Run value

Evaluate Astrolabe by when it appears, how often its effect triggers before the next boss, and whether it changes routing or shop priorities. The strongest relic is often the one that solves the deck's immediate weakness, not the one with the highest theoretical ceiling.

Compare this effect with the relic guides and current patch coverage before making a build-around decision.
