Class Trees

Hero level 2 awards the first Class point, and every later hero level awards one more. Buying a root permanently selects that class until a full paid respec; unspent points may be banked after the selected tree is filled.

Calculation order: Existing attributes and Heart affixes resolve first, static Class Tree modifiers apply second, and cast-conditional bonuses apply last.
Successful casts: Alternating Current, Guarded Rhythm, Banked Thunder, and Measured Ruin advance or consume only when a cast completes successfully. Interrupted casts spend no mana and start no cooldown.
No hybrid path: Pulseweaver and Siegewright have separate versions of their shared attribute and field-craft nodes. There are no cross-links or blended allocations.

Aura Hearts

Aura Hearts cannot be cast. Most equipped Auras pulse once every 1 second; Crooked Horizon pulses every 2.3 seconds. Each pulse selects exactly one hostile monster inside its 220-pixel base radius, and its debuff lingers for 2.1 seconds by default.

Aura Skill Heart rules
Heart	One-target pulse	Base potency
Rust Halo	Shreds the defense family matching the Heart's affinity	12% Armor or Magic Defense Shred
Rimebound Circle	Slows movement	18% movement slow
Storm Debt	Adds one temporary vulnerability stack	+2% damage taken per stack; 5 stacks
Crooked Horizon	Every 2.3s, blinds and slows attack and special recovery	20% recovery slow
Dread Lantern	Reduces damage dealt by the selected monster	15% damage reduction
Hex of Many Wounds	Marks the monster for each different active condition	+4% damage taken per condition; 3 conditions

Targeting: Each pulse affects one monster. Unaffected in-range monsters are prioritized, then the Aura refreshes the monster whose copy is closest to expiring.
Aura modifiers: Aura Radius, Debuff Potency, Lingering Duration, and Pulse Frequency modify their matching values. Aura Hearts can also roll the shared Passive Potency and Attunement Speed factors.
Potency: Passive Potency and Debuff Potency multiply together. Identical Aura effects use the strongest active value instead of adding together.
Attunement: Attunement Speed shortens the delay before the first pulse after the Aura is equipped or reset. Pulse Frequency controls all later pulses.

Passive Hearts

Passive Hearts consume a normal loadout slot, cannot be cast, and continue updating automatically while equipped. When compatible, Passive Potency multiplies the listed benefit; Attunement Speed shortens the time needed to build or ready it.

Passive Skill Heart rules
Heart	Build condition	Full effect	Reset or decay
Stillwater	Avoid starting an active Heart cast for 10s	+3 mana regeneration per second	Starting an active Heart cast resets it
Stonebound	Stand still for 5s	+16 armor and magic resistance	Movement decays buildup twice as fast
Windborne	Move continuously for 4s	+18% movement speed and +9% evasion	Damage or 0.2s standing still resets it
Calm Current	Avoid being hit for 6s	The next spell cast does not stop movement while casting	Starting that spell consumes the ready effect; being hit resets buildup

Power, damage, and defense

Base active-Heart power: 12 + item level × 2.4 + effective Power × 2.6. The active archetype's damage multiplier and Heart damage modifier apply afterward. Passive and Aura Hearts deal no damage and do not use this formula.
Eligible equipment stats: Equipped attributes, critical chance and damage, armor or magic piercing, Bloodbound, Aetherbound, stun, and compatible general combat stats apply. Weapon-only damage and attack-speed modifiers do not raise Heart damage.
Earth and Force: Both use armor, armor piercing, Armor Shred, and armor-matching Defense Penetration. Earth can inflict Bleed; Force can inflict Blind.
Elemental: Fire, Ice, and Lightning use magic defense, magic piercing, and Magic Shred while keeping separate combat-log identities and palettes.
Damage-type animations: Every archetype keeps its readable base shape, then adds a damage-specific animated motif: Earth impact shards, Fire embers, Ice crystals, Lightning forks, or orbiting Force rings.
Heart critical modifiers: Critical Chance and Critical Damage affect only hits from that Heart and add to the hero's equipped critical stats. Total critical chance remains capped at 75%.
Matching defense penetration: Defense Penetration reduces armor for an Earth or Force Heart and magic defense for a Fire, Ice, or Lightning Heart. It affects only that Heart.
Target-health damage: Healthy-Target Damage applies at or above 80% target health. Injured-Target Damage applies at or below 30% target health.
Bloodbound and Aetherbound: A damaging Heart combines the Bound roll on that Heart with eligible equipped gear. Positive Bloodbound restores life linearly over 3 seconds, while positive Aetherbound restores mana over 1.5 seconds; a new hit replaces the current effect. Incoming damage interrupts positive Bloodbound, while spending mana interrupts positive Aetherbound. Harmful T1–T3 rolls drain the resource at the matching rate and cannot be interrupted; Bloodbound stops at 1 HP.
Armor and Magic Shred: A surviving target is Shredded for 4 seconds after the hit. Armor Shred rolls on Earth and Force Hearts; Magic Shred rolls on Fire, Ice, and Lightning Hearts. The applying hit is unaffected, but subsequent matching-defense hits from any source benefit.
Casting: Active Heart windups hold the hero in place until the cast completes, except when Calm Current readies movement for the next spell. Every archetype's base windup is 60% shorter. Each effective Quickness rank above 1 adds 2% cast speed, combining additively with the Heart's Cast Speed modifier. The separate signed Cast Time modifier may shorten or lengthen the windup. Dodging interrupts the cast unless Slipcast suspends it until the dodge ends.
Signed Cast Time: A negative Cast Time roll shortens the windup; a positive roll lengthens it. The modifier never rolls zero and can coexist with Cast Speed.
Caps: Cooldown reduction and mana-cost reduction cap at 50%. Final cast time cannot fall below 0.1 seconds.

