Dota 6.59 changelog
* Some performance improvements
* You can no longer attack items you do not own if they are in the fountain area
* Fixed some rare memory corruption bugs that could cause random abilities/items to malfunction or result in a fatal error
* Added a new subtle cooldown effect to make it a little clearer when spells are in cooldown and when they finish. This is mainly for long cooldown spells where it is sometimes difficult to tell.

More work will be done in this area soon, but it needs a bit more time to make sure that anything extra is not visually intrusive. (PGRu-Unexpect3D)

* Increased Fury Swipes buff duration from 3 to 5 seconds

Demonic Conversion:
=====================
Splits any non-hero unit into three Eidolons, killing the targeted unit.
Eidolon's can duplicate themselves once whenever they attack 6 times.

Lesser Eidolon/Eidolon/Greater Eidolon/Dire Eidolon (Same as before)

Cooldown: 35
Manacost: 170

Notes: It cannot target Level 5+ Neutral Creeps



Experimental Runes
====================
This temporary mode changes the rune system to a more experimental one. I will be changing how -er works from version to version to try out different ideas. I don't plan on any one version of the new runes to replace the current system directly, so do not panic Instead, it will be used as something to create discussion, spark ideas, find flaws and playtest different concepts over time.

How -er works for this version: Runes spawn simultaneously on both sides at 3 minute intervals (instead of 2). Again I have no plans to make this permanant.



Notes: I wanted to release this sooner rather than later because of some important code fixes. I am planning on finishing the traditional .x9 quest for v6.59b (along with some more balance tweaks) and then followed by TC in 6.60 if everythings work out right.
