If your testing is showing that success rate is too low, what if we bumped up the table? That is, 19 or 20 means death, 18 wounded for a year, 17 innocent NPC killed (or, maybe, random player killed?) We would say that a natural 20 means that assassin completely evades detection, so that that particular assassin doesn't count against you for detection. Ex: You send five assassins, one gets a natural 20, so the target is killed and you only have to get > 3 to evade detection.
(( The issue isn't so much that success rate is too low (I'd say it's about right as-is), but the getting-killed-off-yourself rate is a bit too high. Personally, what I'd suggest is:
1 (w/o modifiers) -- Critical failure. Flip a coin.
Heads - The assassin turns on his target, handing full details of the plot to the Gendarmerie. The person who ordered the hit is instantly revealed, and no further dice rolls are made.
Tails - The assassin turns on his target and kills him. (This may result in both parties dying as a result, as other assassins could find and kill the original target.)
))
I, too, have grave concerns regarding the Veto And Ministerial Legislation Act. As far as I can see, it allows for a single party with 35% of the vote to command supreme power over the entire legislature.
Step 1. Have a party member elected President or Chancellor. Or ideally, have your party occupy both positions, either by forming a minority government, by making coalition promises or just through general popular support. (The NLPD have already achieved this on several occasions, so this stage is not unrealistic.)
Step 2. If President, make it clear that one will veto any and all proposed legislation except that which you (or the Chancellor) personally provide. The rest of the Reichstag can only command 65% of the vote, so any override or Vote Of No Confidence fails.
Step 3. If Chancellor, suspend all ministerial positions, and gradually set oneself up as absolute dictator. This stage may require finesse or persuasion, as one will need an extra 15% of the Reichstag to agree to not override the suspensions. Theoretically, one should begin with the Commander of the Gendarmerie and the Minister of the Interior while the Reichstag is not unduly suspicious, and then threats of arrest or military force can be used to gain the continued support of the 15%. Once all ministerial positions reside in one body, the 15% is no longer required, as all Votes Of No Confidence will fail to reach the 66% threshold.
Step 4. Repeal elections, declare oneself Dictators For Life. Enjoy your newfound supreme authority, and beware the Ides of March.
But even if we were to amend the Act to remove specific means of exploitation, the general principle of the thing - handing more power to the President and Chancellor, at the expense of the Ministers and the Reichstag - is one that I must unconditionally oppose. And I am extremely surprised to see it proposed by a liberal federalist party; I thought you fellows were in favour of decentralisation of governmental power?
