Hey folks, this is something Antaig and I have been working on for a while. It's a modified client that includes a lot of changes to the original HoN heroes and includes a pack of DotA heroes as well. Some of the changes are:
-attack abilities and atack modifiers no longer work together (Arachna's 1st for example)
-hero and item fixes are up to version 2.0.19 retail
-Demeted Shaman has Unbreakable instead of Arcane Hide
-Ancient Creep and Tower tweaks so they are the same as in retail now
-all the other small tweaks to the heroes and abilities from the retail patch
DotA heroes included:
1) Balanar the Nightstalker
2) Bone Fletcher
3) Bounty Hunter
4) Broodmother
5) Doombringer
6) Dragon Knight
7) Drow Ranger
8) Eredar the Shadow Demon
9) Herbinger the Obsidian Destroyer
10) Huskar the Sacred Warrior
11) Magnataur
12) Nerubian Assassin
13) Phantom Assassin
14) Pugna the Oblivion
15) Terrorblade
16) Troll Warlord
17) Ursa Warrior
With that all hero slots are taken.
Credit to a lot of the HoN fixes, improved client and simply for helping to improve HoN Lan to what it is now goes to ifrit, AdminReaper and Goranpn. Thanks guys!
