Good luck out there Thanks for your helpful response! Good luck to you too, Commander. it will produce an additional power of 7 (for a total of 10). Both the power relay and the comm stations can use 2 grims. XCOM 2 Avenger Base Building Tip Avenger layout xcom 2 wotc Due to the required power cost, the power relay build on the first exposed feed coil and with the staff of an engineer to further increase the output. In those 4 spots you want Resistance Ring, Power relay, Comm station and 1 freebie.

I've been able to build a lot of stuff at half cost as well. My Skirmisher is dealing stupid amounts of damage due to his bullpup getting boosted. Also I've heard a lot of people skip the lab, but lately I've been building them and not only do they increase your research speed but they also seem to increase the chances of breakthroughs which can be a HUGE bonus. Build what you need and what you can when you can. The PSI lab upgraded costs more than that.ДЄs far as build order goes, that's up to you. Reason being is that power coils make those cost ZERO power, but if you build a power relay on a power coil then it's only a +7 power.

I usually save the power coils for the PSI lab and the end game thingy that is escaping me right now. In the top corners I put my lab and the GTS schools, since non need for engineers.
