(VX) Chance On Hit Effects

Just like on WoW, I'd like a way to implement chance on hit effects to occur. I know state changes can already occur, but I'm interested in the possibility of adding another effect. Basically, what I'm interested in is something like this:

Fireball
(description) Hit an enemy with a ball of fire, dealing fire damage. Chance on hit to fire a second fireball for half damage.

Notebox:
\CoH 10 half


In other words, I'd like this to be built to use tags in note boxes. A few examples of extra effects:
\CoH 10 half = uses the same spell immediately following the first to hit for half damage, where 10 = the chance to occur
\CoH 10 full = same as half, but hits for normal damage


In addition, I'd also like to be able to add on extra effects to States.
Example:
a damage dealing state deals damage, but it has the chance to deal critical damage. would also be nice to be able to have states that do damage be able to deal damage based on attack or spirit (to gain benefit from your stats as skills do)

the major one I want for states is the ability for a state (based on a given chance) to activate a common event. maybe a command like
\CoH 10 CE

if a number is necessary to determine which common event is to be called, that could be added after CE (again the 10 represents the chance for it to happen)

Additionally, I'd like to see if I could also be able to do something like the Fire mage talent Ignite, where a variable damage over time state is afflicted (with the condition that it's only applied when the skill critically hits) and it deals X% of the damage dealt in the initial hit either after 1 turn, or over a few turns.

bump!!

Anything?
