Twister

Release several small whirlwinds that cut a path through your enemies.

Twister is the Druid's level 18 Elemental skill, requiring Cyclone Armor; it unlocks Tornado. It is a cast that releases three small whirlwinds that wander towards the targeted point, each dealing physical damage and a short stun to what it touches. The damage is modest, 104–106 at level 20 per hit; the stun is a flat 0.4 seconds that only Arctic Blast's hard points lengthen; and the skill's larger role is as a synergy for the two wind skills above it.

The numbers

• Damage is the MinDam/MaxDam columns: 12–16 at level 1 in the table, then +7 a level on both ends to level 8, +11 to 16, +15 to 22, +18 to 28 and +21 past that (MinLevDam1–5 and MaxLevDam1–5). The row's HitShift is 7, so the tooltip prints half of the column: 6–8 at level 1, 41–43 at level 10, 104–106 at level 20, 194–196 at level 30. The Basin's formulas give the same, 2 × slvl + 4 at the low levels.
• Stun length is calc2 = Param2 + Param7 × Arctic Blast hard points frames, ÷ 25: Param2 10 frames is 0.4 seconds at every level, so the line is not in the table; each hard point in Arctic Blast adds Param7 2 frames, 0.08 seconds, which the tooltip states as +20% duration a level (par7 × 100 ÷ par2).
• Missiles are calc1 = Param1 = 3.
• Mana is a flat 7.

The damage line reads lvl, so +skills from items raise it; both synergy lines read hard points only.

How it works

Twister is a cast on your cast rate (Casting Speed) and cannot be used as a werewolf or werebear. The Basin's description: three twister missiles that apply physical damage and the stun on collision, following random paths in the general direction of the point targeted, and the same paths each time if you keep casting at the same point. Each twister lasts 50 frames (2 seconds) and carries a next delay of 25 frames, so it can damage and stun a target more than once but not more often than every 26 frames: at most twice per twister on a target that stays in its path. The damage goes through Dealing Physical Damage and can be blocked (Blocking); the stun is a stun length on the target, see Hit Recovery and Stun.

The Basin says faster cast rate does not raise Twister's damage rate or the time a target spends stunned; it only packs the twisters closer together, which raises the chance one is in range when the next delay expires.

Synergies and +skills

Two damage synergies at +10% damage per level (Param8 = 10, "Damage synergy"): Tornado and Hurricane, through DmgSymPerCalc = (skill('Tornado'.blvl) + skill('Hurricane'.blvl)) × par8. One duration synergy: Arctic Blast, +20% stun duration per level (Param7 = 2 frames on a 10-frame base, the table's "Duration Synergy"). All three read hard points only. Twister's own hard points are a synergy for Cyclone Armor (+7% absorbed a point), Tornado (+9% damage a point) and Hurricane; those pages give their lines.

Against players

A player's hit on another player is cut to 17% of its value (difficultylevels.txt PlayerDamagePercentVSPlayer) before anything else, see Player versus Player. The Basin's page says nothing more about Twister against players.

Build notes

• The stun is 0.4 seconds flat and grows only by 0.08 seconds per hard point in Arctic Blast: 20 points there make it 2 seconds, and no +skill touches it.
• One hard point and +skills is the common investment: the damage is small, 104–106 at level 20 even before the once-per-26-frames ceiling, and the hard points are worth more as +9% and +7% to Tornado and Cyclone Armor.
• Seven mana for three missiles, flat at every level.
