Titanium Add-on v6.3.13 — The Intelligent Update

✨ New

• Titans Lab dungeon is back, fully rebuilt using the modern Jigsaw Structure System. Generates underground in cave biomes (spacing 13 / separation 6, height range 30–110 above bottom). This replaces the old hand-placed structure + feature/feature_rule system used pre-GO!.
• All-new Payback system (v4 — Adaptive Payback). Misusing Titanium+ tools and armor now triggers LOW/HIGH tier debuffs dynamically based on damage taken/dealt and whether the item is enchanted, instead of the old fixed effect per tool. Includes a 1-second per-player cooldown so it can't spam-trigger.
• New Advancement system. Titanium+ gear buffs (Strength, Haste, etc.) are now fully script-controlled, replacing the old tick.json + per-item .mcfunction setup. Payback now temporarily suspends the Advancement buff of the triggering item and restores it after 1 second.
• Titanium Coating can now be crafted at a vanilla Crafting Table, in addition to the Titanium Workbench.

🔧 Changed / Reverted

• The Titan no longer spawns naturally. The temporary natural-spawn behavior added in GO! Edition (light level 0–2, 1-in-35 weighted chance) has been removed. The Titan now spawns only inside the Titans Lab structure.
• Roar sound reverted to its original file name/ID (mob.ti_the_titan.roar). No functional or audible change — this is purely an internal identifier fix.

🗑️ Removed

• Old tick-based Advancement effect system: tick.json and all 9 ti_titanium_*_plus_effect.mcfunction files, fully superseded by the new script-based Advancement system.

✅ Carried over from GO! Edition (unchanged in this update)

• The Titan's HP (1000)
• Deepslate Titanium Ore (recipe, block, loot table, smelting)
• 4-attack Normal mode / 2-attack Rage mode pattern

📋 Full changelog if you're updating from v6.1.73 "The Upgrade" (skipping GO! Edition)

If you're coming straight from v6.1.73, here's everything that's changed across both updates combined:

✨ New since v6.1.73

• Titans Lab dungeon rebuilt using the modern Jigsaw Structure System (replaces the old hand-placed structure)
• Deepslate Titanium Ore (block, recipe, loot table, smelting)
• Adaptive Payback system (v4) — LOW/HIGH tier debuffs based on damage/enchantment instead of fixed effects
• Script-controlled Advancement system for Titanium+ gear buffs
• Titanium Coating now craftable at a vanilla Crafting Table (previously Workbench-only)
• The Titan now has 4 attack types in Normal mode and 2 in Rage mode (was a simpler pattern)
• The Titan's HP raised from 950 → 1000

🔧 Changed since v6.1.73

• The Titan's dungeon spawn is now handled by the Jigsaw structure system itself. The old proximity-trigger script (spawning via an ti_ruins_center armor stand within 18 blocks) has been removed.

🗑️ Removed since v6.1.73

• Custom weapon-hit sound system — Titanium tools/weapons no longer play unique attack sounds on hit, and the titanium shield no longer plays a block sound. This existed in v6.1.73 but was dropped and never replaced.
• Old tick-based Advancement effect system (tick.json + 9 per-item .mcfunction files), superseded by the new script-based Advancement system.

➖ Not carried over from v6.1.73

• The Titan briefly gained a natural-spawn chance in GO! Edition; that was removed again in this update. Natural spawning was never part of v6.1.73 either, so behavior here is effectively back to where it started.

Requires @minecraft/server 2.8.0 / @minecraft/server-ui 2.1.0, min engine version 1.21.131.
