How to Get Free Sundering Steel Weapon in Arknights Endfield
The 5-Star weapon Sundering Steel is guaranteed within 10 draws from the Supply Hub. Here's the step-by-step process:
Earn Special Supplies
You need Special Supplies to make draws at the Supply Hub. Each draw costs 900 Special Supplies. You can earn supplies in several ways:
- Daily deliveries from Special Ops Teams (600 supplies per team at 4:00 AM UTC+8)
- Completing one-time missions
- Completing daily missions
Unlock Special Ops Teams
You start with Team Dijiang unlocked by default. To maximize your daily Special Supplies, unlock the other two teams:
- Team Valley IV - Unlocked by pre-registering for Arknights: Endfield
- Team Wuling - Unlocked by inviting 1 friend to assist
With all three teams unlocked, you'll receive 1,800 Special Supplies every day (600 per team).
Make draws at Supply Hub
Once you have 900 Special Supplies, head to the Supply Hub and make a draw. The guaranteed pity system works like this:
- Each draw costs 900 Special Supplies
- If you don't get Sundering Steel in your first 9 draws, your 10th draw is guaranteed to be the weapon
This means you'll definitely get the 5-Star Sundering Steel weapon within 10 draws maximum. You can equip the Sundering Steel weapon on Sword- type operators in Arknights Endfield.
Items you draw are stored in the Depot. You can select up to 5 items to move into your Backpack. After you've added Sundering Steel to your Backpack, click the Claim button to receive it via in-game mail once the game officially launches.
Important: You can only claim Backpack items once, so make sure you've selected everything you want before clicking Claim.
