Dull

Dull is a negative trait — cooldown penalty with no offsetting bonus. Reroll immediately.

Why reroll

Dull is the inverse of Timer, the CDR specialist. It sits at the bottom of the FRVR tier list with no recommended ability pairing, and Rolasyum’s matrices (Reaper for Raid, Flash for Survival/Infinite) name no D-tier negative.

Tier positioning

Dull is rated D by FRVR and grouped with Slow, Weak, and Fragile as the four negative traits.

Reroll guidance

The reroll mechanic uses a Trait Spin (see Slow for the reroll workflow). Target outcomes: Flash (Survival/Infinite) or Reaper (Raid); any Legendary (Hunter, Destroyer, Master, Zombie) is a good bridge.

Synergies & comparison

Dull has no positive synergy with any ability. Its CDR penalty is the inverse of what high-cooldown abilities need — pairing Dull with Nen Prodigy or Sosuke (the two CD-heavy abilities that need cooldown upgrade allocation) compounds their already-slow rotation. Replace Dull with Timer as a B-tier CDR alternative if Mythic traits are not yet rolled, or push for Flash, which carries +20% CDR alongside +20% DMG.
