The most enjoyable actions in X Wing are surely the Boost and Barrel Roll and the less obvious, but real life saver is the Evade. They do something that ties directly into flying, rather than endowing the ships with a “readiness” state token.
The Evasion kings, Imperial fighters need to use them to make up for a lack of shields.
First, a reminder of the Pilots or other elements that effect all or most actions in general;
Vader gets 2 actions with no strings!
Tycho gets actions even when stressed.
Lando gives a free action out after a green move.
Wes can strip tokens from his targets.
Advanced Sensors System upgrade changes the action/move order.
Dark Curse strips attackers of mods.
Emperor Palpatine allows any one dice to be modified per turn.
Contraband Cybernetics allow s you to take a stress for an action after a red move.
Manaroo allows token sharing with a friend.
Auto-blaster Cannons and Turrets ignore defence effects.
Now to Boosts, Rolls and Evades.
Rebels
In SC, the Rebels are weak in native Rolls (B-Wing & YT2400) and Boost/Evade capable ships (A Wing), but do have a couple of other options.
Jake Farrell gets a free Boost or Roll after spending a Focus (a true dare devil).
Luke can swap a focus for an Evade, guaranteeing the real benefit (his Force ability?).
R7-T1 gives a free Boost (and Lock).
R3’s can swap an unused Lock for an Evade, basically a “super Focus”.
C3-P0 can “guess aloud” how many Evades are rolled and add +1 if right (a “0” is always 1).
Jan (crew) can upgrade a friends Focus to an Evade.
Lando (crew) can roll 2 defence die and take any Evades.
Imperial
The Imperials are the real stars here, with only their two large base ships unable to access Barrel Rolls and the Interceptor also having Boost. Interceptors also feature predominantly below.
Juno Eclipse can change move speed after reveal, then Roll.
Turr Phennir can Roll or Boost after an attack.
Lt Lorrir gets banking moves with Roll.
Carnor Jax strips enemy of 1 Evade
Kir Karnos may spend Evade for an extra hit.
Ysanne Isard offers a limited Evade.
Agent Kallus can gain Evade against pre-chosen enemy
Scum
The Scum share with the Empire the only ship with both a native Boost and Roll, the Star Viper. The Viper also has the S-Loop and with Dalan, Talon Roll options as well making it the most interesting ship to fly (and look at?). The Scurrg and Jump Master may also Roll, matching the Tie Bomber and YT 2400 respectively. Their only other ship of note is the Firespray with an evade.
Kaat’o may steal a “friends” Evade.
So can Palob.
Latts Razzi strips enemy stress to add Evade to self (that minx).
Generic
Thrust Corrector can cancel 1 of your targets Evade.
Homing Missiles ignore Evades.
