The original "Rage of Bahamut" ("Shingeki no Bahamut") is a fantasy adventure game in which players roam the world, drawing out powers from cards. After choosing between 'Man', 'Gods' or 'Demons' cards, players build and strengthen themselves as well as their teams by collecting, synthesizing and evolving a variety of unique cards.
The cards are then used in various team oriented activities such as order vs. order 'Holy Wars' or order vs. game events such as "Dragon's Awakening", or "Hermit in the Hood".
Three anime series have been adapted from the game, "Rage of Bahamut: Genesis", "Rage of Bahamut: Virgin Soul", and "Manaria Friends".
Holy Wars (now called Onslaught).
Holy Wars are periods averaging five days in length in which groups of players (orders) work to try and defeat each other. Every successful attack and defeat of an opposing player earns points for the player and the order, as well as adding one 'link' to the attack chain. Whichever order has the most points at the end of a battle period wins. Battle periods typically last 90–120 [60 min in US version] minutes. During battles order members usually utilize 'Holy Powder' to fuel their attacks and create attack chains which further multiply 'Holy War Points'. Successful player vs. player (PVP) attacks and wall/castle attacks give 'Spell Power' points as well which are used to boost the entire order's or a specific members's attack, defense, and holy war points earned. On June 24, 2014, Holy Wars was suspended to improve on other factors of the game. Due to this, all previous cards with skills for Holy Wars will convert to Castle Crushers skills. When Holy Wars are resumed, the skills will revert. Currently, Holy Wars is discontinued for other events.
Holy Wars (Onslaught) Position Skills.
Each different position within the order has a specialized spell power ability unique to that position. The order leader's position skill is called "Shingeki" and when activated it raises each order members attack and holy war points gained for a period of ten minutes. The vice leader's position skill is named "Braveheart" and when activated it raises order members attack, defense, holy war points gained, and does not allow opponents to use "Full Force attacks". The vice leader and order leader cannot both activate their position skills at the same time. The position skill for defense leaders is named "Phalanx" and causes the defense leader to be the only one opponents can attack, and boosts their defense while also assuring that attacks of less than 50 attack power will not decrease his defense power. It lasts six minutes. The attack leader's position skill is named "Warcry" and it lowers opponents defenses by a significant percentage but it only lasts one battle. The support leader's position skill is named "Boost" and it recovers another member's attack power and defense power, or provides a defensive boost to one player. Finally regular member positions can "Yell" at other members to restore attack power and spell power.
Events.
Events are created between Holy Wars. The Random Events typically have players engage in questing in order to 'discover' raid bosses and defeat them in order to gain prizes. The first tier raid bosses are required to be defeated before the second tier, larger bosses may be 'discovered' and there are typically three of them. The raid bosses continually gain levels, attack, and health points as they are defeated and their rewards multiply along with the difficulty in defeat and the length of time given to defeating them. The first tier raid bosses will only allow the primary attack and those called for aid to cooperate in bringing them down. The second tier raid bosses allow all attackers to request aid from others though up to a given amount of typically 100-200 players. Events differ from Holy Wars and the game-long quest in that players are allowed to use ten card decks rather than the standard five, and there are specific "event cards" whose skills increase damage to raid bosses in events.
In-game currency.
The in-game currency of "Rage of Bahamut" is named "Moba Coin" [or RageMedals on iOS for the World/US version]. Moba Coin can be purchased with real money and utilized to purchase card packs, holy powders, cure waters, and magic circles. Players in game primarily hold holy powder in highest esteem and utilize it to purchase cards from the auction house "Bazaar", trade for other items, or use it in Holy Wars/events to gain a higher ranking and reward.
Theft.
Initially, "Rage of Bahamut" had no restrictions on what could be traded to other players, how soon it could be traded after acquirement, and how many alternate profiles could be created in order further players abilities to create strong carded decks. There was no bazaar system in place so players were required to depend on others for their cards and items. But a massive plague of account hacking occurred and after it [shut down all events, in-game purchases and trading capabilities for 3 weeks, causing many players to become restless.] "Rage of Bahamut" did not allow trades [for new players, between newly formed fellows or new members to an order] for two weeks and set up an auction house system to replace the requirement of player-player trades. It also implemented a more secure way to make sure accounts are safe from hacking attempts.
