EX Battle-Tested Guardian Training

is a level 57 HWAoC: in, added in the DLC pack.

Overview
HWAoC: is a HWAoC: that can be completed using only HWAoC:. When completed for the first time, HWAoC: receives a reward of two NaN Giant Ancient Cores, fifteen NaN Razorclaw Crabs, and a random HWAoC:.

HWAoC:'s objective is to defeat 500 NaN Enemies within eight minutes. All of the NaN Enemies are NaN Black Bokoblins at first, and more spawn when HWAoC: reaches 50 K0s. At 100 KOs, a HWAoC: also spawns a short distance from HWAoC: and starts moving towards it. Another one spawns at 200 KOs and does the same as the first, although it spawns further south. When HWAoC: reaches 300 KOs, a large group of NaN Black Lizalfoss spawns, along with another HWAoC: that spawns in the southern area of the map and moves toward HWAoC:. More NaN Black Lizalfoss spawn at 350 KOs. At 400 KOs, a HWAoC: spawns in the eastern side of the map. Once 500 NaN Enemies are defeated, the time limit is taken away and HWAoC: must then defeat each HWAoC: that spawned and is still alive. The HWAoC: ends once every HWAoC: is defeated.
