Defender's Crest

Defender's Crest is a Charm in Hollow Knight. It spawns damaging clouds around the Knight.

Usefulness
The clouds are not very powerful and have very little range, making it situational. Useful when fleeing enemies, as the clouds linger behind the Knight and damage pursuing enemies. It can be very useful during both the Broken Vessel and Lost Kin fights since the cloud can kill the Infected Balloons with one damage, so the Knight can focus on the boss and gain precious healing time. It also damages Oomas, triggering their explosion. As such, it is best to use caution when traversing Fog Canyon with this Charm equipped.

Costing only one Notch, it is most effective when used with one of the other Charms listed below, as it greatly increases their power.

Wearing Defender's Crest unlocks extra dialogue with Elderbug, White Lady, Relic Seeker Lemm, Dung Defender, Leg Eater, Tuk, and Divine. Additionally, it unlocks the following interactions:
 * Leg Eater gives a 20% discount on his items and repairs
 * Relic Seeker Lemm refuses to barter
 * Tuk gives a free Rancid Egg

How to Acquire
Reward from defeating Dung Defender in the Royal Waterways.

Trivia

 * Wearing Defender's Crest attracts small flying bugs when in the Pleasure House kitchen.
