unless i have more than 1 or 2 levels to go up i dont empower, i mean why spend a ton of gems boosting a druid to lvl 3 when you can give him a thistle mace and why spend a ton of slaves when you can get a brazen vessel

(unless you really need to research something before construction of course)

You need to get the druid to level three so that the thistle gets him to level four = lamia queens and treelord staff. Or in the case of the lizard shaman, empowered to n2 he can thistle mace, taking him too 3n1s, getting him to moonvine bracelet, which takes him to 4ns1.

With blood, using all possible boosters you can get +4 blood. So unless you have a b5 mage without empowering you cannot, for instance, get demon lords. Also, you often have only b1 mages, so taking one to b2 to start the booster path is common.
