"HW rulez" mod (add-on) for HoMM3.

version 1.21:
+ In Arcomage Battles, elementalists start at level 1.
+ At the start of a random map, heroes from other factions will not appear.

Added 6 minutes later

Kaspersky is still causing problems for me. I can't use the mod. I suspect that a Trojan is interfering with the connection.

I don't even know. We tested it with 4 people who have Kaspersky. Since version 1.20, everything has been working normally for them. + The antivirus online test also started passing successfully.
Maybe a special version of Kaspersky was encountered...
