Why Warrior is the only jungle enchantment without a special effect?
---> You stack HP, this item increases your HP further. It is essentially an HP 
.
---> It is a mini-
that restores your mana when used against monsters (and also does AoE damage to them). On the PBE it is being changed to act like a mini-
(it can still restore mana when used on monsters).
---> It initially acts like a mini-
that can't shred magic resist. However, when stacked enough, it allows the user to double on-hit effects every other basic attack. The latter is actually an unique effect not found on any other item that has ever existed so far.
As for 
- it has nothing special. It is just pure stats, offering only AD and CDR, without a special effect. It used to offer a 10 flat armor penetration, but that was removed, but even that isn't a secondary effect; it is yet another raw stat. Granted it gives an high amount of AD, but that falls off as the game goes on, especially if your opponent builds armor. It is only good for increasing abilities' damage. Why it doesn't have a special effect like other jungle enchantments? Is it really meant to only act as a means of increasing damage from AD-scaling abilities?
Fun fact: There was an old jungle item named Spirit of the Elder Lizard, created for AD casters, that had an extremely good special effect. It dealt bonus true damage whenever you dealt physical damage (either with your abilities or your basic attacks).
