Water Protection

Water Protection is an armour enchantment Origins adds for the origins that take damage in water — the Enderian and the Blazeborn. It goes on any enchantable armour piece, up to level IV, and it is mutually exclusive with Protection, Blast Protection, Fire Protection and Projectile Protection.

Enchantment id: origins:water_protection

Slots	armour (helmet, chestplate, leggings, boots)
Max level	4 per piece, and the four pieces are added together
Weight	2 — as rare as Blast Protection
Obtainable from	the enchanting table, villager trades, enchanted books in loot
Exclusive with	#minecraft:exclusive_set/armor (the vanilla Protections)

What it does#

It buys you time, not hit points. Each combined level adds 6 ticks — 0.3 seconds — to the gap between hits, up to 8 levels:

Combined level	Gap between hits
0	20 ticks (1s)
2	32 ticks (1.6s)
4	44 ticks (2.2s)
6	56 ticks (2.8s)
8 or more	68 ticks (3.4s)

Each hit is still a flat 2 damage. origins:hurt_by_water is in #minecraft:bypasses_armor, #minecraft:bypasses_shield and #minecraft:bypasses_enchantments, so nothing — armour points, Protection, a shield, or Water Protection itself — reduces the number. Armour only ever changes how often it lands.

There is no enchantment level that makes you immune. Conduit Power does: while minecraft:conduit_power is active, water and rain stop hurting entirely.

Where the numbers live#

All of it is one origins:water_vulnerability power, and every number in it is yours to change:

{
  "type": "origins:action_over_time",
  "interval": "20 + min(enchantment[origins:water_protection, armor, sum], 8) * 6",
  "entity_action": {
    "type": "origins:damage",
    "amount": 2,
    "damage_type": "origins:hurt_by_water"
  },
  "condition": {
    "type": "origins:and",
    "conditions": [
      {
        "type": "origins:or",
        "conditions": [
          {
            "type": "origins:fluid_height",
            "fluid": "minecraft:water",
            "comparison": ">",
            "compare_to": 0.0
          },
          { "type": "origins:in_rain" }
        ]
      },
      {
        "type": "origins:status_effect",
        "effect": "minecraft:conduit_power",
        "inverted": true
      }
    ]
  }
}

interval is an Expression: 20 is the bare gap, 6 is what a level is worth, 8 is where it stops mattering. Because the interval is an expression, the power tests its condition every tick — so the first hit lands the moment you step into the rain, and putting armour on lengthens the gap before the next one.

Swap the origins:status_effect condition for something else to move immunity somewhere else, or delete it to take immunity away.

The enchantment itself has no effects of its own. It is a marker that the power reads, which is what makes the whole mechanic live in one file.
