As the name suggests, solving this puzzle requires the use of multiple different methods of translation. The symbols used indicate the pigpen cipher.
This gives us IV XV XX / IV XV XX IV I XIX VIII / IV I XIX VIII, which observant solvers will recognize as Roman numerals. Translating to our modern Arabic numerals gives 4 15 20 /4 15 20 4 1 19 8 / 4 1 19 8.
From here, the numbers can be replaced with their corresponding letter of the alphabet (A=1, B=2, etc.) to get DOT / DOT DASH / DASH. The best-known cipher using dots and dashes is Morse Code. Translating . .- – gives the word EAT, which is our answer.
