Idle Heroes Tower of Oblivion Guide: Climbing With Counters and Patience

The Tower of Oblivion is Idle Heroes’ climbing challenge. Each floor is a fixed battle, and clearing it gives rewards and shows how far your team has come. Progress is permanent, so every floor you clear is a step forward.

How it works

• Floors get steadily harder.
• Each floor has a fixed enemy team.
• Clearing floors gives rewards, often including useful materials.

Because enemy teams are fixed, you can study them and plan your line-up.

Reading the enemy team

Before attacking a floor:

1. Check the enemy factions – bring heroes with faction advantage.
2. Look at their front line – a tough front may need more damage or armour-breaking effects.
3. Spot dangerous back-line heroes – plan control to stop them.

See our factions and team building guide for how faction advantage works.

Building tower teams

• Use faction counters, even if it means swapping in a slightly weaker hero.
• Check the aura – changing heroes can change your team bonus.
• Keep a healer for longer fights.
• Add control against teams with strong ultimates.

Retry before upgrading

Battles include some randomness. If you lose narrowly:

• Try again a few times.
• Adjust positions – swap which heroes face the enemy’s strongest attackers.
• Change one hero to counter the biggest threat.

When to stop climbing

The tower doesn’t expire. When you hit a wall:

• Upgrade your core team with your daily resources.
• Focus on events and other modes for a few days.
• Come back after a meaningful upgrade.

Common mistakes

• Brute-forcing floors without checking factions.
• Forgetting the aura when changing heroes.
• Spending resources on random heroes just for one floor.

Climb with counters, retry close fights and come back stronger – the Tower of Oblivion rewards patience more than raw power. It’s a great complement to your daily routine.
