[HoMM V]9 Race - Swamp! Is it needed?

go ahead and post it... but think about other creatures, it will result in 3 elf races... that's great... but you can adapt it for Stronghold and other factions...

P.S.: I mentioned one building earlier, evaluate and criticize it, and what about abilities? should we come up with them? and please write about the racial ability and the hero's abilities, I understand that the ability is "artifact breaking"...
