And here's a build without using any of Power of Love / The Lovers / Blank Card, maintaining the previous rule on non-canon Curses or Remittances:
Player (Myself)
Break Containment (Combat-Class) (-16, -1, +3)
Curses (Major): The Geas of Indenture, The Sign of the Crab, The Affliction of Slumber, The Geas of the Sanctum, The Doom of the Tyrant, The Plenary Brand (+18)
Curses (Lesser): The Doom of the Sailor, The Doom of the Addict (+2)
Remaining Remittance Value: +23 - 17 = (+6 RV)
Primary Remittance: Wands (The Flow, Redolence)
The Flow: Freedom (Quality), Quality, Expertise (Quality) - Maximize the Cursebearer's inherent strength of essence, though can also be used on its own to improve the quality of the character's actions/tools or reduce that of his enemies. By my reading it should be able to be used both to augment the potency of essence increase (via the World), and diminish the profundity of essence decrease (from Expenditure). This is an incredibly useful power, basically Amplitude (Metaphysical) so long as you're targeting something with a rate of change.
Redolence: Expend, Paper - Utilize that strength of essence for incredible power. Hopefully The Flow has invigorated the Cursebearer's essence to the degree that ruinous losses for others are merely serious for him. Expend greedily, but not recklessly, to permanently acquire broad, highly effective superpowers relevant to the Cursebearer's situation.
Lesser Remittances:
Item: Justice - Halves the cost of Expenditure on top of being a potent status bludgeon. Also grants a warning system if the character would perform an Expenditure that's over the line, as that is a major decision the Accursed would disapprove of.
Item: The World - Naturally restores / augments the wielder's essence, as well as possessing immense synergy with The Flow (Quality)
Refinement: Temperance - Reduces the negative consequences of Expenditure so long as the character makes a forthright and energetic effort to mitigate their Curses
Refinement: The Tower - Guarantees that the character will fully recover from any given Expenditure over time
Companion: The High Priestess - Synergizes highly with The Flow (Quality) and The World, massively enhancing the productive magical output of her society and providing a civilization with which the Cursebearer can more or less safely interact.
Companion: The Emperor - Maybe he can produce essence-boosting foods? The Flow (Quality) applied to his other buffing foods should render them extremely potent regardless. An army of thousands augmented by a Flow-boosted World, fed on Flow-boosted Emperor foods, and wielding Flow-boosted artifacts should prove a decent deterrent to attacking the slumbering Cursebearer.
