Rothgar sheds light on Guild Amenity Counts

Originally posted by Jindrack:
Level 30 guilds start with 5 amenity slots.
At levels 35, 45, and 55 you gain 2 amenity slots.
At levels 40, 50, and 60 you gain 3 amenity slots.

Starting at level 62 you get 1 amenity slot every other level. (Every even level) A level 80 guild would have 30 amenity slots.

All amenities are available right away. It is up to your guild to decide which ones you want to buy.

Tier 1 and 2 have a maximum amount of amenities it can hold, regardless of guild level.
Tier 1: 15
Tier 2: 25

Amenities Count is quite complicated…

30 – 5 amenities
35 – 7 amenities (+2)
40 – 10 amenities (+3)
45 – 12 amenities (+2)
50 – 15 amenities (+3)
55 – 17 amenities (+2)
60 – 20 amenities (+3)
62 – 21 amenities (+1)
64 – 22 amenities (+1)
66 – 23 amenities (+1)
68 – 24 amenities (+1)
70 – 25 amenities (+1)
72 – 26 amenities (+1)
74 – 27 amenities (+1)
76 – 28 amenities (+1)
78 – 29 amenities (+1)
80 – 30 amenities (+1)
