Golden chests reward players who arrive without healing
A golden chest only opens if you reach that spot without using a healing item since the last checkpoint; dark chests, on the other hand, need to be hit while they regenerate health - you have to deal enough damage before they close back up.
Give up a feather or two to hit harder
Every feather removed from your loadout boosts all the damage you deal by 10%: you risk having fewer heals available, but against a boss you already know well, dropping to one or two feathers can be worth it to end the fight faster.
Dying only costs you one healing item, not your experience
Death in Death's Gambit doesn't wipe your earned experience points. Instead, you lose one healing item and drop a feather right where you died, which you can recover by going back there.
Always keep a bow equipped
Even with two melee weapons equipped, it's worth carrying a bow: some bosses step out of melee range to unleash AOE attacks, and in those moments only a ranged weapon lets you keep chipping away at them.
Use Crystal Bombs and Abyssal Eyes to explore safely
Crystal Bombs deal heavy damage against groups of enemies, while Abyssal Eyes let you scout threats and secret passages ahead of time - especially useful in blind corridors that often hide a valuable chest behind a not-so-obvious platform.
