Devourer - An Idle Thought
I had something like this written in another thread, but I thought I'd simplify it.
+25% Base Attack Speed +30% Attack Speed +30 Magic Damage On-Hit +30 Bonus Gold per Large Monster Kill
Passive - Devouring Spirit: Takedowns on enemies increase the on-hit Magic Damage of this item (max 30):
- +1 for Large Monsters
- +2 for Champions and Rift Scuttlers
- +5 for Epic Monsters
Sated Devourer: Upon reaching 30 stacks, the item transforms into Sated Devourer, granting an additional +25% Base Attack Speed.
As an example of how the "Base AS" bonus looks, here's a level 4 Master Yi having just bought the item, not factoring in AS runes or masteries:
Current Devourer: 0.679 x 1.545 = 1.05 AS Modified Devourer: (0.679 x 1.25) x 1.345 = 1.14 AS
And let's say he happens to Sate it at level 9:
Current Devourer: 0.679 x 1.635 = 1.11 AS plus Phantom Hit (1.31 during Highlander) Modified Devourer: (0.679 x 1.5) x 1.435 = 1.46 AS (1.77 during Highlander)
Since all forms of Attack Speed are calculated as Bonus AS based on your champion's Base AS, increasing Base AS has the net effect of granting you more out of any other AS you build/gain per level. The idea being that Sating it should still grant a fairly sizable bonus without all the "wtf how is this balanced" Phantom Hit nonsense.
It has a simple purpose. Give extra damage, grant AS, and let you benefit more from the AS you get otherwise. You know, like Cinderhulk and Runeglaive do with Health and AP respectively.
