First, remove this
EditPackages=IpDrv
EditPackages=UWeb
EditPackages=GamePlay
EditPackages=GUI
EditPackages=Runtime
EditPackages=RTInterface
Second, read when I tell you to "try compile" LineageSkillEffect" without your custom and show me log". This not "https://pastebin.com/VikX9WmD"
Third, this line is unnecessary, erase it
SimpleEffectClass=Class'Corasonskill.s_u807_mage_ca_simple
Fourth, that ability already exists in older versions (IL-Hi5). I don't know why duplicate.
Fifth, from "The Kamael (after Interlude)" so far only skills are supported within the "LineageSkillEffect" package.
So this "https://pastebin.com/p70CACSW" goes inside "LineageSkillEffect" with another "SkillID"
Sixth, I don't know if you are looking to create skill for Hi5 or IL. I guess Hi5.
