Esper Ability upgrades cap early in a character's life cycle. Dump excess C- and B-grade materials on mid-level skills instead of waiting for a late-game breakpoint that never arrives.
Houdinii's Schemes is the daily domain for skill-upgrade materials. Set a reminder: missing a day means losing a meaningful chunk of weekly progression.
CO is stocked on the Hunter Exchange, so an extra copy is always a Fons purchase away when you fall short.
If RNG is against you, craft a CO from 3 x FNG. Crafting is deterministic, so it is a reliable fallback when a deadline is near.
