This is a reupload of my old guide from oktober 2019. Since the cleansing of the forums it had also gotten removed, so figured might aswell reupload it. Hope you enjoy!
edit - i left out the Arclight method, which is arguably better. Regular accounts can buy an Arclight from the shop, ironmen cant. If you dont have ancient shards in your bank its probably not worth farming them specifically for Kril.
