Understand Metem-Hakh
Useful when…
- Adding survivability to an Operator setup.
- Using a diverse School-mod loadout to gain the stated per-unique-School bonus.
Effect and condition
At rank 0, it grants +5% Operator Health & Shields; at rank 3, +20%; and at rank 5, +30%. Its listed +15% bonus for each Mod from a unique School is separate from those rank values. The supplied details do not define how the bonus is calculated beyond that condition, so do not assume a particular total or stacking formula.
Fit and investment
This is a universal-polarity Antique Mod for the standard slot, with zero base drain and a maximum rank of 5. Ranking it raises the Health & Shields value, while the unique-School bonus remains listed as +15%. Rank 0→1 costs 480 Endo and 15,000 Credits; the listed 4→5 step costs 7,680 Endo and 240,000 Credits. Those costs make a lower rank a reasonable stopping point if the added base survivability is enough for your setup.
Alternatives and acquisition
Metem-Erun instead increases Operator Sprint Speed and has a smaller listed unique-School bonus; Da-Ren gives flat Operator Shields and adds a bonus for each Unairu School Mod; Empazu-Shol improves Tauron Strike Initial Charge with a unique-School bonus. These serve different goals rather than being direct replacements. Listed sources include Rotation A of several Dark Refractory activities on Deimos during The Perita Rebellion, and commandeered Prime Warframes.
Limitations and tradeoffs
- Its strongest stated base Health & Shields bonus requires rank 5, with steep cost for the final rank.
- The unique-School condition rewards a varied School-mod setup; its exact total contribution is not specified.
Common mistakes to avoid
- Assuming the per-unique-School bonus replaces or is included in the rank-based Health & Shields value.
- Ranking to 5 without weighing the listed Endo and Credit cost of the last step.
