Bit Heroes Quest: How to Beat Grimbora in Z7D3

To defeat Grimbora in Zone 7 Dungeon 3 (Z7D3) of Bit Heroes Quest, you must enter the boss encounter with a full Skill Point (SP) bar, use a dedicated tank to absorb Grimbora's heavy physical attacks, and focus your initial burst damage on the supporting minions before shifting to the boss.

Recommended Team Formation

Grimbora deals heavy direct and cleave physical damage. Running a fragile build in the front row will cause an immediate wipe. Organize your party based on your character's role:

• Frontline Slot (Tank): Use a high-stamina familiar with block, deflect, or evade traits. A fully stabled (+5) Shrampz or an upgraded Ulairius provides the durability needed to soak single-target spikes and deflect damage back to the enemy.
• Middle Slot (Damage Dealer): If your hero uses a standard DPS build, place yourself in the center. This position avoids direct frontline hits while maintaining steady offensive output across all phases.
• Backline Slot (Healer or Sustained Support): Position a reliable healer in the rear. Remmyt is the ideal choice for Zone 7 due to higher baseline stats, critical heal scaling, and shields that buffer the frontline against consecutive attacks. Bor'lan can serve as an accessible budget alternative if Remmyt is unavailable.

If your hero is built as a primary tank, take the front slot yourself and run two high-output DPS and healing familiars behind you.

Pre-Boss Preparation and SP Management

Most failed attempts occur because the party enters the boss room with empty SP meters. Without banked SP, your healer cannot cast emergency shields and your damage dealers cannot immediately burst down enemy adds.

1. Charge SP on Trash Mobs: Before stepping onto the boss tile, fight weaker dungeon trash using only basic attacks. Turn off auto-combat to prevent familiars from wasting SP on low-health enemies until your team reaches 100% SP.
2. Time Dungeon Shrines: Clear the map to locate shrines before engaging Grimbora. Collect damage or speed shrines immediately before initiating the boss fight, and save healing shrines for recovery after difficult elite encounters.
3. Prepare Consumables: Keep minor or regular potions equipped on your hotbar to stabilize your tank between healer turn cycles.

Combat Priority and Boss Strategy

Execute the encounter in two distinct phases:

1. Eliminate Minions Immediately

Grimbora’s supporting minions inflict debuffs, crowd control, and sustained focus fire that quickly overwhelms your frontline. Spend your banked SP on turn one to cast high-damage, single-target skills directly at the most dangerous minion. Do not split damage across multiple targets; eliminate them one by one to reduce incoming damage per turn.

2. Manage Sustain Against Grimbora

Once the adds are dead, all enemy pressure shifts to Grimbora alone. Your healer can generally sustain your frontline through standard attacks. However, watch your tank's health closely:

• If your frontline tank drops below 30% health and your healer's turn is not next in the action queue, manually use a potion on the tank.
• Maintain defensive buffs or shields whenever Grimbora queues a heavy physical attack.

Gear and Total Stat (TS) Requirements

If your team wipes despite executing this strategy correctly, your hero likely lacks the Total Stats (TS) required for Zone 7. Familiars inherit their combat statistics as a percentage of your hero’s TS, meaning low player stats directly weaken your tank and healer.

• Prioritize Tier 7 Epics: Fully upgrade a complete set of Tier 7 Epic gear before attempting Z7D3.
• Avoid Un-upgraded Legendaries: A fully upgraded Tier 7 Epic provides higher TS than an un-upgraded or partially upgraded Legendary, while requiring significantly fewer rare upgrade materials.
• Farm Previous Dungeons: If you cannot survive Grimbora's baseline hits, spend your energy farming Z7D1 and Z7D2 to collect upgrade materials and finish maxing your Tier 7 equipment.
