ok, i totally prefer spells untriggered but these are just lame:
1) let see how meteor strike works: i cast it on a point, five peasants (test units) get stunned JUST LIKE THAT, and then AFTER ONE SECOND three or four flaming rocks fall from the sky missing most of those peasants (which are not stunned anymore)......
2) everyone can do slow aura - it can be easily based on endurance aura or unholy aura but you found a way how NOT to do it! not everyone could have found that.
3) turning creeps into chicken - while this one actualy works fine (one out of three), in most maps it would be useless - let's see: will i kill that creep for 50 gold and some experience
or turn it into chicken and walk away?
1/5 - nice try.
