[UC] A Ragechemist question

[Irall]

I have buy the new book Ultimate Combat the other day and while looking at the Archetype for the Alchemist,somethign attract my attention:The Ragechemist Rage Mutagen ability.What it do is ,whenever I do a mutagen that boost my STR, that mutagen grant a +6 bonus to STR and a +2 bonus to armor(Natural).My question is,do this is in adition to the normal bonus,or do it replace it,because,at the discovery section of this Archetype,it said that Grand and Greater mutagen compliment this Archetype,but,if it replace it,there no sense to get those Discovery.Can somebody help me?

actually it never types the bonus, so i think it stacks with everything.

i believe its intended to give you an effective +2 to the normal mutagen bonus, so total +6 normal, +8 with greater, +10 with grand mutagen

[Irall]

Make sense,thank you^^

well i read the class ability like this; if your mutagen enhance your str you get a +6 untyped bonus to str on top the same with nat armor. So in the end yyou get +10 to str with normal mutagen +12 with greater +14 with grand mutagen.

i read it as it replaces the normal bonus. whenever you drink a str mutagen you get +6 str total.

it may not stack with the higher level ones except the gain str from damae ability
