MAJO Petra Build Guide – Live Origin Contact Testing
Quick answer
MAJO Petra build guide for the active September 2-9 Origin Contact with testing team shells, pull value, investment advice and verified unknowns.
Short answer: Petra is live on Origin Contact from September 2, 12:00 to September 9, 05:00, 2026 (UTC+8). Treat her as a live-testing SSR, not a finished tier-list lock: she may be worth testing if your core team is stable, but her final tier, best team and duplicate-investment value still need verified PvE results.
Petra Status
| Question | Current answer |
|---|---|
| Is Petra live? | Yes. Her Origin Contact window is active during September 2-9, 2026 (UTC+8). |
| Is Petra worth pulling? | Conditional. Pull only if Origin pity, role need and team fit are favorable. |
| Is Petra a final-tier unit? | Not yet assigned. Keep her in Testing until real teams are verified. |
| What still needs proof? | Skill scaling, weakness coverage, boss value, Tower value and replacement value over existing SSR options. |
What Changed After Release
Petra is active now. Any older preview wording should be read as outdated: the live decision is whether to spend during the active Origin Contact window or wait for stronger post-release testing.
The safest current read is conservative. Petra can be tested as a flexible SSR slot, but this page does not claim a best-in-slot build, PvP rank or duplicate priority before live comparisons are strong enough.
Live Testing Team Shells
| Shell | Why it fits |
|---|---|
| Carmen + Petra + Xuanji + Maro | Stable benchmark with frontline, damage and sustain. Compare clear speed and survival against your normal core. |
| Carmen + Petra + Patra + Peseshet | Magic-leaning shell for checking whether Petra improves AoE pressure or support coverage. |
| Garana + Petra + Peseshet + Dusan | Accessible test shell when SS roster is incomplete. Use it to test role fit, not to claim best-in-slot value. |
When testing, keep level, gear and stage choice as close as possible between runs. A Petra team should beat your existing team at the same investment before you move rare upgrade materials into her.
Should You Pull Petra?
Wait if your current team is still missing basic role coverage. Consider Petra if you already have a stable core, enough Origin Contact budget, and a clear plan to compare her against your current DPS or utility slot.
Do not spend saved pity only because Petra is the newest Origin Contact. Also do not max her before checking live kit behavior, weakness coverage and team value, especially with the September 9 update cycle close enough to change account priorities.
Investment Priority
Start with low-commitment testing: same level, comparable gear and repeatable PvE stages. Move Petra higher only if she improves a team you already use. If her advantage only appears with unverified assumptions or heavy duplicate investment, keep resources for the September 9 update cycle.
Evidence Notes
- Live banner state checked for the September 2-9 Petra Origin Contact window.
- The official August 26 notice verifies Origin Contact carryover behavior from Lomi / Lumi into the next Origin Contact, while the live banner state identifies Petra as that active rotation.
- The official producer letter previews September 9 systems, including PvP and Floating Law, but does not provide live rules yet. Petra should not receive a final PvP placement from that preview alone.
