Hi.
This plugin allows you to override the npc_heroes.txt and npc_abilities.txt files found in the vpk and many others.
How it works:
-Extract the zip into your servers dota directory.
-Grab the heroes and/or the abilities file from the pak01 vpk (I use GCFScape for this)
-Place the files in the appropriate directory (dota/scripts/npc) and modify as you please.
What can you do with this?
-Change heroes abilities
-Change ability ranges/manacost etc..
-Other stuff... Read the files!
Thanks to:
