Autocasting Skills, coded from SRC

[ranmaster27]

I was wondering if it was possible to chain a skill after one skill hits, with an adjustable ratio based off of the SKL Level learnt.
I was trying to make it so the skill Envenom, can chain GC's Venom Impress and inflict it on the Target after Envenom has hit.

Having trouble making it work in the source code.
I looked at the code for Dark Illusion chaining off, Cross Impact, but I wasn't able to replicate it.

Also, how would I go coding, an autocast skill from a normal attack, like how Monk's Raging Trifecta Blow works?

EXAMPLE: If Knight is equipped with a spear, if they learned the Skill, Pierce, it will Autocast Pierce when normal attacking. Cast rate is based off of the skill level learned.
RO's got a lot obsolete skills, and I was planning on turning them into Passive/Autocast skills, so Hot Keys can be focused more on Active Key Skills, rather than 3 bars used filled with almost useless skills after class change.

Please let me know, and thanks much for helping.
