One last suggestion for Ace In The Hole
As someone who often tries to make item perks work, the improved Ace in the hole is a great tool! I love seeing the recent buffs to item perks, but I feel like some small tweaks would really cement them as interesting picks.
While I'm not expecting a super powerful perk from ace in the hole, I feel like it can still falter compared to something like Dramaturgy, which can spawn an item with any add-ons (not rarity capped like Ace) by pressing a button, something you can even do while working on a gen. While situational and chance based, this is a MUCH smaller time investment for what can often be a bigger payout.
I think for the time investment of finding and opening (or rummaging) a chest, having the second add-on be very rare or lower rather than uncommon would be perfect.
