We are going to need Multiplayer for this, can be 6-12 months from now or any timeline that works.
The Guild Wars event will be throughout Overworld, Arena and Zero - IBG style 🤙.
As we saw from the trailer and tutorial lore, the planet is hostile. There is something lurking in the dark.
We have detected dimensional instability throughout our Regions. Something doesn't like us being here. The Leviathan scientists have came up with a plan to deploy 3 Pylons on each region, in order to stabilize the area and prevent a catastrophe that would probably kill everyone and remove any chance of leaving the planet
1st stage - Overworld. Random portals throughout each region appear, spawning Nightmare Illuvials going straight for our Pylons. They want them gone. The Nightmare Illuvials are tanky, move fast and run straight towards each Pylon, trying to destroy it. They will spawn in waves, each time increasing their number and strength. It can take 1-3 players attacking a single one, in order to defeat it before it reaches the Pylon. However Pylons should be under attack at a certain point, so it should be rather hard stopping every single one of them. Upon 100-0ing them, 1 player goes into arena to finish the job, the others help their War Party. We can repair the Pylons by infusing them with OW ores, higher tier/amount repairs higher % of HP. After defeating a Nightmare Illuvial, it will require a certain amount of energy to enter the arena mode and defeat it for good. That energy can be drawn from a pool for the whole party. Meaning, guilds participating in the event, must stockpile Fuel to defeat all the waves, and ores to repair the Pylon. Upon defeating the final wave in a Region, it stabilizes ->Stage2
2nd stage - Illuvium Zero. Only guilds that cleared stage 1 can participate here. After defeating the last wave, a huge boss spawns in the respective region in Illuvium Zero. We should be able to zoom out to the whole region by then and see where our land is located in that region. The boss would spawn in a random location. Each guild city sends their army chariot forward, attacking the boss, distance and time to reach will depend on location. We will use tens/hundreds of Illuvials packed into a chariot and not all of them are going to make it back. The boss will be insanely strong, our goal here is not to defeat it but to lower it's HP with our attacks. Each land will be able to send 1 chariot forward, which can be packed with other guild members' illuvials, or illuvials already bought and stockpiled for this reason. Upon fighting the boss and unable to defeat it, our chariot goes back and all illuvials are "wounded". A new Zero building, Infirmary, will be able to heal the wounded illuvials over a certain amount of time (can be sped up with credits), during which we can send the chariot back with a fresh squad of illuvials. Upon reaching the Infirmary's capacity, any illuvials hurt by the boss encounter will perish, unable to be recovered (burned). ILVZ f2p players/guild members can participate here by providing a staging point for attacks (their chariot) and also by healing wounded illuvials for the entire guild. The boss will be under attack from multiple guilds, the guild who did the most damage from the overall health pool, wins the event/region)->Stage3
3rd stage - Arena. After the first 2 tough battles, it's time to collect our personal rewards. It can be a simple 1-10 wave encounter, of Nightmare Illuvials or a new type, like boss Heralds. Upon defeating wave 10, you enter the boss encounter with whatever illuvials that survived the previous wave. The boss was already weakened in stage 2, so it spawns with 1% hp in this stage. It should be hard to defeat, but not super hard as this is supposed to be a more chill/reward phase. Upon defeating the boss, the player receives their boss loot. Can be legendary skins (different drop rates for different tiers), legendary gear, rare crafting materials, battleboards and so on.
