Vampire Survivors

Miang is found in the coffin in Mount Moonspell. Once unlocked, buy her and survive on any level.

Miang Moonspell is found in the top right corner of Mt. Moonspell in a Coffin inside of a building. Then purchase her for use in the character select screen.

This achievement requires you to survive until there are 15 minutes on the clock. The easiest/fastest way to do this is to do the "Il Molise" (which has unmoving enemies) on hurry, to reduce the time required to 7 and a half minutes instead of 15. At the same time, you should evolve the Silver Wind weapon by combining it with a max level Pummarola to unlock Menya Moonspell and another achievement.

TLDR:
Character: Miang Moonspell
Modifiers: Hurry (and any others)
Objectives: Survive until 15 minutes, evolving the Silver Wind with max level Pummarola, then quit from the menu

I recommend you use the same strategy for three other achievements:



I recommend that you use a different map for the characters that require 100,000 kills in one map, as it would be extremely slow here.
