hmmm....in that case maybe you should get rid of one, and change the other for a blessing, since you probably will have plenty of quanta early. only rarely will you have hand congestion. at least until you can upgrade them. and even then, the 15 pillars is probably plenty. especially once you upgrade, tower you play will immediately generate quantum making the ray of light kind of superfolous, since it is probably easier to get rid of then a tower.
