Sorcerer Tower Defense Traits & Binding Vows Guide

Traits—also called Binding Vows—are the permanent modifiers you attach to units in Sorcerer Tower Defense. A Cursed Scroll applies a unit’s first vow. After that, Cursed Crystals reroll the vow until you land something worth keeping. This guide covers all 18 normal traits with community-checked approximate odds, rarity-based crystal costs, Update 32.0 Anniversary Cauldron notes, and which traits belong on Strongest Sorcerer versus farm units.

Pair this page with Piñata Rush for event crystal income, Codes for free Anniversary Crystals, the Tier List for which units deserve expensive rolls, Update 32.0 for Cauldron timing, Evolves & Ascended Grade for material desks, and How to Get Strongest Sorcerer when you are deciding whether to trait a base unit or wait for an awaken.

How Binding Vows work

1. Obtain a Cursed Scroll (Casino shop, Gauntlet shop, battle pass tracks, and the High Stakes tutorial often hand a free first scroll).
2. Use the scroll on a unit that has no trait yet. That applies the first Binding Vow from the normal pool.
3. Spend Cursed Crystals to reroll. Each reroll replaces the current trait; there is no multi-slot stack of normal traits.
4. Stop when the trait matches the unit’s role. Do not “just one more roll” on a Mythic farm if you still need crystals for a Special Grade carry.

Community data-mined tables treat each trait as a weight against a 10,000 total, so the percentages below are weight ÷ 10,000. Odds are approximate and can shift if the live build rebalances weights—recheck after major patches.

All 18 normal traits (approximate odds)

Trait	Approx. chance	Effect (community / data tables)
Power I	11%	+5% damage, +2% cooldown
Haste I	11%	−5% cooldown, −1% damage
Scope I	11%	+7.5% range, +1% cooldown
Power II	10%	+10% damage, +2% cooldown
Haste II	10%	−10% cooldown, −1% damage
Scope II	10%	+10% range, +1% cooldown
Power III	8.5%	+20% damage, +2% cooldown
Haste III	8.5%	−15% cooldown, −1% damage
Scope III	8.5%	+15% range, +1% cooldown
Summoner	3.25%	+25% summon HP
Fortune	3.25%	+20% money gain, +5% upgrade cost
Caster I	1.1%	−20% ability cooldown, −5% attack damage
Might	1%	+75% damage, +25% attack cooldown
Rapid	1%	−33% cooldown, −15% range
Efficiency	1%	−20% upgrade costs, +10% placement cost
Caster II	0.6%	−30% ability cooldown, −10% attack damage
Heavenly Restriction	0.2%	+200% damage, but cannot use abilities
The Honored One	0.1%	+125% damage, −15% ability cooldown, −20% cooldown, +20% range, placement limit 1

The Honored One is the rarest normal trait at about 1 in 1,000 rolls. Heavenly Restriction sits next at about 1 in 500. Everything else is filler, role niche, or a stop-gap until you can afford another crystal dump.

Cursed Crystal reroll costs by rarity

Crystal cost scales with the tower’s rarity tier. Spending three crystals per Special Grade roll adds up fast—budget before you open the menu.

Rarity	Crystals per reroll
Common	1
Uncommon	1
Rare	1
Epic	2
Legendary	2
Mythic	2
Special Grade	3
Anniversary	3
Ascended Grade	3

Trait shops commonly list Cursed Crystals and Cursed Scrolls for Casino / related currencies (community tables often cite crystal purchases around 150 and scrolls around 10,000 in the Casino-facing shop). Prefer free scrolls from tutorials and battle pass before buying. Anniversary Update 32.0 also injects Anniversary Crystals for a separate Cauldron pool—do not confuse those with normal Cursed Crystal rerolls.

Trait priorities by role

Carries that lean on abilities (Strongest Sorcerer and friends)

Strongest Sorcerer (Awakened) and similar ability-heavy Special Grades lose a huge share of their kit under Heavenly Restriction, because Restriction disables abilities while tripling (roughly) basic attack damage. On those units, chase:

1. The Honored One — best all-around package if you accept the placement limit of 1.
2. Caster II / Caster I — ability cooldown cuts keep domains and ultimates cycling.
3. Power III or Haste III — acceptable parking traits while you farm more crystals.

Avoid parking Heavenly Restriction on ability carries just because the percentage looks big. Read How to Get Strongest Sorcerer before you burn a scroll on a base Strongest you plan to awaken—trait planning often follows the awakened form you will actually place.

Pure attack / farm-style units

Units that live on auto-attacks or money generation love different vows:

• Heavenly Restriction — excellent when abilities are weak, unused, or mostly cosmetic. Community value lists routinely price Restriction copies of farms and simple DPS towers above untraited versions.
• Fortune — default chase on Tree of Life, Slot Machine, Wealth Sorcerer, and other cash engines. The upgrade-cost penalty is real; still worth it on dedicated farms.
• Efficiency — helps expensive upgrade trees when you are not already Fortune-locked.
• Summoner — only meaningful on kits that actually spawn summons with HP that matters.

Hit-count boards (Stage Piñatas)

During Piñata Rush and end-of-stage piñatas, every hit deals 1 damage. Cooldown and multi-hit traits matter more than raw damage multipliers. Rapid, Haste III, and buffers that raise attack speed (Dance Floor synergy) outrank Might’s slow heavy hits. Plan a second board for candy phases instead of forcing your Hollow Purple nuke trait onto a piñata timer.

Anniversary Cauldron traits (Update 32.0)

The lobby Cauldron rolls a dedicated Anniversary trait set with Anniversary Crystals. High-end celebration outcomes include styles such as Prize Wheel and The Anniversary. Critical rules from the patch notes:

• Traits stay on the unit forever after you apply them.
• Rerolls end when the Update 32.0 event ends (official window roughly November 14–21, 2026 UTC—confirm the in-game calendar).

Spend Anniversary Crystals on units you will still play after the party leaves the lobby. Do not dump the entire crystal bank on a meme placement you will shelf in December. Normal Binding Vow odds above remain the permanent baseline outside the event pool. Full patch context lives on Update 32.0.

Redeem celebration codes early so crystals arrive while the Cauldron is live—start from Codes (SpinTheWheel and related strings when active).

Practical reroll plan

1. Scroll only keepers. Never open a Binding Vow on a unit you are about to scrap or trade as raw fodder.
2. One crystal sink at a time. Finish the Special Grade carry before spraying crystals across five Mythics.
3. Know your stop traits. Caster II on an ability carry, Fortune on a farm, Restriction on a pure auto-attacker—stop and play.
4. Respect placement limits. The Honored One’s single-copy rule can break multi-place strategies; check the Tier List notes for that unit.
5. Separate event and normal budgets. Anniversary Crystals ≠ Cursed Crystals. Use each currency in its own UI.

Common mistakes

• Rolling Heavenly Restriction onto Strongest Sorcerer (Awakened) and wondering why the domain stopped carrying.
• Buying Casino scrolls before claiming the free High Stakes tutorial scroll.
• Treating I / II tier Power-Haste-Scope rolls as “done” on endgame units.
• Ignoring Fortune on farms while chasing Honored One on a cash tree that never uses the damage package.
• Waiting until the last Anniversary day to learn the Cauldron UI.

Traits are a long-term account investment. Scroll carefully, reroll with a role in mind, and let Update 32.0 Cauldron rolls land on units that survive the celebration.
