Demon Realm Voyage

Introduced by MyNet on January 10, 2019 for the New Beginnings event and Rebirth cards, Demon Realm Voyage adds a new challenge for players requiring more diligent Team Building having stricter elemental advantage, and new attack patterns for enemies.

Event Structure
The event structure is very similar to Tower-Type Events where the player starts with 5 battle points which replenish one point every 45 minutes. New items ( and ) can be used to replenish all your battles points.

Using a battle point starts the player on a map which has a set number of battles based on the difficulty. The map is timed and must be completed in 30 minutes to earn all the rewards. All the difficulty levels start locked except Beginner and unlock as you earn event ranking points. While on the map, the player will encounter different area types offering different advantages/disadvantages and difficulties based on the area type. The enemies found in the different areas are Demonwitches.

All maps start the player on a single random area that they must clear to advance. Once cleared, the player is offered 2 areas to choose from. Once one area is selected, the other area becomes disabled and the player must complete the selected area to continue, even if their team loses. This area choice continues until the final area which is always a Boss Area.

Unlike towers, clearing a single enemy area will earn the player ranking points. However, to obtain all the treasure found, the entire map must be complete, defeating the Boss Area.

Demon Realm Voyage has a "fever" session like Tower-Type Events or Alliance Bingo Battle. To activate the fever, you must collect 4 map pieces that drop randomly from the treasure chests. See the Hidden Lands section for more information on how this part of the event works.

Demonwitches
Battles with Demonwitches differ from other events in that between battles, the cards Soldiers and Skills will not replenish (although they recover once the Boss is defeated or an extra Battle Point is spent to recover). Demonwitches attack in a new attack pattern called "Waves" starting at intermediate difficulty. A single team must either clear all the attack waves, or perish before selecting another team. Once your team has perished, it can not be used again unless you spend a Battle Point, which will fully revive all teams soldiers and skills.

TBD: mention the shield (Demonwitch Spirits skill) along with elemental damage protections in general

Hidden Lands
One of the possible drops from treasure chests when you clear a stage map is Demon Realm Map Piece. If 4 pieces of this are collected, the Stage Maps will turn into Hidden Lands stages for 30 minutes. If the time limit ended while you're in Hidden Lands, the background will revert to Stage Map, but all the areas found will continue to be treasure areas.

Unlike Tower Rune Time, Hidden Lands do not give increased amount of points from clearing areas. It instead turns all areas, except for the boss area, into treasure areas. Both treasure area and boss area give the highest Demonwitch hunt points possible from an area.

Hidden Lands increases the number of treasure chests received from clearing the Boss Area - from 3 treasure chests to four treasure chests. The extra treasure chest always contains s.

Level of Difficulties
Each difficulty offers approximately twice the amount of rewards per area fight as the area below it (see Area Types for more details). Due to this, doing a harder difficulty is often beneficial as long as it takes no more than 2 battle points (BP) to complete. For example, If a player can normally do Intermediate difficulty with 1 BP, but it takes them 2 BP to complete Advanced, the player will always earn more ranking points doing Advanced. This is because Advanced has 1 more battle (4 instead of 3), so it's as if the player completed 8 fights in Intermediate, when with 2 BP they would normally only complete 6 fights total in Intermediate. This "battle-up" strategy works for both Intermediate→Advanced and Advanced→Extreme, but not for Beginner→Intermediate as both the lower difficulties have the same number of battles.

The downside of doing the battle-up strategy is the possibility of getting less map pieces for the, but since there isn't a huge benefit of Hidden Realm like other event with "fevers", it's not a huge loss.

Rewards
Rewards are given for reaching certain points as well as from clearing Stage Maps or Hidden Lands. Point rewards change each event and can be seen in the event details and ranking screens in the game.

Area Clear Rewards
Area rewards are from clearing an area within the stage map. They are given only if you clear the stage map. They include the following:
 * Demonwitch Hunt Points - used to determine Demon Realm Voyage ranking. The amount is dependent on the level of difficulty and kind of area.
 * Survival Bonus Points - additional points from finishing the area are added to the points used to determine ranking. Survival points are given only if at least one card from the first team you used to fight survived the area. The amount is dependent on the number of surviving cards.
 * 5-card survival - 20% of Demonwitch Hunt Points
 * 4-card survival - 15% of Demonwitch Hunt Points
 * 3-card survival - 10% of Demonwitch Hunt Points
 * 2-card survival - 5% of Demonwitch Hunt Points
 * 1-card survival - 0%
 * Treasure Chests - amount dependent on the kind of area.

If you retired from the stage map without clearing all areas, the treasure chests earned from clearing them are forfeited.

Stage Map Clear Rewards
Stage map clear rewards are given from clearing a stage map. This include all the Hunt Points, Survival Points, and treasure boxes from area rewards.

The rewards from the chests are random and can include the following cards and items:


 * All N cards that are available from Regular Summon.
