuses that do not list a bonus type do stack, both with each other and with all typed bonuses." https://aonsrd.com/Rules.aspx?ID=154

B) No - Djezet Draught is magical serum and Combining Magic Effects rule "Spells and effects that provide bonuses or penalties to attributes such as attack rolls, damage rolls, and saving throws usually do not stack with themselves if multiple effects would apply to the same attribute." https://aonsrd.com/Rules.aspx?ID=220

?

The second one. Effects don't stack with themselves is a general rule.

Interestingly, I can't actually find it explicitly stated anywhere in the CRB. There are multiple locations where it is inferred, including a reminder that penalties from the same source don't stack.

The answer is clear, but I think I'll mark it as a FAQ and maybe a couple of words will be added in the next printing.

When multiple bonuses apply to the same value, different types of bonuses all apply, but in most cases bonuses of the same type do not add together (or “stack” with each other), unless a source specifies otherwise. (For an exception, see Circumstance Bonus below.)

Unnamed bonuses stack with OTHER unnamed bonuses. Multiple Draughts are the same bonus
