[Autumn]

Currently the method that is used to retain spirits (an intentionally risky mechanic) is to use a Frost-Dog's collar available from Ghost Dogs in the Crypt of Duyuei or in Castle Dungeons in the Great 6.

When equipped the Frost Dog's collar deals 2 ice damage each round and prevents you from losing spirits when dying.

Additionally allow me to share some insights that will allow you to restore your status faster when it comes to spirits, given you're on Korvara here I will ask that you check the following locations for spirits:

-The Graveyard in Telegrad/Duyuei Highway, and below that is a cave that leads into a crypt, each of these can contain some spirits.

-The Graveyard within Telegrad itself, top right of the map (Accessible from the back of town) was littered with a LOOOOOT of spirit locations, nearly up to probably around 10 spawns.

-Try carrying around "Pies of Forgetfulness" so that if you encounter a Mass of White Spirits, you can reset your skills and only acquire the ones you want spirited.
(For the unaware, masses of white spirits will only give ranks to skills you own, so a common trick is to reset your skill points when finding one, and purchasing only the skills you want to spirit, and then re-doing the rest of your skills.)

-Being prepared for death is very helpful as well, buying potions, knowing when to run away etc.

I hope all this helps.
