Is it possible to have the same mount bonus twice? For example, if I had two mounts providing Warlord's Inspiration (+20% companion damage), would that yield any more damage than just one? Or, if I had two mounts with Wanderer's Fortune (4% chance to find refining stone when killing a foe), would my odds of finding a refining stone increase?
If two mount bonuses are the same except for numbers, do they both take effect independently? For example, Vampire's Craving would give me a heal over time when I use Lifesteal. Vampire's Thirst would also give me a heal over time when I use Lifesteal. If I had both, and performed a Lifesteal, would both trigger, and take effect independently?
The target I've applied my mark to Most recently is considered my Mark Focus. How does this interact with effects that apply Mark to multiple targets simultaneously?
If there are two Guardian Fighters in a group, and they both Mark the same target, do the Marks stack? I mean, I assume each player gains the benefit of extra threat versus that target. But what about the debuffs inherent to Mark? What about the debuffs that can be added to mark with feats?
