Sections

If you explore an Era with a brigade of lower Ranks than recommended, you will have a lower success rate, however, if its Rank is higher than recommended, you will have a higher success rate.

Eras will be divided into four sections (expandable when there are more eras):

Section 1: from Era 1 to Era 10: Rank C is recommended.

Section 2: Era 11 to Era 20: Rank B is recommended.

Section 3: Era 21 to Era 25: Rank A recommended.

Section 4: Era 26 to Era 30: Rank S recommended.

Guilds with sufficient Skill Points will be known as Veteran Guilds, these guilds are more likely to carry out successful exploration on less dangerous eras. Guilds will have better chances when facing problems on less dangerous eras, this increases your success rate by 2% per era when traveling to a lower level era and will accumulate as you go down Era Level. The Veterans guild has a cap on the success rate it can achieve on each eras stretch.
