1 . I think is all about speed game .. run so fast and we dont see in real time ..exemple : slot 1 2 3 4 attack .. and later clone(wind clone ,spiders so on ) attack .. if you use skill when your clone attack .. he will cast next round because round is already over after slot 4 attack not after all clone use standart attack

2. round 2+ .. if you use instant mastery when round start he will cast by initiative .. if you use in middle round .. all mastery become non-prompt
