Vengefly King

The Vengefly King is an optional mini-boss in Hollow Knight as well as a Colosseum of Fools mini-boss. Unlocking its Journal entry requires beating 2 Vengefly Kings.

Hollow Knight
Vengefly Kings are the territorial patriarchs of Vengeflies and are native to Greenpath. One can be encountered above the roads of Greenpath, hanging on the ceiling and chewing on Zote. Harming it prompts to release Zote and to fight the Knight. Upon defeat, the Infection bursts out of it and makes it explode in pieces. Neglecting to help Zote results instead in the Vengefly King eating him before disappearing.

One more Vengefly King can be fought during the Trial of the Warrior.

Behaviour & Tactics
If it opens its mouth to Swipe, wait until it starts moving. Jump over it as it approaches. Either perform a downward slash to get in some damage or simply avoid it.

When it summons normal Vengeflies, kill them as quickly as possible. The longer they're around, the more difficult dodging the Vengefly King will become, and they provide an easy way to get SOUL.

There is enough time to heal immediately after dodging a Swipe attack.



Location
Vengefly King is first encountered at the north of Greenpath. It can also be battled in the Trial of the Warrior at the Colosseum of Fools.

Trivia

 * If the player decides not to rescue Zote, then they will miss out on fighting the Vengefly king in Greenpath and receive the "Neglect" achievement. However, the Hunter's Journal entry can still be completed when one is fought in the Trial of Warriors or in Godhome.
 * In Godmaster, the Vengefly King along with the Massive Moss Charger and the Soul Warrior appear as regular bosses.
