dark fall is:
Darkfall is a massively multiplayer online role-playing game (MMORPG) developed by Aventurine SA that combines real-time action and strategy in a fantasy setting. The game features unrestricted PvP, full looting, a large, dynamic game world, and a player skill dependent combat system free of the class and level systems that typify most MMORPGs.
Skills
Darkfall departs from the conventional MMORPG paradigm of character levels as the main form of character progression, favouring instead a broad skill-based system[4], similar to that found in games such as RuneScape, Ultima Online, EVE Online, Wurm Online and Asheron's Call. Skills and skill proficiency determine a wide range of a character's capability in the game, including weapons and weapon skills, a few special attacks, spells, and archery, all aspects of player crafting, as well as more basic facets of gameplay, such as the ability to swim, craft various items types, and to ride and control mounts.
Skills may be learned from NPC trainers in the game, however certain skills will require other skills as prerequisites. Without exception however, skills are improved (raised in power) through actual usage in game.
