Tower Defense

Strategic tower defense with A* pathfinding, elemental damage types, and upgrade trees

Materia System

Towers are built from a base chassis and customized with runes. Place a base on the grid, then socket runes to define its behavior.

Base Types

Base	Cost	HP	Slots	Shape	Fire Rate	Range
Light	40g	150	3	Triangle	Fast (0.7x)	Standard
Medium	90g	300	4	Square	Normal (1.0x)	Standard
Heavy	160g	500	5	Pentagon	Slow (1.3x)	+1 cell

Rune Categories

Artillery (3): Define the firing mode — projectile, beam, or area. No damage on its own.
Energy (5): Provide base damage + elemental effects — physical, ice, fire, poison, electricity
Mod (11): Stat modifiers — speed, range, crit, splash, pierce, chain, etc.
Special (2): Unique abilities — self-heal or burst fire override
Cosmetic (8): Visual-only effects

Rune Tiers

Tier	Name	Rarity
T1	Brut	Common (shop)
T2	Distillé	Uncommon (shop)
T3	Purifié	Rare (shop)
T4	Concentré	Epic (shop, rare)
T5	Absolu	Legendary (fusion only)

How Towers Work

Artillery runes define how the tower fires (projectile, beam, or area) — each creates an independent weapon with its own cooldown. Energy runes define how much damage the tower deals and add elemental effects to all weapons. A tower without energy runes fires blanks (0 damage). Multiple energy runes stack their damage. Mods stack additively or multiplicatively to enhance stats.

Runes can be unsocketed by clicking them in the tower info panel — they return to your inventory for free. The Thief enemy can also steal runes.

Mechanics

Tower HP: Towers have hit points. Soldiers, bosses, and enemy turrets attack nearby towers.
Repair (R): Damaged towers can be repaired for gold (proportional to damage).
Destroyed towers are removed from the map and must be rebuilt.
Rune socketing: Runes are permanent once placed. Choose wisely.
Thief enemies: Steal runes from your towers — kill them to recover.
Cursed enemies: Permanently curse runes, inverting their effects.
Kamikaze enemies: Runners and bombers follow their path until they detect a tower in range, then charge straight at it and explode on contact.
Pollution zones: Some kamikaze explosions leave toxic zones that damage towers over time.
Destructible walls: Map walls can be destroyed by towers or bomber explosions, opening new paths.
Enemy tiers: Enemies get stronger as waves progress. Higher tiers are visually larger and more opaque with tier pips below.

Tips

Place towers to create a long winding path — enemies must walk around them
Socket artillery + energy runes — artillery defines the weapon, energy provides the damage
Combine energy runes for multi-element damage (fire + ice = steam)
Stack mod runes for powerful combos (3x Swift = extreme fire rate)
Fuse 3 identical runes to upgrade their tier — T5 Absolu runes are extremely powerful
Use Soin runes on front-line towers to keep them alive
Watch for Thief enemies — they steal runes from your best towers
Protect your most equipped towers from Cursed enemies
Repair damaged towers (R) before they get destroyed — rebuilding is more expensive
Sell and reposition towers as waves change composition
Undo (Z) gives you 3 seconds to reconsider a tower placement
Boss T3+ splits into mini-bosses at low HP — save burst damage for the finish
Wizard T5 drains tower HP — prioritize killing high-tier wizards early

A* Pathfinding

The game uses the A* search algorithm to find optimal paths from spawn points to exits. The grid-based implementation uses:

Manhattan distance as the heuristic function (4-directional movement)
Binary heap priority queue for O(log n) open set operations
Dynamic recalculation when towers are placed or sold

Before allowing tower placement, the system tests whether blocking that cell would cut off all valid paths. This prevents the player from creating impossible situations.

Damage Types & Resistances

Five elemental damage types interact with enemy resistances via multipliers:

Type	Strong Against	Weak Against
Physical	Scouts	Tanks, Bosses
Fire	General	Tanks
Ice	Tanks	—
Energy	Soldiers	Tanks
Poison	Healers	Bosses

Resistance values below 1.0 reduce damage, above 1.0 increase it. Multiple energy runes combine their elemental profiles — a tower with both Fire and Ice runes deals both types.

Tower Targeting

Each tower uses one of five targeting strategies:

First: Enemy furthest along the path (highest threat)
Last: Enemy closest to spawn (lowest threat)
Strongest: Enemy with the most HP remaining
Weakest: Enemy with the least HP remaining
Nearest: Enemy closest to the tower

Materia — Stat Pipeline

Each tower computes its stats from its socketed runes in a deterministic pipeline:

Categorize runes by type (artillery, energy, mod, special, cosmetic)
Weapons: Each artillery rune creates an independent weapon with its own cooldown and stats
Energy: All energy runes merge into a weighted damage profile applied to every weapon
Mods: Additive mods stack linearly (e.g., 3× Range = +2.4 cells). Multiplicative mods compose (e.g., 3× Swift = 0.85³ fire rate)
Specials: Soin adds HP regeneration, Override adds periodic burst fire
Base modifier: Fire rate modifier and range bonus from the chassis type are applied last
Cache: Stats are recalculated only when runes change (socket/remove/curse)

Cursed runes have their effects inverted (bonuses become penalties).

Wave Scaling

Enemy HP scales with wave number: +15% per wave. Gold rewards also scale at +5% per wave. Boss encounters occur every 5 waves with increasingly dangerous escort compositions.

Wave Themes (5-wave cycle)

Wave % 5	Theme	Composition
0	Boss	Boss + tanks + healers
1	Swarm	Scouts + runners + thieves
2	Assault	Soldiers + tanks + bombers + cursed
3	Tank Push	Tanks + healers + runners
4	Mixed	All unlocked enemy types

Scoring

Kill reward: base gold × (1 + wave × 0.05)
Wave bonus: 25 + (wave × 10) gold
Final score: (waves × 100) + total gold earned + (lives × 50)

Important implementation notes:
  - All lib files are ES modules with named exports
  - Canvas 800x800 with DPR scaling
  - Grid: 20x20, cell size = 40px
  - A* pathfinding recalculated when towers placed/removed
  - 3 views (war/shop/craft) toggled by switchView() — unlike grimoire which has 4 views
  - Tower bases: light (40g, 3 rune slots), medium (90g, 4 slots), heavy (160g, 5 slots)
  - Rune system: runes inserted into tower base slots for elemental/damage augmentation
  - Craft: fuse 3 same -> 1 higher tier, craft 2 different -> 1 combined, auto-fuse convenience
  - Inventory: 64 slots max (vs grimoire's 32)
  - Weather system affects gameplay (unique to materia, not in grimoire)
  - Enemy turrets (obstacle.lib.js) can attack towers (unique to materia)
  - Keyboard hotkeys: 1/2/3 for tower base selection, N for next wave
  - Starting gold: 200g, starting lives: 20
  - 6 maps, 6 difficulty modes (same as grimoire)
  - Complex HTML in index.md (craft slots A+B=C not generated by JS)
  - Uses /_lib/panic_v3.js for logging
