Ivanabot said:I do not have boosts because I could never get every dragon in the green (positive) so I just gave up, but if you read the description of each boost, it will tell you which dragons it will affect negatively or positively, if anybody else understands the boosts feel free to jump in and help out![]()
Boosts effect all the dragons on the Island where you put the boost building. They really are of optimal use if you are going to dedicate an island to gold production. If you are going to mix and match your dragons and habitats "for looks" then they are probably best either ignored altogether, or ignored from the point of view of what negative effect they are having on your dragons. The negative effect is actually not too great, so unless you are devoted to getting the maximum gold production, you can ignore boosts to one degree or another.
