Ancient Maze

How it Works

Given its unique nature in comparison to other Archero events, it can be difficult to fully understand what's going on. Here is the basic rundown:

1. Upon entering the event (cost = 15 energy), you'll notice your stats are massively reduced. Your gear does not take effect in this mode, but your weapon time will remain as selected as will your hero. It's not entirely clear what upgrades take effect but current theory suggests your hero stats plus some other upgrades like talents and all perks.
2. Upon clearing each room (100 in total), you'll choose one of 2 or 3 portals to take to your next room. Current theory is that the portal color represents easier or more difficult options for more or less loot as indicated by the biomes and the rarity color to the portal. This isn't proven yet. These portals can be:
   • Green: Features often simpler rooms and enemies from the biomes in the first chapters
   • Blue: Features rooms and enemies from the biomes in the early to mid-game chapters
   • Purple: Features often more complicated rooms and enemies from the biomes in the later chapters
   • Orange with fire: Features a positive room, often a room of loot chests or free upgrades -- always take this one if you can! It appears in level 14, 24, 34...
3. Every 10 level, you will fight a boss...
4. After beating the run, the difficulty selector will be enabled, allowing you to pick a harder difficulty for higher rewards. For example, the 2nd difficulty introduces boss monsters like hero mode. Take note though, as of the release of 2.5, this feature seems to be bugged. The higher difficulties are selectable, but they still have the lock icon appear on them as if they weren't.
5. You'll accrue a new currency called ancient silver. Randomly throughout the run you'll be made offers to purchase in-run upgrades for ancient silver. You'll only be able to purchase 1 item when presented with a choice. Furthermore, any ancient silver not spent by the end of a run will be collected as a reward for future runs. Three merchant will appear
   • Equipment Merchant: against some ancient silver, you will be able to purchase pieces of gear (weapon, armor...) you'll wear for the duration of the run: 3 ancient silvers = Great object (green), 6 ancient silvers = Rare object (blue), 12 ancient silvers = Epic object (purple), 36 ancient silvers = Legendary object (gold)
   • Chef??: for food items that grant buffs for the fun such as:
     • Spaghetti: Crit Rate +7%
     • Burger: Max HP +15%
     • Kimchi: Attack Speed +15%
   • Magician: will sell you some abilities (Cost in ancient silver)

Reward Structures

Rewards for this mode include:

• Soul Stones
• Ancient Silver
• Evolution Chips
• Sapphires

Ultimately this makes it the place to go to level up your heroes, and the primary source of soul stones to be used to purchase hero shards. While ancient silver can be used mid-run, it is possible to take ancient silver out and keep it, and it's worth noting that it may be useful in the future for other things. Lastly, it drops more soul stones per energy than its predecessor so if you're looking to evolve heroes be sure to play this event.
