Building comparison
head to head
Diablo ImmortalvsDiablo IV
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Diablo Immortal
Optimization · Systems & Chaos
Blizzard's mobile Diablo where loot RNG and paid gem systems drive character power.
Diablo IV
Optimization · Systems & Chaos
An ARPG loot grind about chasing affix rolls to feed a damage-stack build.
Diablo Immortal leans Optimization (Systems & Chaos); Diablo IV leans Optimization (Systems & Chaos).
Diablo ImmortalDiablo IV
Axis by axis
Execution3 vs 3
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo Immortal
Touch-friendly combat with dodge timing
Diablo IV
Clicking and dodging are light; gear carries you.
Reads1 vs 0
Diablo Immortal leans a little harder on reads, though the gap is small.
Diablo Immortal
PvP battlegrounds exist but gear usually decides
Diablo IV
Enemies and bosses are scripted; no adaptive opponent.
Variance6 vs 6
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo Immortal
Legendary gem and loot RNG, heavily monetized
Diablo IV
Loot rolls, affixes, and uniques drive every session.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo Immortal
Resonance, paragon, set optimization dominate power
Diablo IV
Paragon, aspects, and damage buckets are solvable theorycraft.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
