Finally upgrading my Rainbow Habitat to Lv. 2.
Gonna use it for certain Heroic Dragons if they don't fit into the other habitats I designated.
Those dragons at the moment being Tidal, Octane, Tech, Commander, and Relentless.
Going off on a tangent: So, the way I structured my Islands is that whatever a Dragon's best element is for gold production, that'll be where it's placed.
For example, High Comet's best habitat is the Legend Habitat because compared to Flame, Ice, and Light, Legend Habitats produce the most Gold.
High Super is placed into a Pure Habitat, High Feral is in a Primal Habitat, and in the case of High Frozen, it was a tossup of either Pure & Primal (they look to produce the same amount of Gold).
Relentless's best Habitat was Metal.
Octane & Tidal's best Habitat was Dark.
Tech & Commander's best Habitat was Light.
The Rainbow Habitat beats out all 3 of those combined in my eyes, so that's their new home.
Back on topic: I hope I can get enough Tokens to get the Habitat to 25 spaces.
