Unlocks pivotal power boost, letting core skills hit higher ranks sooner.
These Bell upgradesform the backboneof advanced Hell Clock strategies. Starting with base damage and cooldown speed ensures every skill hits hard and often. Enlarging your relic capacity lets youcombine powerful buffswithout sacrificing flexibility. Extra timer and chance for Red Portalsunlock more loot potential, while Second Wind gives that crucial margin for error.

Enablesmore floor skipsfor faster farming and deeper runs.

Useful for more sustained fights when healing items are in use.
Conviction Gain
Adds five to seven point five percent Conviction per Mana spent
Great for shield buildswith Closed Body or resistance-based defenses.
A Tier upgrades may not be spectacular, but they’re stillvaluable in runs. Upgrades that boost Soul Stone gain, cooldown speed, or attack rateimprove your efficiencywithout depending on rare relics.
Mana is agating factor early on, so get upgrades and skills thatincrease your manaregeneration and capacity.
Others buff flexibility byincreasing relic drop chancesor lowering upgrade costs, and healing boosts and Conviction generation also improve survivability. When timed well in early or mid game progression, these upgrades giveconsistent returnsthat round out any build.
Potion Capacity
Grantsone extra potion chargeper rank
More healing capacity helps sustain longer fights, but its value depends on potion usage.
Experience Gain
BoostsEXP gainby five percent per rank
Faster leveling is nice, but once you stop gaining levels, the benefit slows down.

Increases movement speed by two point five to five percent
Helps with mobility and dodging, though raw damage or survivability nodes often matter more.
Blessing Reroll Discount
Reduces the cost of redrawing Blessings by ten percent
Saves goldand improves options, but not essential if your build already feels tight.
Blessing Banish / Banish Amount
Lets youbanish unwanted Blessingsand increase banish charges
Cleans up poorer Blessing options, though niche for players who tailor builds strictly.
Trinket Drop Chance
Adds ten percent chance for Trinket drops
Trinkets can help, but they’re often secondary to Relics and not core to build strength.
These B-Tier upgrades arestrong in specific scenarios. If you rely heavily on potions or finish many runs with leftover gold, Potion Capacity or Blessing Reroll Discount may punch above their weight. Movement Speed improves both offense and evasion, but pales compared to offense or defense nodes.
Meanwhile, cleaning up Blessings or increasing Trinket drops canhelp tweak builds, but they aren’t really important in most runs. They shine best whenpaired with stronger core upgradesfrom S or A Tier, or used when your run needs just one extra edge.
- two percent Physical Resistance per rank
Fire Resistance
- five percent Fire Resistanceper rank
Limited tospecific damage types, and rarely critical unless that element is dominant.
five percent Lightning Resistance per rank
two point five percent Plague Resistance per rank
Nice in later runsbut irrelevant early, and timing limits opportunities.
Starting Blessings
Begin runs withan extra skill Blessing
Good if you need extra options, but depends on Blessing availability and your early build.
- twelve percent Soul Stone gainwhen recycling Relics
Adds passive gain, but recycling rarely beats regular run earnings.
These upgrades aredecent QoL additionswhen your early S and A Tier core is locked in. If you find yourself withextra Soul Stonesand no essential upgrade left, selecting one of these for passive utility can be a fine choice. You can also lean into resistance upgrades on maps witha lot of elemental damage, but most runs fare better focusing on stronger, more impactful nodes.
- ten percent chance to find Blessed Gear
Rarely benefits most builds. Blessed Gear issupplemental and often redundant.
Blessed Gear Discount
Reduces Blessed Gear shop cost by five percent
Only helpful if yourely on Blessed Gearextensively, which most players do not.
Red Portal Intensity
Skips an extra floorwhen using Red Portals
The frequency of Portals matters more than the floor skip count.
Begin runs with 500 Gold
Most of your goldcomes from floor runsand merchant discounts later.
These upgrades provideminor bonuses or impact effects that rarely contribute meaningfully to your run’s power curve. In nearly all scenarios, there’s amore impactful choice elsewhere: whether improving defense, scaling skills, enhancing relic economy, or increasing time and survivability. Only consider these when you’retruly out of other options, and even then, only choose if one fits your exact build needs.
