What should I be to gamble Sander's Paragon

To gamble for

Sander's Paragon (Sander's

Cap)
in Diablo 2 Resurrected, you should use a character around level 20–25 to ensure the item level (iLvl) is high enough to spawn the set item, but low enough to keep costs down.

Optimal Level: Approximately Level 20–25. The

Cap has a low Quality Level (qLvl), and gambling at this stage prevents it from rolling into higher-level, more expensive, or exceptional/elite versions.
Item Type: Select Caps in the

Gheed gamble menu.
Item Level Calculation: Gambled items have an iLvl of Clvl +4/-5. To ensure the

Cap can roll the set version, your character must be at least level 15–20 to hit the required iLvl 20.
