Assuming the encryption rating is the rating of the encryption programm (there is no "encryption action" as stated on page 256) the hardest encryption would be 6. Even if you use the house rule that allows only "skill" rolls in an extended test, the treshold of 2*6=12 can be cracked by a 12 year old. If you have 5 decrypt, 4 response you get to roll 9*5 = 45 dice, that get you 13 hits on average. If you dont use the house rule, but the optional rule that allows "dice" rolls you only need a combination of response and decrypt that adds up to 7. giving you 7*7=49 dice for an average of 14.33 hits. If you dont restrict extended tests at all your 1 response 1 decrypt script kiddie is hacking your beefy rating 6 encryption in 18 combat turns which is about one minute. Did I overlook something? |
