Derzki Build & Guide | WoWs Legends

Playstyle

Overview

Derzki is a Tier II Soviet long-range gunboat destroyer reaching 10.2 km: her guns out-reach peer DDs and most cruisers can be kited at the edge of her range. The kit is HE spam from open water rather than cap contesting; the torpedoes are a backup, not the primary threat. Standout traits: best HE fire chance in T2 DDs (7) and best DCP duration in T2 DDs (10 s).

Positioning

Sit in open water at the edge of 10.2 km where peer DDs cannot return fire and most cruisers have to push to engage. The kit is HE pressure from distance, not cap contesting; let your peer DDs take the cap while you kite the rotating cruisers and BBs that come to support it.

Potato Avoidance

Overstaying detection after a torpedo drop

The detection window is a hard timer; if you are still firing guns when concealment closes again, you have already taken more damage than the drop earned.

Signature Traits

Long gun range

10.21 km main battery reach, best of T2 DDs.

High fire chance

7.0% fire chance per HE shell, best of T2 DDs.

Long DCP window

10.0 s Damage Control duration, best of T2 DDs. Stays fire / flood immune longer per activation.

Thick stern plate

14.0 mm stern, best of T2 DDs.

Wide dispersion

84.6 m max horizontal dispersion, worst of T2 DDs. Long-range salvos are noticeably wider than peers'.

Short torp range

4.41 km torpedo range, bottom decile of T2 DDs. Must close to deliver.

Acquisition

How to get Derzki

Derzki is available in the Fiery Destroyers branch of the U.S.S.R. Tech Tree for 13,000 credits after researching it in the branch. Known module upgrades cost up to 2,600 credits.

Builds Beta

Anton Gurin, Rumble, and Sergio Splendento are useful Soviet destroyer commander directions. Inspirations usually start with concealment, then add HP, torpedo reload, gun performance, or speed depending on whether you want safer scouting or harder cap fights.

Magazine HP

The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.

Armor

Hull HP 8,600 → 9,700 with hull upgrade, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are the exact in-game values, not estimated.

Hull (midship)	14 mm	7,300 (75% of HP)	Overmatched by 203mm+ (Furutaka)Angle bounces 152mm14 mm: HE pens from 127mm+	Largest HP pool. Citadel sits behind these plates; thinner deck and side plating absorb the rest.
Stern	14 mm primary (range 6–14 mm)	1,100 (11% of HP)	Overmatched by 203mm+ (Furutaka)Angle bounces 152mm14 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	12 mm primary (range 6–12 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.50 damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. Damage is gated by pen/over-pen multipliers instead (×0.50 direct pen, ×0.10 over-pen).
Superstructure	6 mm primary (range 6–14 mm)	300 (3% of HP)	Any HE ≥16 mm pens at full damage	Any HE ≥16 mm pens at full damage. HE-spam target, and the section saturates fast (often only a few thousand HP).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	4,900 magazine HP	Magazine detonation1–30% chance · below ~75% HP	Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster.
AA mount (8 mm mount)	separate HP pool, does not drain ship HP	200 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest AA on this ship. An AA mount destroyed at 0 HP stops shooting down planes for the rest of the battle; DCP does not repair destroyed mounts. HE shells specifically target AA mounts since the small-caliber HP pool falls fast.
Rudder (module)	separate HP pool, does not drain ship HP	2,900 module HP	Incapacitated at 0 HP	When module HP reaches 0 the rudder locks at its current angle until DCP repairs it. Repair via Damage Control Party.

Saturation cap = HP a section can absorb before further damage to it is reduced (the "bow-tank" effect). Citadel pool is ~165k on every ship (effectively no cap); damage is gated by pen/over-pen multipliers instead. Superstructure saturates fast but HE always pens regardless of the plate thickness. Rudder (and other module HPs) are a separate pool from ship HP: damaging a module doesn't drain ship HP. Incapacitated modules like the rudder and engine are restored by DCP, but secondary and AA mounts destroyed at 0 HP stay out for the rest of the battle.
