The USS Relativity was designed for temporal experiments and now serves as the key tool against the Krenim faction. It's an Epic Grade 4 Explorer with 15 tiers, covering level range 42-70. It leans support rather than damage-dealer -- bring your heaviest hitters along and let the Relativity do the counter-play.
The Relativity has two exclusive active abilities, Anti-Charged and Anti-Static. They apply counter-states to enemies in battle. Only one is active at a time, but you can switch between them while not in cooldown. Pick the right one before you engage each hostile type. Per the source, Anti-Static Shift disables the temporal abilities of Charged Krenim Invading Entities and Formation Armadas, and Anti-Charged does the same to Static ones. No exocomp is needed to take on Krenim Invading Entities with the Relativity. Passively, Anti-Tachyon Weaponry increases damage against Krenim Invading Entities, and Relative Growth boosts the Encrypted Intelligence you earn from fighting them and their Armadas.
Relativity research covers warp range, cargo capacity, and hull and shield health for all ships. It also gives loot, damage and Apex Barrier bonuses against Krenim Invading Entities, and loot and damage bonuses against Krenim Formation Armadas. Building the ship unlocks DTI rewards: Ship Parts for upgrades, Static and Charged Tachyons to unlock its research, Artifact shards, a daily Relativity Claim of Static and Charged Credits that grows with tier, and Officer Seska shards as you tier up (full unlock at Tier 5). Blueprints come from the DTI faction store.
