Into The Hive Mastery: Blast Grenade Slots and Booster

Blast Grenade’s Slot 2 unlocks at Mastery 4, and Slot 3 unlocks at Mastery 8. Slot 1 is shown as an Empty Slot. Mastery Booster is advertised to double Mastery XP for every weapon and piece of equipment, while halving the Cash and ore required for every equipment upgrade.

These thresholds belong to Blast Grenade. Use them when checking its augment slots rather than treating them as requirements for every piece of equipment.

Finding Blast Grenade’s augment slots

In the INSTALL AUGMENT interface, choose Blast Grenade from the throwable selection, then choose one of its slots. Selecting the grenade opens its AUGMENT SLOTS panel, where you can distinguish an empty slot from the slots displaying mastery requirements.

The selected-slot panel identifies the destination with wording such as INSTALL INTO Blast Grenade – SLOT 1. Its INSTALL AUGMENT instruction describes moving the Augment from your inventory into that selected slot. This makes the selection order useful: choose the throwable first, then the slot that will receive the augment.

For planning Blast Grenade’s additional slots, Mastery 4 is the threshold attached to the second slot, followed by Mastery 8 for the third. Slot 1’s displayed state is simply Empty Slot; that label describes the slot’s contents rather than naming another mastery threshold. See the augments guide for related augment information.

What Mastery Booster affects

Mastery Booster combines two advertised benefits:

• Double Mastery XP on every weapon and piece of equipment.
• Half the Cash and ore cost for every equipment upgrade.

The XP benefit applies across weapons and equipment, so its advertised scope extends beyond Blast Grenade. The upgrade benefit concerns the resources required when upgrading equipment: both the Cash requirement and the ore requirement are halved.

These benefits address different parts of progression. One increases Mastery XP gains; the other reduces equipment upgrade spending. If you are considering the pass for mastery, the upgrade discount is an additional part of the same purchase. The listing describes Mastery Booster as permanent and lists its price as R$199. The Mastery Booster guide covers the pass specifically.

Mastery XP and VIP’s Rank XP bonus

Keep the XP names separate when comparing passes. Mastery Booster advertises double Mastery XP, while VIP advertises +25% Rank XP. Those bonuses refer to different progression measures.

For the Mastery XP benefit discussed alongside Blast Grenade’s mastery requirements, Mastery Booster is the pass advertising that bonus. VIP’s advertised XP bonus is tied to Rank XP. See the Rank XP guide for that side of progression.
