Yeah, it's a bad decision to choose Flash games for BotD. This makes it impossible for users who haven't earned the badge yet to claim it. They will lose out on Points and Kongpanions through no fault of their own.
Beclutcher Party: Full Lv 10 Epic Armor +10, max single target damage. Forget about buffs, healing and defensive skills. Beat him with Beorn, Zoey, Neve, Revere. Skills were Revenge, Catastrophe, Icy Embrace, Better than Good. All Lv 7 Powerful Trinkets. Beorn's Revenge helped him stay alive long enough, was last man standing with about 2k HP left. Good luck!
The Museum's major flaw is that at one point it will become too time- and resources consuming to upgrade what it's supposed to do: Ironically, to reduce the amount of time and resources to craft gear. Also, once all of your chars are decked out in Lv 10 Epics (excluding Trinkets), the Museum becomes practically useless and you might as well set AutoSelling to All, since all there's left to do is to Forge your epics to +10 (not all of them, just 4-6 Sets), also an extremely time- and resources consuming process. BTW for the players who are already at Lv 10, the Boxing Gloves will give you the best idle bang for your idle time, 228.729 Gold per Second to be exact. So if you want to maximize your idle gold earnings, put up 4 Boxing Gloves and 1 Bloopinator, then Auto-Sell: All.
Museum is intended to be a longer term goal, and when we implement our plans for an ascension system it's progress will carry over forever. It's NOT intended to be a system you complete before you beat the t10 boss.
My strategy for Goblin King was Beorn, Neve, Zoe, Alok. Everyone was in full Lv 9 Epics, +7 Enhancement for Beorn and +6 for everyone else, on every piece. Every char was fully upgraded and the skills were Revenge, Rain Fire, Blizzard and Song of Strength.
You should really consider lowering the mats required to upgrade items through the Forge. Right now it takes 850 Mats (25+50+75+100+150+200+250) to upgrade just one item to +7 and it will take another 300+400+500=1200 mats to upgrade one item to +10. That's 2050 mats total. More than two full inventories.
Hello! Museum reward structure was changed with this patch - completing a "set" of rarity contributions for an item (so all ten forges + base item) will give a fixed reward based on the rarity contributed (craft speed for commons, proc chance for higher rarities) that apply to the item type.
So turning in a full set of forged common knives will give 4% craft speed boost to all knives (even the t10 knife, bloopinator!)
Hello! Museum rewards are bugged and are reworked for the next patch (which will include Boss 9 and some QoL fixes). It's currently in testing with Patreon supporters and should be out next week!
BotD is working but you won't get a popup message that it has been rewarded anymore. Wait a couple of seconds, then go to your profile to see if the badge has been checked for today. To be absolutely sure, also check your points.

There's 10x less floors now to complete so you should get there faster. In addition, there will be a feature next patch to assist in this.
