Compare the listed Antique effects

Da-Ren lists +300 Operator Shields and a +30 bonus for each Unairu School Mod. Evir-Ti lists +60% Operator Jump Height. Metem-Erun lists +30% Operator Sprint Speed and +5% for each mod from a unique School. These effects concern different stats and have their own listed conditions; they do not add to Lorun-Tash’s Armor bonus.

Limitations and tradeoffs

  • The listed effect is Operator Armor; shields and movement bonuses are not listed for Lorun-Tash.
  • The final rank step costs 640 Endo and 20,000 Credits, in addition to the earlier listed rank-up steps.

Common mistakes to avoid

  • Converting +400 Operator Armor into a damage-reduction percentage without a supplied formula.
  • Assuming Lorun-Tash also grants shields or movement bonuses.
