Merge Radio Lease For Free

I can confirm that having multiple radio stations will give you more opportunities to pull in followers, as each independently check for new followers when their respective countdown's trigger. They also both help with happiness, I got 3 stations and it boost happiness a lot more than a sole one.

Unfortunately, no. Luck only modifies 3 things: Your chance of successfully rushing a room. The amount of caps received for rushing a room/work completed.

It also helps maintaining dweller happiness. One huge drawbacks is it also attracts Death Claws if you've 60+ dwellers, and it never gives you rare or legendary dwellers. So upgrading is totally not worth it.

Overview. The radio station transmits a broadcast into the wasteland in order to attract new dwellers. If the room is poorly managed, however, it may do nothing at all, or attract raiders and deathclaws. Its overall effectiveness is based on the assigned dwellers' Charisma.

Radio stations attract new dwellers from the wasteland, and can increase population happiness within the vaults. Vault dwellers that operate a radio station, will want a heightened Charisma score, in order to make the best use of these rooms.

All rooms can be merged into 3s (except overseer's = 2 only). The cafeteria and the living quarters can be painted/customized if they're merged into 3.

Radio Broadcasts - Assigning Dwellers to work in the radio studio will provides a happiness boost. Each 10 Charisma points in a radio room increases happiness for every dweller by 1%.

In addition to attracting dwellers, it can also raise the happiness of a vault. There are a few downsides though. It can attract enemies when not staffed properly, and the dwellers it attracts will only have 1-2 points in each SPECIAL stat. Compared to pregnancies, the Radio Studio may not be as useful.

Idea is dead :( Confirmed by Devs that Legendary Dwellers are Lunchboxes only.
