Maybe fifty could be replaced by half or something ?

For consistency and readability, I think that is it better the way it is.

Consistency because we use percentages for other, similar amounts, including -20% on the same string. To keep consistency, switching 50% to ‘half’ would require changing 20% to ‘a fifth’.

Readability because numbers are easier to spot than words when scanning a string for amounts. And readability is important in all strings that provide players with information relevant to the game (as opposed to strings that do not affect the game, such as those covering historical background).

Successful build - Chance fights ever on the side of the prudent.
