Okay, I'll talk about an adjustment first. It was an arguement between me and friends. And I got a result from it.
Town
Sheriff - Will now sees their faction (Town, Mafia, Coven, Neutral or Unknown). Unknown including some hard roles to prove (Vig, Med, BG, Etc.) some basically suspicious on Sheriff (Serial killer, WW on full-moon night) Add some evils that cannot be detected (Godfather, Coven with necronomicon) and Framed roles (Framed, Hexed but not doused) Doused will be found as Neutral.
Trapper - Sometimes, it takes too long to build a trap. The time will be reduce every times people died. (1 night for 15-7 members and require none to less than 7)
Mayor - Reduced vote to 2, but able to be whispers in limitation. (Prevents people finding bitten mayor by whispering) Mayor has a night ability to cause a 2 persons getting vote on next day which only happens once per game.
Investigator - Juggernaut will now be on the list. (BG, GF, Arso, Crus or Jugg) Also, investigate results must be change for covens to easier to claim. (Example - LO, Forger and Cl. which is dumb. )
Retributionist - After revived anyone, you will be his/her Guardian angel with 1 protection. (This doesn't mean you will change to survivor with no vests after target died but only has GA's ability)
Medium - Medium is now unique. They have ability to use 1 dead person to look over you. They will be told if you are visited. (This prevents people from getting bored and give seance power to becomes more powerful)
Mafia
Ambusher - Only person who get killed by you learns your name. Others are just noticed that their targets got ambushed.
Disguiser - Able to change mafia's role. Only if they're not unique. You may change yourself. Two uses per game. (This role becomes unique)

Neutral
Survivor - Changes vest to "get a cover". Changes limit from 4 to 3. Getting a cover when attacked, attacker will recieve "You are unable to find your target!". Get a cover makes you learn your attacker's name. This prevents from any visits or attack. (Even arsonist or pestilence!) This makes you easier to prove yourself (But hey, you're not alone to be undercover )
Jester - At night, choose someone to roleblock them for the rest of the game. This will not count as visit. If they die you will get your uses back. Only 2 uses per game.

Guardian Angel - "Purge" able to remove any effects. (Blackmailing, hypnotising, controlling etc. but not transporting)
Arsonist - Not astral anymore. But able to douse 2 persons at one night.
Pestilence - Changes the whole ability : Infects person (Works like old infection), Then click at yourself. Instantly kill people with powerful. People able to know if they are infected. (Or make a new role for this)
Coven
Hex Master - You gained undercover effect. Which prevents you from being visited or attacked.
Poisoner - Less person alives, the poison gets stronger. (less than 7 persons will instantly kill people)
Necronomicon - Change an order from CL > Necro > HM > Poi > PM > Medu to CL > Necro > Medu > PM > Poi > HM
