I really love the Guardian Angel role and every time i'm Guardian Angel i either get Blackmailed or Poisoned (When Poisoner has Necronomicon it's even worse)
So my idea was to make the Guardian Angel immune to Blackmailing and Poisoning,
it is really annoying when you have to focus on other things (like calling for a Doctor or showing the town that you're Blackmailed) during the day gameplay instead of doing your utmost best to protect your target from either getting killed at night or getting lynched during the day.
It would also be nice to be able for a Guardian Angel to protect 3 times instead of just 2 times during the game
Quick summary
Guardian Angel:
1: Immune to poisoning
2: Immune to blackmail attempts
3: 1 extra protection/purge, instead of 2 protections/purges you will have 3 protections/purges
