How Spiky Shield Works

Spiky Shield is a retaliation staple: it both raises your Armor and converts that Armor into Thorns damage. As your Armor scales, the reflected damage scales alongside it, letting melee swarms delete themselves on contact.

Tip: Armor from tomes, items, or character passives all contributes to the conversion. If you plan to lean into Thorns, prioritize reliable sustain so you can safely let enemies touch you.

Cactus (Thorns AoE)

Cactus fires spikes when you’re hit and scales with Thorns—perfect with Spiky Shield for hands-free crowd clear.

Quin’s Mask (Thorns Explosions)

Gives Thorns a 50% chance to explode on trigger, turning every contact into AoE. Stack Armor/Thorns to maximize proc density.

Aegis weapon

Aegis & Athena

Athena/Aegis thorns builds are community-favored: you’re tanky, stay close, and let retaliations handle waves.
