Inscription of the Shockwave

Splash = the damage the basic attack dealt x 30 x 0.01, dealt to every hostile in the square of half width 1 around the target. The target's own tile is skipped, which leaves up to 8 neighbours.

Where it lands: Each splash is its own execution with a fixed value, so it re-enters the damage pipeline from scratch: it rolls its own critical and guard and is mitigated by the victim's physical resistance.

When it runs: After the basic attack has landed and its damage is known.

What it applies to: Basic attacks only. It fires on normal, critical and guarded hits alike: the gate is that the hit was applied, which excludes only misses and immune results.

Worked numbers

Splash before each victim's own resistance and critical roll.

Rule of thumb: Every 100 damage on the main target is 30 damage to each neighbour.

Things the tooltip does not tell you

• The splash is always physical, whatever the damage type of the basic attack that triggered it.
• The primary target is explicitly skipped, so it is never hit twice.
• The area is a square of half width 1 around the target, read from the inscription's first value. It is not a ring of exactly 8: fewer neighbours means fewer hits.

How it interacts with other effects

• Sinking compounds into it. Sinking's bonus is already inside the damage the basic attack dealt, so the splash carries it: a 72 point Sinking proc turns a 67.5 splash into 116.1, exactly 1.72 times.
• A permanent damage dealt bonus double dips here, once in the base hit and again on each splash's own bracket. Sinking only single dips, because its bonus is scoped to the one execution that produced the base hit.
• Splash hits cannot re-trigger Shockwave, Storm or Sinking. What publishes them is the inscription, not a skill, and all three of those gate on a basic-attack skill.
