From Scratch

Overview

From Scratch is a "lite roguelike" growth challenge mode.
You must enter naked. The system randomly issues a set of starting gear, then you snowball by collecting drops from killing enemies.
Enemies grow stronger each wave and carry random gear. You need to adapt on the fly based on the resources you obtain.

Entry Requirements

Naked: Cannot wear any equipment; backpack and pet bag must also be empty.
Carry a BossRush Ticket.
Cannot carry a Faction Banner or Bloodhunt Transponder (otherwise you will enter a different mode).

Starting Gear

The system randomly issues the following gear at the start:
Weapon (100%): Quality 1-3, random attachments (roughly 30% chance per slot).
Ammo (100%): Matching weapon caliber, 120-180 rounds, magazine pre-loaded.
Armor (50%): Quality 1-3.
Helmet (50%): Quality 1-3.
Melee weapon (40%).
Backpack (40%).
Medical supplies (100%): 3 healing items.
Totem (30%).
Mask (30%).

Wave Structure

From Scratch uses an unlimited wave system with enemy types progressing by wave:
Waves 1-2: Weakest grunts only (low HP, no ghosts), 0 Bosses.
Waves 3-5: All grunts (no ghosts), 0 Bosses.
Waves 6-10: Grunts + Bosses (no elite Bosses), 1 Boss.
Waves 11-15: Grunts + Bosses, 2 Bosses.
Waves 16+: Full enemy pool + full Boss pool, 2+ Bosses.
Each wave spawns 3 enemies by default (adjustable to 1-10 in config).

Enemy Gear

Enemies in From Scratch don't come empty-handed — they also carry random gear.
Gear quality scales with wave and enemy HP: Quality = 1 + (Wave/5) + (HP/500), max 6.
Enemies carry weapons (with random attachments), melee weapons, ammo, and multiple random items.
Boss-type enemies retain their original helmet and armor.
All this gear drops in loot crates after killing enemies.

Difficulty Scaling

Enemy health +3% per wave (cumulative).
Enemy gear quality also increases as waves progress.
Later waves feature all Bosses, including custom Bosses.

Wave Intervals

By default, the next wave starts automatically on a countdown (interval is configurable).
You can also manually trigger "Rush Next Wave" via the signpost (must enable manual mode in config).

Arena NPCs

Awen (Courier): Always present, provides item storage and retrieval services.
One of Dingdang or Yuori (random): Provides Reforge/shop or healing services (married NPCs are excluded from the random pool).

From Scratch — Complete 10 waves (bonus 30,000).
Perfect Scratch — 5 waves without taking damage (bonus 350,000).

Strategy Tips

Starting gear is completely random. Use whatever you get; don't fixate on a "perfect start."
The first 5 waves have no Bosses. Use this time to scavenge gear upgrades from grunts.
Enemy gear quality increases with waves. Later grunts may drop better gear than what you have.
Medical supplies are a scarce resource. Minimize unnecessary damage.
