How to Get 777,777 Free Unstable Cores & a 300 Power Level Boost in Destiny 2

Bungie rolled out a short-term catch-up chest in the Tower that gives every account a one-time stack of 777,777 Unstable Cores plus a catch-up gear package that can bring low-power accounts up to 300 Power. This was explicitly intended as a temporary, goodwill measure while Bungie moves to remove Unstable Cores from the game.

Why this happened

Bungie introduced Unstable Cores as a new infusion currency in the Edge of Fate expansion. Players quickly complained the currency made upgrading multiple builds prohibitively expensive, prompting Bungie to announce a plan to deprecate the mechanic and move infusion back to Enhancement Cores + Glimmer. As a temporary measure they put a one-time catch-up chest in the Tower that hands out 777,777 Unstable Cores so players won’t be blocked while changes land.

What You Get from the Catch-Up Chest

• 777,777 Unstable Cores — one-time, account-wide reward in a catch-up chest.
• Catch-up gear that can get players to 300 Power (a set of Tier 3 armor/weapons and Enhancement Cores to bring recipients up to ~300 Power). Multiple outlets and the official post confirm the chest also includes gear to set players to 300 Power.
• Claim window & expiry — Bungie framed this as a short-term fix during the transition; sources report the items (and the cores) are intended to be used before the seasonal deprecation (news coverage and patch notes noted the one-time distribution around mid–Oct 2025). Always check the in-game tooltip for exact expiration.

Step-by-Step: How to Claim Your Free 777,777 Cores & Power Boost

1. Enter the Tower
   • Log into Destiny 2 on the character you want to boost.
   • Go to the Tower Courtyard (social hub).
   • Walk over to where Commander Zavala stands (Vanguard area).
2. Locate the “Techsec Supply Drop” chest
   • Right near Zavala you’ll find a chest labelled Techsec Supply Drop.
   • The icon appears like a Vanguard-sanctioned container.
3. Interact with it
   • Approach the chest and press the “Interact” button.
   • A “Caution” screen pops up warning that it will advance your Power/gear.
   • Accept the prompt to open.
4. Claim the rewards
   • After opening, you’ll receive:
     • 777,777 Unstable Cores (one-time per account)
     • A full set of catch-up Tier-3 gear (weapons + armour) capable of boosting you to ~Power 300 if you’re below that.
   • Make sure to spend the Unstable Cores and use the gear, since the currency is being deprecated.
5. Use your upgrade materials
   • Use the gear to reach ~Power 300 (if you haven’t already).
   • Apply the Unstable Cores where you need them most (infusing key weapons/armour you plan to keep).
   • Since Unstable Cores will be removed, prioritize builds you intend to stick with.
6. Be aware of catch-up conditions
   • The chest is once per account (not per character).
   • The “Caution” screen warns that players under a certain rank or new to the game might find high-difficulty content if they open too early.
   • The offer is linked to the current season (until the end of Season 27) so claim it soon.

What’s Inside the Catch-Up Chest — Full Breakdown

Reported contents across coverage and community guides include:

• 777,777 Unstable Cores (one-time).
• A full catch-up gear package: weapons and full armor set at/near 300 Power, plus Enhancement Cores (sources listed exact example weapons/armor in their guides).

(Exact item names can vary by platform/account — check the in-game loot screen after claiming.)

Understanding Unstable Cores — and How to Use Them Effectively

• Infusion above soft cap: Unstable Cores are used for infusing gear above the soft cap (the new Seasonal Power Bonus range). If you want to push a weapon or armor piece above 200 PL into the seasonal/300 range, that’s where cores are spent. Guides and Bungie notes explain the separation between Enhancement Cores (below soft cap) and Unstable Cores (above).
• Spend on builds you’ll keep: because the system is being deprecated, spend cores on the few pieces you actually plan to keep or experiment with now (don’t blindly infuse every weapon/armor). Community posts and official feedback warn the economy was stingy — this windfall is the moment to make planned upgrades.
• Dismantle high-bonus drops for more cores: if you need to top up after using the catch-up stack, dismantling Seasonal Bonus gear yields Unstable Cores (higher bonus → more cores). Several community guides detail dismantle math (approx formula varies).

The 300 Power Level Boost — How It Works

• The catch-up chest includes a package calibrated to bring recipients to ~300 Power (Tier 3 armor/weapons + Enhancement Cores). For players below 300, equipping these items and applying the included Enhancement/Unstable Cores will instantly raise overall Power to about 300. This has been explicitly mentioned in the official update notes and multiple walkthroughs.

Smart spending plan (what to do with 777k cores)

1. Prioritize a single PvE and a single PvP set — max one armor set and a handful of weapons for activities you plan to play. Infusion is expensive per piece; focus on impact. (Community consensus.)
2. Infuse raid/seasonal weapons first — weapons you use often give the best return on infusion investment.
3. Don’t forget mod synergy — before you infuse, plan which mods you want on the piece so you don’t waste cores on a build you’ll immediately swap. (Player guides emphasize build planning.)
4. Reserve some cores for experimentation — even though the system will be retired, experiment with one or two throwaway builds if you enjoy trying mechanics — but avoid infusing your entire vault. (Community advice.)

Important Warnings & Deadlines

• One-time: The 777,777 distribution is one-time and account-wide. Don’t assume it will come back.
• Deprecation coming: Bungie has publicly said Unstable Cores will be deprecated and replaced with a simpler infusion cost model (Enhancement Core + Glimmer). Plan to spend cores you actually need now; Bungie’s changes may convert or remove the currency later.
• Check in-game tooltips: expiration dates and exact claim rules may appear in the in-game item tooltip or Bungie’s TWID/patch notes — always double-check.

Quick FAQ

Q: Is this claim per character or per account?
A: Per account (one-time).

Q: Do the cores expire?
A: News and guides indicate they’re intended to be used before the seasonal deprecation; confirm in the in-game tooltip for exact expiry.

Q: Will Bungie convert unused cores later?
A: Bungie said they will deprecate the currency and move infusion back to Enhancement Cores + Glimmer; details about converting leftover cores were not guaranteed—spend what you need.

Final takeaway

This one-time giveaway is Bungie’s short-term fix to unblock players while they remove a widely unpopular currency. Claim the chest in the Tower, equip the catch-up gear to hit 300 Power if you need it, and spend your cores thoughtfully — prioritize the few pieces you’ll actually use before the system is changed.
