stacking rules for archon's aura of menace

[khachaturian]

what are the stacking rules on
- archon's aura of menace
- halo of menace
- shaken

my guess is that the aura and halo shouldn't stack, but raw, the penalties are untyped

i am also thinking that shaken stacks, since it imposes a penalty on different qualities

All abilities are untyped penalties from different sources, thus they all stack.

From the Glossary (http://www.d20pfsrd.com/basics-ability-scores/glossary#TOC-Stacking):

Stacking refers to the act of adding together bonuses or penalties that apply to one particular check or statistic. Generally speaking, most bonuses of the same type do not stack. Instead, only the highest bonus applies. Most penalties do stack, meaning that their values are added together. Penalties and bonuses generally stack with one another, meaning that the penalties might negate or exceed part or all of the bonuses, and vice versa.
