Abyssus Frag Grenade Mastery — 8 Casts in 5 Seconds
Use the Frag Grenade 8 times within 5 Seconds. Stock enough charges and cast them in a short burst to unlock Frag Grenade’s unique Forge options.
Use the Frag Grenade 8 times within 5 Seconds.
Reward: Frag Grenade Mods
Frag Grenade starts with three charges. Both Ability Abundance nodes and shared Extra Pockets give a documented route to eight charges without already owning grenade-specific Forge rewards.
Suggested loadout

- Ability
- Frag Grenade
- Aspect priorities
- Barrier (Defense)
- Weapon Forge priorities
- Large Capacity
- Ability Forge priorities
- Extra Pockets · Rich Get Richer
- Charm alternatives
- Freebie · Durable
Check fire-mode unlocks before the run. These are priorities to seek; drops are random. One Charm can be equipped by default, two with Charm Power. Forge selections also compete for expedition opportunities unless Artificer is unlocked.
Open this challenge in Build Creator →Attempt sequence
- Equip Frag Grenade and buy the relevant charge nodes if accessible.
- Take Extra Pockets at an Ancient Forge. Freebie and Rich Get Richer can support further casts, but Freebie is chance-based.
- Begin with charged ability stocks and throw eight times inside five seconds.
Why the challenge may not trigger
- Eight casts across an entire encounter do not satisfy the five-second window.
- Compact Grenade halves charges and is a poor fit for this objective.
- Do not use mastery-locked grenade upgrades as prerequisites for the first mastery completion.
If the ideal items do not appear
If the shared upgrade does not drop, use Freebie for an attempt or return on a later expedition. A failed random cooldown refund is not evidence of a bug.
Keep the exact in-game requirement separate from this suggested route. Compare the notification and Logbook after your attempt; the Creator checks your planned choices, not the live achievement.
