Hello. My name is Dmitriy. I am glad to present you my new map concept.
Codename: Floating Island
Picture - https://i.imgur.com/9uu3lFu.jpg
Description:
Citadels A and B have a durability of 20,000 units each. Strongholds are impregnable.
At 2:00 begins timer 30 seconds before the activation of point C.
At 2:30 point C is activated, and it works for 1:00 minutes.
Each hero who is in the field of action of area C, brings to the reserve team 30 units of charge per second.
When the time expires (at 3:30), area C is deactivated, and the Citadels shoot each other with accumulated charge.
(Example: allies accumulated 8,000 units, then allied citadel deal to enemy citadel 8,000 damage, reduce its durability from 20,000 to 12,000 units)
After 1:00 minutes after completion of C, a 15-second timer starts to activate points D1 and D2. The points are active 1:00 a minute, or until they have exhausted their charges.
Each point D has 5 charges. One charge heals the allied citadel for 200 units.
At the same time, no more than 2 charges can be activated (if a point is taken by three heroes, then the charge will be taken from two, and the progress will be interrupted in the third), thus, the point must be activated several times in a row.
So:
2:00 - Timer 30 seconds for C
2:30 - Activate point C for 1:30 minutes
3:30 - End time of objective C
4:30 - Timer 20 seconds for D1 and D2
4:50 - Activation points D1 and D2 for 1:00 minutes
5:50 - Completion of D1 and D2
6:20 - Every 3 minutes, starting at 6:20, points E1, E2, E3 and E4 are activated on the battlefield, which are valid for 0:40 seconds or until they are activated.
Each point E has only 1 charge. Activating point E launches one powerful catapult (mini-boss) on the nearest line, accompanied by 4 minions: a mage, a warrior, an archer and a assassin. This convoy moves along the line, destroying enemy defenses, and then stops at the final wall, and shoots to the citadel, causing 200 damage each shot, until catapult die, or until the enemy citadel destroyed. If two convoys meet at the line, they start a shootout - the catapult shoot to other catapult, and 4 minions attack the creeps, then attack other guards-minions, and then attack the enemy catapult.
7:00 - Timer 30 seconds for C
7:30 - Activation point C for 1:00 minutes.
And further in a circle.
At 11:00 a minute the gates H1, H2, H3 and H4 open, opening access to the regeneration spheres.
There are also Cells on the map - J1 and J2 - if the player enters the cell area and presses the switch - around him the restraints will come out of the ground for 4 seconds through which it is impossible to pass, but it is possible to shoot. For saving or chasing situations of pursuit. Cell recovery 15 seconds.
On the map there are also two simple camps F1 and F2, and two elite medical camps - G1 and G2, consisting of 1 medic and 2 melee and 1 ranged warrior. When minions G moves along the line, the medic heals the nearest allied units every 2 seconds for 20 health units, except for the catapult.
The winner is the team that previously destroyed the enemy’s citadel.
Thanks for watching!
