Mods — Items, Armour & Drops — Rebellion

Last updated: 2026-10-10How to add your own item, armour or key-activated item to Rebellion, have the smith forge it and put it into mob drops.

Items, Armour & Drops

Everything in the bag that is not a weapon is an entry in the gear section of balance/items.synx. The same file has the drops section — who drops what. An item's icon is assets/items/<id>.png, its texts are gear_<id>, sum_<id>, desc_<id> (Images, Textures & Text).

1. A simple item

synx
gear
  bent_blade
    slot item
    rarity common
    price_souls 35
    stats
      crit_chance 0.03
FieldWhat it does
slotitem — a passive item in the bag; armor_top, armor_bottom — upper and lower armour; active — a cross (the F key)
raritycommon, rare, super_rare, legendary, mythic. Until the player unlocks legendary and mythic items in the Reliquary, they do not drop for them
price_soulsPrice at traders, souls
statsModifiers while the item is in the bag: 0.03 — +3%. All 14 are in the reference
effectsSpecial actions: lifesteal, thorns, shield, ignite, aura, key action… — also in the reference
sidesaint or demon — an angelic or demonic item. For a player of the same faith all its bonuses are stronger (up to +50% at the highest faith stage), for the opposite faith weaker by as much
recipe, recipe_soulsWhat the smith forges it from and for how many souls

2. Armour

Armour is the same entry with the armor_top or armor_bottom slot. Its main modifier is absorb, the share of damage it soaks up. A player's total absorption is capped at 60%.

synx
gear
  bone_plate
    slot armor_top
    rarity rare
    price_souls 160
    stats
      absorb 0.06
      max_hp 12
    effects
      resist_demon 0.04

3. An item with a special action

effects is the block of special actions. For example, lifesteal and ignite:

synx
gear
  ember_fang
    slot item
    rarity rare
    price_souls 140
    effects
      lifesteal 0.04
      ignite_share 0.3
      ignite_sec 3

A key-activated item is a plain item (slot item) with an effects.active block; it fires with the key of its item slot (3–6):

synx
gear
  iron_vow
    slot item
    rarity rare
    price_souls 180
    effects
      active
        kind buff
        cooldown_sec 45
        sec 8
        stats
          absorb 0.2

active kinds: buff, aegis, mend, nova, stasis, recall, trim — what each does is in the reference.

4. The smith's recipe

synx
gear
  claw_charm
    slot item
    rarity rare
    price_souls 120
    recipe
      - bent_blade
      - imp_horn
    recipe_souls 40
    stats
      crit_chance 0.06
      crit_damage 0.1

The smith takes the listed items and recipe_souls souls. Components can be the game's items or your own.

5. Mob drops — drops

synx
drops
  exploder
    chance 0.11
    items
      - imp_horn
      - bent_blade
  • The key is a mob id from the game's balance/mobs.synx.
  • chance — chance per kill to drop one item, 0…1; it is picked evenly from items.
  • items is a list, and a list is replaced whole. If the mob already drops something in the game, repeat it in your list, or the mob stops dropping it. Karambit does this: the exploder dropped an imp horn at 5%; the mod keeps the horn and adds the blade with a total chance of 11%.

Room chests, treasure rooms and bosses are the chest, treasure_chest, boss_chest and mini_boss_chest sections of the same file: change them the same way, with fields from the game's file.

6. Change a game item

The same key and only the fields you change:

synx
gear
  war_drum
    price_souls 90
    effects
      aura_radius_m 14
