this is actually pretty simple crit works as you say for sting make a new spell; use poison (from gnoll archers) and make it do w/e ya want it to do; for slow use slow poison, for corruption unfortunetly u cant have it have a picture i think... though make an additionnal spell (bash for ex..) and make bash have the exact tooltip youd like corrupt to have (though the ''bash'' doesnt do anything (make it have 0% hit to bash) goodluck with w/e your doing.(remember to put in all 4 abils, poison, crit, corrupt, and bash/tooltip.
