- Task Bar Hero giant fly is the Act 1 Stage 25 boss featuring high evasion and toxic poison attacks.
- Accuracy stats are critical to counter the boss's passive dodge rate.
- Priest class is the best support option to cleanse poison and sustain your party.
- AoE magic from the Sorcerer clears the summoned fly minions quickly.
- Cube upgrades should focus on Dexterity and Poison Resistance before the fight.
Task Bar Hero Giant Fly Location and Stats
The Task Bar Hero giant fly (known in-game as Vesper the Giant Fly) serves as the final barrier of Act 1, Stage 25. This boss is notorious for stalling progress due to its unique defensive mechanics. Unlike standard monsters, Vesper combines high evasion with rapid poison damage over time, making it a strict gear and composition check for idle setups.
To progress through the 4 difficulty tiers, your team must survive the toxic stings and land consistent hits. If your heroes lack accuracy, they will constantly miss, allowing the boss to slowly wear down your front-line tank.
| Boss Attribute | Base Value (Normal) | Special Combat Mechanic |
|---|---|---|
| Location | Act 1, Stage 25 | Final boss of the first Act |
| HP Pool | Moderate | Regens health when dodging attacks |
| Attack Type | Rapid Physical / Poison | Inflicts Poison DoT on target |
| Evasion Rate | 45% Base | Increases by 15% when HP drops below 30% |
| Minion Summon | Every 20 seconds | Summons 3 Larvae with high attack speed |
If your party's average Accuracy rating is below 120, your physical attackers will miss over half of their strikes. This triggers the boss's passive health regeneration, dragging the fight out until your tank collapses.
Before attempting this boss, players should ensure their game is fully updated. Recent hotfixes, such as Version 1.00.04, resolved critical display bugs regarding healing values and skill prerequisite checks, which directly impact survival during long boss encounters.
Best Party Builds and Class Counters
Defeating the Task Bar Hero giant fly requires a balanced formation. Since the game runs as a compact idle RPG on your desktop taskbar, your party must be self-sufficient and capable of handling both single-target bosses and summoned minion waves without manual intervention.
Using the right class synergy is the easiest way to overcome the evasion barrier. The table below outlines how each available class performs in this specific boss encounter.
| Class Name | Type | Performance Rating | Role in Giant Fly Fight |
|---|---|---|---|
| Knight | Free Base | ★★★★☆ | Absorbs toxic stings, protects backline |
| Ranger | Free Base | ★★★☆☆ | Sustained physical DPS, needs Accuracy gear |
| Sorcerer | Free Base | ★★★★★ | AoE magic damage, ignores base evasion |
| Priest | Free DLC | ★★★★★ | Crucial healer, cleanses poison debuffs |
| Hunter | Paid DLC | ★★★★★ | Premium single-target DPS, high base Accuracy |
| Slayer | Paid DLC | ★★★☆☆ | High physical burst, vulnerable to poison |
Always deploy the Priest in your second or third slot. The Priest's Blessing of Warding (fixed in Version 1.00.05) provides a shield that absorbs incoming physical stings, giving your damage dealers time to clear the summoned minions.

Step-by-Step Defeat Strategy
For players struggling to clear Act 1, Stage 25, following a structured progression path is essential. Use this step-by-step strategy to optimize your idle setup before facing the Task Bar Hero giant fly.
Claim and Deploy the Free Priest DLC
Go to the Steam store page, add the free Priest Class DLC to your account, and relaunch the game. Open your Hero Menu, select Formation, and deploy the Priest. This class is mandatory for surviving the boss's poison damage.
Equip Dexterity and Accuracy Gear
Review your Stash. Equip your Ranger or Hunter with weapons and accessories that grant flat Accuracy or Dexterity. Even Common or Uncommon gear with high Accuracy is better for this fight than Legendary gear with useless stats.
Tune Your Cube System Customization
Open the Cube System. Select the Synthesis or Inscription menus to reroll secondary stats on your primary weapons. Aim for at least one Accuracy roll on your main damage dealer's weapon.
Execute the Idle Fight Loop
Let the game run on your taskbar. Watch the first encounter to monitor your tank's health. If the Knight dies before the boss reaches 50% HP, return to earlier stages to farm gold and upgrade your armor.
If you experience any issues with purchased DLC classes or items not showing up, click the Mail icon in the top-right corner of the screen and press Refresh. This forces a sync with the Steam Item Server.

Cube Customization & Gear Requirements
To reliably farm the Task Bar Hero giant fly on higher difficulty tiers, you must optimize your gear using the in-game Cube System. The Cube allows you to customize item stats, perform Alchemy, and engrave powerful runes onto your equipment.
With over 500 unique items in the game, managing your storage is crucial. If you run out of space, consider purchasing the 3 Stash Pack DLC to expand your inventory for runes and rare drops.
| Gear Slot | Recommended Stat | Target Priority | Cube Action |
|---|---|---|---|
| Weapon | Flat Accuracy / Dex | High | Inscription |
| Chest Armor | Poison Resistance | High | Engraving |
| Ring / Amulet | HP Regeneration | Medium | Crafting |
| Shield (Knight) | Block Chance | Medium | Decoration |
During Steam platform maintenance or item-server instability, certain Cube actions like Alchemy or Inscription may be temporarily restricted. Always check the official Steam announcements page for live status updates.

Frequently Asked Questions
Q: Why does my team keep missing the Task Bar Hero giant fly?
The giant fly boss has a high base evasion rate of 45%. If your physical attackers do not have sufficient Accuracy or Dexterity stats, their attacks will miss. Consider using the Sorcerer class, as magic attacks ignore basic physical dodge rates.
Q: How do I stop my tank from dying to the poison damage?
You must deploy a Priest in your formation. The Priest cleanses poison debuffs and provides essential healing. Additionally, use the Cube System to engrave Poison Resistance stats onto your Knight's chest armor.
Q: Can I beat this boss using only the free base classes?
Yes. A free-to-play party consisting of Knight, Ranger, and the free DLC Priest can easily defeat the boss once you equip them with basic Accuracy gear from Act 1 farming.
Q: My purchased DLC class isn't appearing in my formation menu, what should I do?
Relaunch the game to force a Steam license check. If it still doesn't appear, open the in-game Mailbox from the top-right menu, wait 10 seconds for the Steam sync to complete, and click the Refresh button.
Once you defeat the giant fly, you can set your taskbar window to auto-farm Stage 25. This is an excellent spot to farm early-game Soulstones and Uncommon gear before pushing into Act 2.
