Just finish all the reward stages. So far found 3 Valravens.
My opinions.
- If you don’t have the weapon yet, go for it.
- If you already do, buying just Tier II might be enough to get all rewards. Tier III for more garanteed result.
- Keep clearing all rooms seems to be the best strategy.
- It ended exactly at Level 100, perfect level to farm to me, while still easy to get the fraction team renown.
- Leaderboard in this mode is the “Loserboard” in its purest form.
