Description

10 / 40

Moves behind a target within 20m and deals 610 (+100% Attack) damage, rotates, and inflicts Stun for 3s. 10 Stagger Gauge Damage

Damage and healing read like the game's tooltip before it adds your stats: the flat amount from the skill tables and the share of your Attack on top (“51 (+43% Attack)”).

Damage by level

Flat amounts and the share of Attack from SkillEffect (EffectValueList) and its level table. The game's tooltip adds your Attack to the flat part, so the damage you see in game depends on your gear. Levels above 10 are greyed: points do not buy them.

PvP set: the same table row carries a second set of numbers, lower for most skills. The files do not name it; patch notes tune a skill's PvE and PvP damage separately, so we read it as the values used against players.

What a point buys

Our calculation from the skill tables: the flat part a level adds, divided by the points that level costs (SkillAcquireData).

From level 1 to 10, Shadowstrike's flat damage goes from 52 to 610 per use (+558) for 21 skill points: 26.6 damage per point. The share of Attack stays at 100% at every level, so levels add only the flat part.

One more level past 10 (a Daevanion node or a gear effect) adds 74 flat damage per use.

Formula: (flat at level 10 − flat at level 1) ÷ points for levels 2–10. A min–max range counts at its midpoint; critical hits, defense and damage boosts are left out.

Raising Shadowstrike above level 10

Points buy levels 1–10. Daevanion skill nodes and the skill effects soul binding adds to gear raise it further, up to level 40.

From DaevanionNode: skill nodes add levels to one skill. The path cost counts every node on the cheapest way there from the board's start (our calculation, as in the planner).

Gear: soul-binding skill effects

Guard, Greatsword, Longsword, Dagger, Bow, Spellbook… (1,313 items): soul binding draws up to 3 skill effects, each landing with 20%; a landed effect picks Shadowstrike 833 times in 10,000 and adds +1 level.

Chance one item gets it: 4.92% — 1 − (1 − 20% × 8.33%)3, our calculation, assuming the draws are independent.
