pros +escapes easly because of Poison Trail +getting tanky for buying mana(because of Empowered Bulwark) + Fling can make your enemy crazy( Flinging into turret,into your own team etc.) +his Mega Adhesive is very helpful in mid-late game + Insanity Potion is a HUGE steroid that raise almost all of his stats(health and mana regan,movement speed,AP etc.) +one of the best farmers in game +hard to kill

cons -cant attack from distance(if not being chased he have to walk near the enemy for Poison Trail to work) -dont have hard cc(only Mega Adhesive that is not helping until he is in high rank) - Fling range really short - Insanity Potion is kind of a temporary buff (not an actual "attack") -weak early game -extreamly mana hungry until Rod of Ages
