[Skill] Defiant Shields: A new Imperius Tier 4 skill that increases drone resist all. [Skill] Robust Core: A new Xinthu Tier 4 skill that increases drone hull. [Skill] The Xinthu skill "Auto-Summon" has been replaced by the skill "Tough Shell", which increases drone resistance by a percentage. [Balance] Several changes to max skill points for a skill. For example, it is now possible to spend 5 points in the Imperius skill "Strong Drones" (up from 3). [Balance] Several changes to skill dependency requirements. For example, the Imperius skill "Warp Plasma Storage MK2" now only requires a single point in "Warp Plasma Storage MK1". [Balance] The radius of all Booster-type weapons has been increased. [Misc] The interaction distance to doors has been reduced for larger ships. [Misc] All passive drone summoning auxiliary items (e.g., all Fighter Hangars) now support weapon mods. [UI] Added a tooltip for invalid item modifications. [Bug fix] Fixed a few typos.
