spell stacking

Looking for a reference here, if you folks can help out.  Can multiple casts of the same spell have stacked effects on the same unit.  For instance, double casts of Wyssan's on a unit, or doubles casts of Soul Blight on the same unit.  I'm 90% certain that they do, but some confirmation would help.

Well, since the only time that duplicate spells happen is with signature spells, I don't think the rules really take this question into consideration.

However, since they are different instances of the same spell, they do stack. I think for the most part, though, most of the sigs don't really have effects that can cause "stacking", but yeah, double Wyssan's works, as well as double other buffs/hexes.

There's a few things like warlocks and sisters that could have doubles of the same spell.

I believe in a general sense spell effects stack, special rules do not. So you can have multiple wildforms on a unit for +2 strength and toughness. If you cast aspect of the dreadknight on a unit twice you still only have one instance of fear, or if you cast earthblood on a unit twice it only has regen once.

There are other ways of getting duplicates, including loremaster, bound items, units with set spells, etc.

As far as I know there's nothing stopping you from stacking multiples of the same spell from different sources on the same unit.

If you are able to cast multiples of the same spell, its effects will stack. Obviously only effects that can actually stack will do so, so a simple Stat increase will stack(such as from Wildform) but having Frenzy multiple times is just the same as having it once.

So double iceshard blizzards becomes pretty potent too.

O'yeah!

Its funny when at best your opponent will have 5s to hit.
