Unjester Bulletproof N3-N4 Weak Checker D5 Suicidal
Unjester (alignment): You win and leave the game if you die by any means other than the daily elimination. You lose and leave the game if you die by the daily elimination. You lose if you are still alive when the game ends. You do not count as a threat for purposes of determining factional victory.
Bulletproof: You cannot be killed during the Night unless the killing effect is Strong, Unavoidable, or otherwise ignores defensive abilities.
Checker: During the Night you may investigate one living player. You will receive a result of "No result" if anything stops you from performing your check; otherwise, you will receive a result of "Check successful."
--N3-N4: You may only use this ability if it is N3 or N4.
--Weak: If you successfully check anyone who is considered to be a threat to the Town with this ability, you Unavoidably die.
Suicidal: When this ability triggers, you lose and leave the game.
--D5: This ability will Unstoppably trigger on D5.
Triggering "Suicidal" does not count as a death for purposes of fulfilling the Unjester win condition. Reroll if any role that can manipulate the flow of time is present; reroll if any role that globally prevents actions from being taken is present. Moderator is encouraged to change the numbers for the N3-N4 Checker or the D5 Suicidal if the game-size is unusually small or large; Suicidal should trigger immediately after Checker is no longer usable.
I'd see if there was a way to make both effects work somehow, or if there's a loophole. In a case of "1-shot Invincible Cycler" vs. "1-shot Force of Nature", I'd say the 1-shot Invincible Cycler survives until their protection runs out - and then they die. If I could foresee an impossible reaction and no workaround during pre-game, I'd force re-roll whichever role looks more unbalanced. If I failed to foresee, then whichever role did a better job of considering things that could cause problems and providing workarounds would get the nod.
I'd consider modkills to fall in the category of a "You lose and leave the game" effect - at least in a game where people could be brought back to life. Any role that tried to overrule that clause would be re-rolled if I were the one doing the modding.
