[Hero Wars] Cosmic Battle BAN

Cosmic Battle Overview

  • A Cross-Server PVP Event

Event Flow

  • In the 24-hour preparation phase, every player casts their votes for heroes in each league. Unlike before, you now have 7 voting rights, but the voting is role-restricted.
  • The top 10 heroes with the most votes will be temporarily prohibited for use exclusively within this event.
  • Concurrently, cross-server player versus player battles will commence along with the event.
  • Unlike in other PVP events, you fight with your current power, but you won’t have the option to select heroes that were prohibited in the voting phase (which may pose a disadvantage for those who primarily focus on renowned heroes like Dante).
  • Points accumulate for successful attacks or defenses in player versus player matches.
  • Utilize these accrued points for purchases at the event store.
  • Additionally, there’s a standard quest known as the “The Pass of a Warrior” available alongside.

Difference from the first event

  • The event duration is now nearly half as long.
  • The quest content has been revamped.
  • The points required for league promotion have seen a significant increase.
  • Winning and ranking rewards have been substantially elevated. Store pricing remains consistent, resulting in a more streamlined approach to efficiently reward players in a shorter timeframe.
  • The cost of emeralds needed to purchase battle counts has been raised. In comparison to the previous event, this one can be considered higher risk, higher reward. Nonetheless, the maximum amount is approximately 100 emeralds cheaper. This is a significant benefit for those aiming for high rankings, without consideration for cosmetics.
  • Change opponents by using emeralds.
  • The best available Heroes vs. has been introduced.

Official Message

The previously announced PvP event “Cosmic Battle” will start this Friday — for 3 days, all players with team level 40 or higher will have the opportunity to battle against players within the same platform, using their heroes at their current power!

For victories and successful defenses, you will earn Ranking Points and Cosmic Battle Coins. The higher your rank is, the more Coins you get – it’s that simple! As usual, you’ll be able to spend the Coins on equipment items and other useful resources in the Event Store!

And tomorrow, the first stage of the “Cosmic Battle” starts in the game — the Hero Ban phase! You will decide which Heroes will be banned from the “Cosmic Battle”. Here’s how it works:

  • For one day, you will be voting for one hero from every game Role (such as Tank, Healer, etc.) you want to ban from the ”Cosmic Battle”;
  • Once the Ban phase is over, 10 Heroes (3 Heroes of the Mage role, 2 Heroes of the Tank role, and 1 Hero from each of the remaining roles) with the most votes against them will be excluded from participating in the ”Cosmic Battle” — players won’t be able to use them either in attacking or defending teams;
  • The hero ban system only applies to the “Cosmic Battle” event — you can continue to play with any heroes in other modes.
  • We have made changes to the Cosmic Battle matchmaking system. Now teams are more accurately matched according to your power level. (For example, pet power is now taken into account as well). Additionally, due to numerous requests, we have added the ability to refresh opponents.

The Pass of a Warrior

Voting Phase

  • Select 7 heroes within the 1day timeframe.
  • If you have multiple accounts, you can vote with each one.
  • Since each participant has only one vote, it’s possible for heroes favored by top-tier players as well as those popular among newer players to be chosen.
  • Once you’ve voted, you can view the vote tally until the game commences.
  • You can strategize your offensive and defensive formations while observing the voting phases.

The Rules of the Cosmic Battle Run-Up

General Information

  • The Run-Up to the new event is here! The new event will be a cross-server arena for the players who set up their defense team on the main event screen.

The purpose of the Run-Up

  • This stage gives our community the chance to decide which Heroes will be part of the event. Once the Run-Up is over, we’ll ban the 10 Heroes that get the most votes. Among the 10, there will be 3 Mages, 2 Tanks, and 1 Hero for each of the other classes.
  • You’ll have one day to vote the Heroes you don’t want out of the event.
  • In this event, players get to shape the Hero lineup. Everyone can pick 1 Hero they personally don’t want there for every class.

The Main Event

  • Your Heroes will join the battles at their current power. You can always power them up to give your team a better fighting chance.
  • The battles will earn you points and event coins. Points determine your standing in the event rankings, which let you earn more coins as you progress. You can use those coins to get some unique stuff from the event shop.

Final Vote Results

  • You can view preliminary results in real-time mode as the voting goes on. Final results will be announced at the end of the Run-Up.
  • In the end, we will ban the 10 most voted-for Heroes from the event. Among the 10, there will be 3 Mages, 2 Tanks, and 1 Hero for each of the other classes. If there’s a draw between the 10th and 11th places (or lower ones), it will be settled by random selection.
  • You’ll still be able to play the banned Heroes in other modes-they just can’t be part of any attack or defense teams in this event.

Player vs. Player (PvP)

Crucial Aspects of PvP

  • Success rates in both attacking and defending are of equal importance.
  • Achieving successful defenses against certain top-tier players can be challenging, but such opponents are a minority. It’s advisable to consider defensive strategies that the majority of players cannot easily overcome.
  • Consecutive win rewards are available.

What to do when you can’t win in PvP battles

  • 1. Invest in Jorgen.
  • 2. Try developing other heroes as well.
  • 3. Lower the rank tier of your opponents. By weakening your defense and observing the situation, you can match up against weaker opponents.

  • Utilize emeralds to buy additional attack chances daily, maximizing your progress.

2. Maximizing Rewards Style

  • During the initial two days, adjust your defense to a weaker setup, lower your league, and earn rewards through consecutive victories.
  • On days 1 and 2, the plan could be to win consecutively to secure a reward and then deliberately lose consecutively, but this does not seem to work very well.
  • On the third day, optimize your defense and aim to secure ranking rewards.
  • On the third day, depending on the situation, consider purchasing additional attack chances with emeralds (budget 800 emeralds).

3. Defense-Focused Style

  • If you have limited time to participate in the event, prioritize setting up your defense early.
  • Raise the league to the point where a match can be made.
  • Exchange ranking rewards for desired items in the shop. Gradually receive rewards for successful defense after the event, one by one.
