What it is
- Face players from all over the world in real time, at any hour.
- Big rewards at the end of the season, by rank.
On Foundry
- On Foundry, it opens on 10 December after the maintenance (Korean time), against Foundry players only at first.
- Until 31 December, the Arena earns event points to get ready:
- 20 a win, 10 a battle, 5 a win against an NPC.
In battle
- No Guardians and no Defenders.
- A battle that drags on brings Battle Frenzy.
- Every hero deals more damage, while healing and max Health go down.
Ban, pick, exclude
- Each player bans 2 heroes neither side may use.
- Out of time, your last bans apply; with none, random 5★ heroes.
- A random player picks first, then you pick two by two in turns.
- Never the same hero as the opponent.
- With 5 heroes each, each excludes one of the other's five; the four left fight.
- Last, place your heroes; out of time, they keep their current spots.
Preban protection
- Preban protection shields the hero in your third slot from the opponent's ban.
- Not in Draft Arena, nor in some Arena modes.
Support heroes
- Some heroes are lent to Heirs with few heroes or little gear, owned or not.
- Only below the Champion league, in Ranked battles.
War rules
- From the Champion league up, in Ranked battles, special rules are drawn at random for the match.
- They show before the bans.
- The season's war rules are listed in the World Arena lobby.
Points decay
- From the Gold league up, without a Ranked battle for a while, your victory points drop by 2%.
- After 7 days in Gold, 3 days from Master up.
- Then 2% more at the same interval. A message warns you before.
Friendly battles
- Form or join a group to fight friends, guildmates or other Heirs.
- It never touches your rank or victory points.
- Set and Match: several sets, prebans that add up, up to 16 heroes banned.
- Lunatic Draft: up to 38.
- Also a Draft mode with preset heroes, and a mode with one hero per class.
Replays
- Replays play from the battle log, turn by turn, on the device the battle was played on.
- In a guild, share one in guild chat: it stays watchable for 15 days.
World Arena Tournament
- 16 players fight for the win: a group stage in groups A, B, C and D.
- Then the group winners play the deciding matches, semi-finals and final.
- Press Register during the tournament to find an opponent.
- In the waiting room, Ready cannot be undone; the battle starts after a countdown.
- Out of time, the winner is decided by Health left (%).
- Then by heroes alive, then by total damage.
- Giving up or leaving loses the match.
- If the opponent leaves or drops, it can end without a battle: a win by forfeit.
- Watch any match marked LIVE once eliminated; still in, once your own match of the round is over.
The Pantheon
- Each regular season's top 3 are listed there for good.
- The E7WC and E7 Masters tabs keep the official tournaments' champions.
