You've pulled your share of all-nighters keeping up with a busy ship, and it shows. You are more prepared for anything the void might throw at you, the crew seems to hang on your every word, and the safety of a million spinning worlds is on your shoulders. You've got this; All you have to do is breathe. You gain proficiency with Water and Spelljamming vehicles. Proficiency with Spelljamming vehicles covers a wide range of options, from sea-based ships with helms installed to purpose-built spaceships that were meant to fly. Proficiency with vehicles grants the knowledge needed to handle vehicles of that type, along with knowledge of how to repair and maintain them. In addition, a character proficient with Spelljamming vehicles is knowledgeable about anything a professional sailor would be familiar with, such as information about wildspace, the phlogiston, planets, spheres, tying knots, and assessing safe harbors. During each Ship Action combat phase, you can perform two total ship actions from two ship roles rather than one. The same action cannot be performed twice in the same ship combat round. These ship actions may be selected from different Stations. You automatically succeed on any Ship Shaken critical hit rolls to avoid being knocked prone. You have advantage on all concentration checks against Spelljammer Shock. Damage to you from the Deck Crew Damage or Interior Crew Damage critical hits is reduced to 0.
