Invitation to the map community in

  • Custom Combat System, which includes a lot of custom combat parameters like spell power, healing bonus, block amount etc. and various damage types as well as creep aggro system. This allows to introduce WOW-like hero roles: Tanker, Healer, Damage Dealer and Mage. Heroes in-combat have different mana and health regeneration, can use only a certain number of potions and elixirs.
  • Simple Item Upgrade System, which at the same time gives variety of leveling. Each item (weapon or armor) has 4 ways (=glyphs) to upgrade, which add unique abilities to them. No recipes, just buy a sword or axe for your damage dealer or staff for a mage or a healer and choose the glyph, which gives an appropriate ability.
  • Unique heroes with custom abilities and talents, which make possible different leveling styles and synergy with each other
  • Meat, but hardcore gameplay, which dynamically varies from 5 difficulty levels, number of players and party setup.
  • Single player regime with single or multi-heroes mode.

Basic Hero Stats:
  • Critical Strike: chance to deal critical physical damage on hit.
  • Critical Power: the ammount of critical physical damage (crit multiplier).
  • Block Chance: chance to block a physical attack, reducing incoming damage.
  • Block Amount: the ammount of physical damage to block
  • Spell Power, Spell Crit: improves spell damage or healing and gives a chance to spell crit/heal crit respectively.
  • Healing Bonus: a bonus percent of healing to all healing effects done by the hero.
  • Haste: a chance to deal next attack immediately. Hasted attacks cannot be hasted again. Has a twice lower effect on ranged heroes.

Some Combat Mechanics:
  • Creep Aggro System: every hero increases the threat value when dealing damage to the target enemy. The ammount of threat generated by one point of damage depends on the hero class, ability used and can be affected by some abilities and items. Every creep attacks the target with the highest threat value. Type "-sa" to see the threat values (in percentages) of allied heroes on the enemy creep.
  • Combat/Out of combat system: every hero enters a combat when deals any damage to enemies, receives damage from enemies or heals (or gets healed by) an allied target in combat. Combat affects the ammount of healing and mana potions (to 3) and elixirs (to 1), which can be used during one combat. To leave the combat hero must not receive or deal any damage/healing for a certain ammount of time, which depends on the difficulty level. While in combat the regeneration of mana depends on the hero spirit. Outside combat the hero regenerates 10% of health and mana per 5 seconds. Heroes with Rage as energy restores it only by dealing damage in combat and slowly loses it they arewhile out of combat.
