PoliHas Favorite Item

A Water Code, Burst stage 2 (B2) Defender Shotgun Nikke.
She supports survival with a shared ally shield and Increased ATK, plus Increased DEF and Equally shares damage taken aimed at low-HP allies.
She is rarely a main pick, but works well as early-to-mid game survival support or a substitute barrier.

Brave Call grants all allies Increased ATK every 5 normal attacks.

That's a Good Boy applies Increased DEF and Equally shares damage taken to herself and the 2 other allies with the lowest remaining HP.

Poli's Defense Line places on herself a shared ally shield based on the caster's final Max HP and grants all allies Increased ATK. Her Burst cooldown is 40 seconds.

When That's a Good Boy is off cooldown, use it right when a low-HP ally is taking focused fire.
Use Poli's Defense Line right before big damage comes in to stack shield and Increased ATK.
Leave basic firing on auto and only manage Shotgun engagement range manually.

Manual input required

Build around Shotgun range play and reload and Max Ammo support. If Harmony Cube levels differ greatly, prioritize the high-level cube.

Her shield scales with final Max HP, so reinforce survival with DEF and secure buff contribution with ATK.

Poli's Defense Line's shield size scales with final Max HP, so Burst investment is relatively worthwhile. Overall skill book priority is low, so many stop at 4/4/4.

Based on recent guides and tier data, she is rarely a main pick. Her shield, Increased ATK, and damage distribution are considered for early-to-mid game survival support or as a substitute barrier.

Poli's Defense Line applies a shared ally shield and Increased ATK at once.
That's a Good Boy applies Increased DEF and Equally shares damage taken to low-HP allies, reducing burst damage spikes.

Her Burst cooldown is 40 seconds, leaving long gaps in shield and Increased ATK.
As a Shotgun, her engagement range is narrow.
In the current meta, she is lower priority than top barriers and buffers.
