New items: Isle of Wrath & Isle of Incantation

This is just a thought, but how about an item that grants you stats based on what the enemies are building? It would be a pretty good item offering "some" playstyle depending on the confidence of a single player. Here's the while detail about both items:

Isle of Wrath

+ + = 2000 gold total

+40 Armor

Unique Active: Fires a cursed soul that latches onto a single enemy and grants the user the victim's labelled passive stats. (120 second cooldown) Unique Passive: User will be granted 40% of the affected enemy's total AD, plus an additional 0.5 bonus AD for each occult stacks.

Isle of Incantation

+ + = 2400 gold total

+50 Magic Resist

Unique Active: Fires a cursed soul that latches onto a single enemy and grants the user the victim's labelled passive stats. (120 second cooldown) Unique Passive: User will be granted 50% of the affected enemy's total AP, plus an additional 1 bonus AP for each occult stacks.

I'm pretty bad with the numbers, so others are pleased to share your thoughts or edits.
