White Rum — Review & Analysis

White Rum

White Rum is an Intellect AoE DPS: both her Skill 1 and Ultimate hit every enemy with Reality DMG, making her a solid wave-clearer. Her signature is positional play — Skill 1 retreats her backward, and when the Ultimate fires she charges forward, gaining more damage the farther she advances while stunning the whole field. Her clear role is an AoE sub-DPS with built-in crowd control.

Strengths
  • Both Skill 1 and the Ultimate are AoE Reality attacks, clearing multiple targets at once very efficiently.
  • The Ultimate stuns all enemies for 1 round; if she advances at least 3 positions it also ignores 50% of Stun Resistance — a valuable control tool.
  • Strong positional synergy: Skill 1 retreats her, and the Ultimate gains +15% DMG per position advanced, creating a stack-then-burst loop.
Weaknesses
  • The Ultimate can only be used while in the Boarding Assault state, forcing a setup turn of Boarding Prep before she can burst.
  • Her Intellect afflatus stands outside the counter cycle and she sits at tier C — her ceiling and flexibility are limited regardless of enemy Afflatus.
Build Priority

Prioritize the Ultimate first, since it is her main AoE damage source with a full-field Stun and a distance-based bonus; then raise Skill 1 to boost wave clear. As a pure offensive AoE DPS, favor attack-oriented Psychubes (ATK, crit rate/DMG, or damage amplification) over healing ones to maximize her burst.
