Diablo 2 Assassin Skills and Synergies
Explore all 30 Diablo 2 Resurrected Assassin skills, prerequisites, synergies and rank values. Plan your build with the free D2R skill calculator.
Open the free D2R Skill Calculator & Build Planner and choose Assassin from the class tabs.
Diablo II skill calculator and build-planning reference
Plan skill allocations for all eight classes, including the Reign of the Warlock class. Each tree uses the released game's page, row and column positions. The planner distinguishes invested points from bonus skill levels, enforces prerequisites and level limits, and stores named builds on this device within the selected profile.
Skill points, bonuses and saved builds
Characters earn one skill point per level after level 1. Den of Evil, Radament and Izual together award four additional skill points per difficulty, for up to twelve quest points and a maximum of 110 points at level 99. Select the rewards actually earned rather than assuming every quest is complete. A skill's unlock level also limits how quickly further points can be invested.
The current allocation uses your selected level. Target allocations use a level-99 point budget with the selected quest points. Bonus skill levels do not spend earned points and do not fulfill prerequisites. Some mechanics specifically use invested points rather than effective skill levels. Each build retains its edition and patch; changing a patch does not silently discard its allocation.
Create, rename or duplicate builds, add notes and leveling checkpoints, and export a backup before clearing browser data. Local saves do not synchronize between devices. Build sharing excludes private notes. The calculator is a planning reference, not a full gear, enemy-resistance or combat simulation.
Each saved build belongs to one class. You can keep multiple builds for the same class. The saved-build dropdown switches plans, while class tabs resume a matching plan or open a temporary experiment without requiring a save or changing existing builds. On phones and installed web apps, open this reference from the app menu rather than a floating shortcut over the trees.
Equipment, +skills and synergy accounting
Open +Skills beside level and quests to enter manual all/class, tree, elemental-type or individual skill bonuses. Open Gear to search compatible unique, set and runeword items by name, set variable skill rolls, or enter a generic bonus for an undecided slot. Manual bonuses and equipment add together; do not enter the same item twice in both places. The complete equipment and charm configuration is saved, backed up and shared with the build. A selected item's version remains pinned rather than silently changing its rolls when you compare build patches.
Annihilus adds one to all skills. Hellfire Torch adds three to its particular class; this skill bonus is fixed, and a different-class Torch adds no class skill levels. Skill grand charms add to the selected tree. Classic cannot use these charms. Distinct set pieces activate their eligible piece, partial and full-set bonuses; wearing the same set ring twice does not manufacture a missing piece. A completed set receives a decorative glow, not an additional calculated bonus.
Invested points, manual bonuses and equipment contributions are displayed separately. An effective rank above twenty is blue; an icon with the maximum invested points has a green border. General +skills do not learn a skill or fulfill its prerequisites. A direct individual skill grant can make a skill usable without investing, but never creates invested synergy points.
Most damage synergies use invested points only. Read each skill's reference breakdown: effective-level passives and masteries are explicitly distinguished, including Skeleton Mastery references. Supported Sorceress damage components include applicable Fire or Lightning Mastery and verified equipment percentage-skill-damage modifiers. These percentage modifiers are additive with mastery and multiply the synergized component. Cold Mastery instead reduces enemy resistance; it does not multiply displayed raw cold damage.
This is not a complete combat simulator. Enemy resistance, immunities, PvP penalties, weapon damage, summons, triggered spells, item auras and some missile/hit-frequency calculations require additional models. Unsupported tooltip values are marked not calculated, not filled with guessed numbers. Random item properties must be entered explicitly and are not all granted at once.
Choose a class or skill tree using its named tab. Click or tap a skill square to invest one point; hold its icon to maximize invested points. Right-click or use minus to remove one point, or hold minus to remove eligible invested points without breaking prerequisites. Click the rank, or hold it, to enter an exact invested-point count. Hover with a mouse or use the plus control for skill details. Scrolling cancels a pending hold. Bonuses are separate from invested points.
Green synergy lines flow from contributing skills into the active skill. In single-tree phone view, the S toggle pins incoming synergies even when using a PC mouse. Cross-tree sources appear as green ghost skills at their own level rows; click or tap a ghost to open its source tree without spending points. The destination stays green until you hover over or interact with it.
Choosing a D2R skill calculator
Looking for the best D2R skill calculator for your build? Compare class and patch coverage, prerequisite checks, hard-point synergy accounting and gear bonus handling. This free skill calc supports Amazon, Assassin, Barbarian, Druid, Necromancer, Paladin, Sorceress and Warlock, on PC and phone. It is a build-planning tool, not a ranked build guide or a guarantee of the strongest setup.
Browse all Diablo 2 skill trees and class references. Use runeword recipes, unique equipment, set bonuses, Horadric Cube crafting and Terror Zone farming references alongside your build.
The seven original classes use skill art from Blizzard's official Arreat Summit archive. Warlock icons are cropped from user-supplied in-game skill-tree screenshots, not downloaded from that archive or another gaming site.
Released patch comparison
Available snapshots: 3.2.92777 and 3.3.93847. Compare the same invested points and bonuses across these snapshots. Green means a verified beneficial change, red means a verified disadvantage, and neutral labels describe mixed or context-dependent changes. Lower mana cost can be beneficial even though its arrow points down. Unchanged skills are not presented as buffs or nerfs. PTR proposals and reverted changes are excluded.
The values below show isolated skill ranks 1 and 20, without synergy investment, bonus levels, equipment or mastery bonuses. The interactive calculator incorporates your saved bonuses and supported synergy/mastery contributions. Damage refers only to the calculated skill component. Outputs needing monster, weapon, missile or special game context are explicitly marked rather than guessed. They are not promises of in-game damage.

Verification and limitations
Skill identities, coordinates, unlock requirements and native formulas come from pinned released extracts. Native calculation data does not completely describe every runtime behavior. Special-context outputs are not calculated until their interpretation is verified. The historical comparison currently covers two released snapshots, not every past patch or PTR.
