Name of the spell: http://www.db.pandawow.me?spell=129413/mind-numbing-poison
Whats the issue: Whenever you apply the Shiv effect from Mind-Numbing Poison to a target,he gets a debuff called Mind Paralysis > "Increases the casting time of an enemy's next spellcast within 8 seconds by 100%." During that time,any instant abilities will remove the effect,such as http://www.db.pandawow.me?spell=45525/arcane-intellect or http://www.db.pandawow.me?spell=30455/ice-lance etc.
An example with Arcane Intellect: https://gyazo.com/39c16706f74c8e6a06d5ebef4d505ac6
How it should be: It should not remove the shiv debuff unless you have used an ability with cast time or simply dispelled during that 8 seconds duration.
Date when tested: 23rd of September 2017
Realm: x100
Priority of the problem: 8/10 Only because it makes this Poison hella useless.
P.S I can also link every single instant ability which i tested with,if its needed.
