I'm wondering if the good Lore-Masters of Middle Earth can help fill in my knowledge er...Lore a bit.

What are the features of these effects: a)Slow, b)Daze, c)Root, d)Stun.
In particular:
1) what stacks with what
2) what can be ended by damage
3) what blocks what
4) what has an immune after effect (immune to effect for x seconds)

Example:
b)Daze: Can't act at all
1) Stacks with Slow (slow continues after daze ends)
2) Can be ended by damage
