does it work if i put one of the starter weapons in my backpack

@TehStrangeWizard the secret starting weapons. You only need to hold one of them until the end and you're allowed use the forge on it (bonus: reforging is free!)

For the fourth one, do you need to beat the game with the weapons that you started with regardless of what they are, do you need to beat it by using the secret starting weapons right next to where you spawn, or can you beat it by setting all drops in custom mode to the starter weapons?

Someone needs to get "I like to live dangerously" on five boss cells

@Hak, while it seems you have succeeded in my absence, I believe the set up I chose was a tactics build with an infinite ammo or quick bow (preferably with a max XP or triple damage bonus), a cursed sword (since at this stage, perfection is mandated), light speed to dodge certain attacks, and corrosive cloud for extra chip damage. With a cursed sword, assuming you've learned the moves, you should only have trouble in the last phase where the health bar matters. I think the mutations I had were ripper, caltrops, and another I can't remember (potentially the dodging slows enemies one). If you end up doing it again and don't have a better method, hope this helps!

@Terminus_X do you mind sharing your ideal setup for the flawless Collector? I've grinding it for a while now. Thanks in advance.

@Terminus_X; I'll try and get round to it at some point. Busy at the moment on the weekends as its December.

Can now confirm the two new hidden achievements are unlocked by flawless runs of the Giant and the Collector. Hopefully, since I've been playing the game all... day... I can get some rest now...

Hey there, there's been another achievement update. The only two new ones are hidden achievements for beating the Giant and the Collector without taking damage.

@Enormous Ah, I get what you mean now. "Go to town" is a colloquialism for "go crazy" or if you want the implied meaning "hurt things a lot quickly". Hope this helps!
