Threat / Hate Bonus Stacking

[Lansirill]

How do multiple increased threat/hate generation abilities stack? I've searched around and I haven't been able to find an answer to this. Do stalwart defender stances and dtouched armor bonuses stack? Can I get a bonus from both my dtouched armor and the vulkoor's might set bonus? Heck, if I put the +10, +15, and +20 runes on some dtouched armor, will I only have 120% increased threat, or will I have a 1.1*1.15*1.2 bonus?

Thanks.

I imagine it's hard to calculate. Compared to something like Healing Amp, where you get exact numbers (especially w/ the HEAL spell which makes calculating healing amp easy), Hate is just guestimating.

My guess, it stacks like Healing amp (different sources multiple) 1.0 * 1.1 * 1.2 ... just guessing
