Where to Spoil Mithril Ore

There are two different numbers here, and they shouldn't be confused.

Chance in the spoiler — the probability that the desired item will actually be found in the mob's loot. This is specific to each mob and is listed in the table below.

Chance to apply Spoil — a separate value, depends on the skill level and the target level: basic 80% are multiplied by the ratio of your Spoil level to the mob level, and if the mob is more than eight times higher than the skill level, then an additional amount is removed. 9% for each additional level. Therefore, the table indicates what Spoil level to use against a specific monster.

What else influences? The numbers below are base numbers, exactly as they are set in the game data. In combat, a spoiler multiplier is added to them, which is set differently by each server. If you are significantly older than the monster, part of the chance is reduced by the "blue" mob rule: for each level above the allowed difference, a spoiler is removed. 9%, and at a large distance nothing drops from the mob.
