ASPD & Cast Time

Speed mechanics: how fast you swing, how fast you cast, how soon you can act after.

ASPD — Attack Speed

  • Soft cap commonly around 190+ [VERIFY current cap in RO M]
  • Higher ASPD → faster auto-attacks → more DPS for crit / auto-attack builds
  • Inputs:
    • AGI (primary)
    • DEX (secondary)
    • Weapon class base ASPD (daggers fast, two-handed slow)
    • ASPD% buffs (Two-Hand Quicken, Adrenaline Rush, etc. [VERIFY])
    • ASPD-flat cards (e.g. Whisper card on garment [VERIFY])

Breakpoints

ASPD has diminishing returns, with values that “click” into the next attack frame. Find the next breakpoint above your current ASPD for your weapon class — that’s the target. File breakpoint tables per weapon when you confirm them.

Cast time — three components

RO M splits casting into three pieces. They’re tuned independently.

VCT — Variable Cast Time

  • The reducible portion
  • Reduced by: DEX (primary), INT (secondary), buffs (Suffragium, Magic Strings) [VERIFY]
  • Sketch: VCT_actual = VCT_base × (1 − reduction%) [VERIFY]
  • Hits 0 at sufficient DEX/INT — common goal for casters: instant cast

FCT — Fixed Cast Time

  • The non-reducible portion
  • Reduced only by FCT-reduction sources (specific cards, runes, gear, certain skills [VERIFY])
  • Even a small FCT (~0.5 sec) breaks “instant cast” — plan for it explicitly

ACD — After-Cast Delay

  • Cooldown between successive casts
  • Reduced by ACD% sources (specific cards, runes, set bonuses)
  • Different from per-skill cooldowns, which are skill-specific

Practical implications

  • Caster goals: hit instant VCT first, then push FCT and ACD
  • Auto-attacker goals: hit ASPD breakpoint for your weapon, then stack ATK
  • Skill-spam hybrid: usually ACD-limited, not VCT-limited — don’t over-invest in DEX past your VCT target

Common gotchas

  • ASPD potions / buffs can push you past a breakpoint temporarily — useful for burst windows
  • Weapon swap changes base ASPD → effective ASPD changes too. If you swap weapons in combat, plan around both states
  • Cast animation lock: some skills lock you in animation regardless of reductions; those need FCT-reduction to “feel” instant
  • Mounted state: some classes have ASPD penalties / bonuses while mounted [VERIFY]
