PM Hey I'm pretty much new to the witcher 2. Bought it and the first one during the winter sale and I find it to be and incredible game. So my question is can I stack up the buffs of potions like say I take a potion that buffs my incineration by 30% then take another that buffs me up by 40%. If I take both of them up will I get a 70% buff and also how does that affect the duration?

Do potion buffs stack up?

There will be no effect on the duration (each separate potion will have their own duration, but the duration is usually the same for each potion), but the effects will indeed stack. This does not necessarily mean that they will stack as you think, though (30 + 40 = 70!), as the effect formulae of the potions work in different ways. Some items will add a raw bonus while others work as a multiplier to what you already have, which will increase your current value by a certain percentage.
The problem is that CDPR did not think to make this evident in the game, within the tooltips; they simply use "+%" no matter which effect is applied, making it hard to know which one is a raw bonus and which one simply multiplies your current value.
EDIT: Looking through the default files, now, I see that this does not apply to potions. When it comes to critical effects of potions, they always work as a multiplier. How multipliers effectively stack with each other, I can't say. The effects will not overwrite each other, but I don't know how the calculations will work inside the game.

Potions are all multiplier-based as Kindo says, with the exception of Golden Oriole/Lapwing where the critical resistance is an absolute value. And +1 to his remark that CDPR hasn't done anything to make the difference between multiplier bonuses and absolute values clear...
Just to clarify, multipliers are always applied 'on top of each other' so a +40% and a +30% would mean 1.4*1.3=1.82 times the base value (a +82% in total), absolute values are simply added up in the way you suggested in your original post.

Neat. Thanks for clearing that up - math was never my strong suit, so this helps.
