The Great Zeta Debacle

- Adding a tier in the challenge with 0-2 zeta mats (0 = 30%, 1 = 60%, 2 = 10%; for around 7 zeta mats per week this way on average).
- Higher chance of getting 1 zeta for ship challenge, to an average of 4-5 zeta mats a week
- Re-implement flash events, corresponding to the month rework/addition, with a 3 guaranteed zeta mats for first completion (like for phoenix flash event), for a total of 3 zeta mats a month
- Adding zeta mats as a possible reward for node 9 hard battles (with ~5% chance of drop, i.e 1-2 zetas a day with full crystal recharges and focus solely on these nodes)


With these, a fully dedicated player with a significant crystal income can get 1 zeta ability in a bit more than a week. Most average players will have 2 zeta abilities a month, which will still leave them with a full year to get them all, provided no new zeta ability is released. Considering there are more than 2 new zeta abilities released every month on average, it still means players will have to make tough decisions in the area.
