Referring people to the wiki just so they can play the game is a Bad(TM) idea. It's an already complex game, forcing people to visit an external website during the game so they can get information is going to drive some people off.
An in-game encyclopedia, like in Civilization, might work okay if it can be implemented properly. Past that, for golems for example, the energy cost line could say "Requires 30,000 energy (x energy on Golems: Medium) before it comes online.
For the Spire Blade Spawners, what can be said for each mark is that the blades do "between 100,000 and 600,000 damage, depending on combat style and ship caps." That way players have a general idea of the min/max, and will likely be able to deduce how much damage output they're likely to get depending on their game style.
