Inner Sight

Illuminates nearby enemies making them easier to hit for you and your party.

Inner Sight is the first skill of the Amazon's Passive and Magic tree (level 1, no prerequisite; it unlocks Slow Missiles). It is a cast that puts a state on every enemy within its radius, cutting their defense by a flat amount for a time. The numbers that decide it are the cut, −815 at level 20, and the duration, 8 seconds plus 4 a level.

The numbers

• Defense comes from the row's damage columns, applied as aurastatcalc1 = -edmn to the target's armor class: EMin 40 at level 1, then +25 a level to level 8, +45 to 16, +60 to 22, +80 to 28 and +100 past that (EMinLev1–5). That is −815 at level 20 and −1,615 at level 30. The Basin's page gives the same five brackets.
• Duration is ln34 ÷ 25: Param3 200 frames plus Param4 100 a level, so 8 seconds at level 1 and 84 at level 20.
• Radius is ln56: Param5 27 with Param6 0 a level, printed as × 2 ÷ 3 = 18 yards at every level, so the column is left out. The Basin's page records 13 1/3 yards for the 1.10–1.13 game and 18 for the current one.
• Mana is a flat 5 (mana 10 in halves, manashift 7, lvlmana 0).

Every line reads lvl: +skills from items deepen the cut and lengthen the duration.

How it works

Inner Sight is cast at Casting Speed speed and applies a state (auratargetstate innersight) to each enemy in the radius; the state carries the defense cut and lights the target up. The Basin's page notes that the glow shows through darkness and closed doors, so the skill also scouts.

The cut is a flat subtraction from the monster's defense, which is the denominator of the Chance to Hit formula; see Defense Rating for how monsters' defense is built. The Basin's page places it: after the Stone Skin modifier has doubled a unique monster's defense, and before any +% defense, and it cannot take defense below zero. It is not the same stat as Target Defense Reduction on items, and the two are applied separately.

The Basin's page warns that the character screen's chance to hit does not include the cut: the real chance against an affected monster is higher than the screen shows.

Recasting follows the usual rule for states: by the Basin's page, a cast of equal or higher level replaces the duration and the cut, a lower level does not overwrite a higher one. It does not conflict with Slow Missiles or with curses; all three can sit on one target.

Synergies and +skills

No synergies: the row has no SymPerCalc column and the skilldesc row has no dsc3 line, and no skill reads Inner Sight's points. The Basin's page notes the Rogue Scout mercenary casts it as well.

Against players

Inner Sight deals no damage, so the player-versus-player damage rule has nothing to cut, see Player versus Player. The Basin's page says nothing about its effect on hostile players.

Build notes

• Level 20: −815 defense in 18 yards for 84 seconds, 5 mana.
• The cut is flat, so it matters most against monsters whose defense is in the hundreds, and least against those in the thousands; +skills lift it 100 a level past 28.
• One hard point gives a −40 cut and an 8-second scouting light; the duration from +skills alone makes that point usable all game.
