NHF – new heroes for Heroes V 3.1.

Here are a few ideas for Dwarf hero specializations:
1) All water, air, and earth elementals that join the hero's army become fire elementals. Also, after each battle, for every Tier 7 Dwarf unit that dies, the hero receives +1 fire elemental for every 6 levels of the hero. (Brief outline for bio: specialization in elemental energy of the fire element. The hero converts elemental energy of other elements into fire energy; also uses the released energy after dragons die to summon elementals).
2) The hero can move between captured mines (conceptually through underground tunnels), losing all movement points, with distance increasing with level.
3) Increased reward for clearing a treasure chamber if it is already scripted, as I haven’t played in a while (maybe this applies more to Orcs).
4) Each time the hero gains a level, they reveal a relic or major artifact on the map. When picking up an artifact, the hero replenishes mana and movement points.
This is what came to mind first; I might think about it later and come up with something better and less far-fetched.
