Fraction: Imposter
Skills: Conjurer can cast curses on other factions, and those who are cursed will die after a while. Everyone can see the curse.
In early games, conjurer is recommended to team up as soon as possible(unless the teammate is janitor since janitors are easy targets after cleaning up bodies). After grouping, sabotage the electricity first and pretend to go to electric room to repair. When space crews are about to fix, cast the curse as they are attempting to fix. Space crews are likely to scatter to complete tasks when the lights are on again and they'll have no clue by then who was cursed, when fixing electricity. So that will be a very convenient 'First Blood'.
If 2 players are fixing electricity in the above circumstance, stay calm and curse a player right away and your impostor teammate should be able to kill the other one at the same time. This calls for teamwork, of course. Otherwise, the other space crew might report the body if that impostor teammate didn't do anything.
How to Conjurer - Advanced
For all Impostors (With Joker): Curse whenever you can and jump into vent right away. If someone sees you using the vent, just tell them you're a joker! Because when space crews are not 100% sure of what you are, they will not vote our jokers right away. That's when you can tell space crews you can help them to find imposters, and the real space crews are very likely to skip voting. Those who still vote you are very likely to be the real joker, your very next target. Curse those who voted you and then you can impersonate the real Joker and cast curse as many times as you wish.
Conjurer's Helpers: Joker (you will impersonate as them), Space crews (tell them you're the joker and they won't vote for you easily.)
Roles that counters Conjurer: Sheriff (they can attack you when vulnerable)
