Augmentation noob questions

[mcast]

So I extracted my first aug and applied it to an armour piece, in this case it was a +4 speed mod for psychology. It got me thinking about aug stacking;

Could I extract 9 +4 speed augs and put one on every piece of my gear, giving +36 runspeed?
The follow up obvious question, can you have multiple damage augs for one skill, eg 9 x 50% damage giving an exponential amount of damage?

Thanks.

Psychology only gets +x speed boost treasure effects on head and feet. You can use 1 head one and 1 feet one, so you are can only get 2 total of that mod.

You can stack different damage mods for a skill and or an ability of that skill.
There is a website that let you see and try out all sorts of info on treasure effects.

Most mods appers on two different pieces of gear, with few exceptions (for example, mods that turn single-target skill into AOE usually apper only on gloves). You can stack the same mods (for example if you have two +50% dmg for x ability, you will get +100% damge). Hoever you can't have the same mod on every piece of gear.

Tried to get a mod from an item, it didn't ask which one and I ended up with a useless aug. Is extraction random?

Yes it is random, best to do on green gear that tend to have what you want.