Affix tiers and Heart strength

Skill Heart tiers are not unlocked by item level. Instead, every finished Heart must fit a signed total-strength range determined primarily by item level, with a smaller rarity bonus to the upper bound.

Shared Skill Heart tier-strength curve
Tier	T1	T2	T3	T4	T5	T6	T7	T8	T9	T10
Base strength	-7	-5	-3	+1	+2	+3	+4	+5	+6	+7

Affix strength: The tier's base strength multiplied by that modifier's catalog weight. The Heart's strength is the sum of all modifier strengths; the exact value rolled within a tier does not change the rating.
Allowed range: Minimum = −7 + item level ÷ 10. Maximum = 7 + item level ÷ 10 + rarity rank ÷ 2. A level-0 Ok Heart allows −7 through 7; a level-99 DopeAF Heart allows 2.9 through 19.4.
Factor drawbacks: Every modifier in the Factor table can roll at any tier. T1–T3 are harmful; T4–T10 are beneficial.
Bad value bands: Ordinary factors roll −90%…−70% at T1, −60%…−40% at T2, and −30%…−15% at T3. Cast Time reverses those signs because a longer windup is harmful. Critical Chance and Critical Damage use smaller custom drawback bands; Bloodbound and Aetherbound use −3%…−2%, −2.2%…−1%, and −1.5%…−0.5% at T1–T3.
Area of Effect: Widens Wave's cone, lengthens Wall, expands the radii of Nova, Field, Eruption, Meteor, Storm, Orbit, and Mine, and always keeps collision aligned with the visible footprint.
Effect Duration: Extends persistent Field, Wall, Storm, Orbit, Turret, Mine, and Summon Hearts without changing their tick or attack cadence.
Deployment-specific factors: Turret can roll Attack Speed and Targeting Range; Mine can roll Trigger Radius and Arming Speed; Summon can roll Summon Health, Movement Speed, and Attack Speed. These seven factors cannot roll on other archetypes.
Passive factors: Stillwater, Stonebound, and Windborne roll Passive Potency and Attunement Speed. Calm Current rolls only Attunement Speed because its movement effect is binary. Both factors use the same harmful T1–T3 and beneficial T4–T10 curve.
Aura factors: Every Aura rolls from Aura Radius, Debuff Potency, Lingering Duration, Pulse Frequency, Passive Potency, and Attunement Speed. All six use harmful T1–T3 and beneficial T4–T10 values.
Behavior modifiers: Active Hearts can roll Multicast, Pierce, Chain, Echo, Homing, Knockback, Vacuum, Returning, Relay, ailments, and Root. These are beneficial-only and start at T4. Multicast specifically rolls at T4, T7, T10 for +1, +2, and +3 instances. Swarm, Turret, and Summon use 50% of rolled ailment and Root proc chance.
Multicast damage: Mine and Summon gain 30% total damage per added instance while dividing that budget evenly across every copy. Added Orbit motes deal 75% damage, added Spiral blades deal 60% damage, and Turret Multicast shots require distinct targets.
Vacuum: After damage and normal Knockback resolve, each surviving target is pulled toward the skill's focal point. Nova and Wave pull toward their origin; aimed and placed archetypes pull toward their target point.
Returning: Bolt-only. After the outbound Bolt hits or reaches maximum range, it flies back toward the hero and deals the listed percentage of its original damage along the return path.
Relay: The first struck target launches one reduced-damage copy toward the nearest unhit target in range. The relayed copy preserves the Heart's archetype shape, making it distinct from a single-target Chain bounce.
