Why Defensive Energy Crystal is S tier
S
Tanks and Vanguards open each combat with Shields equal to their full Max HP, then gain ten times their Defense in Shields after Stall (20 and Stall 40). Stall Aria runs it, and its runs beat almost every other Legendary relic.
Each relic is compared with the relics that reach you at the same point of a run, across the runs players share, and with the strongest published comps. Reviewed on patch 0.5.12; the whole ranking is on the relic tier list.

What is the difference between a relic and an item?
Items are equipped by a single hero and take up one of that hero's slots. Relics apply to the entire guild and do not use slots. That makes relics the stronger of the two when a build starts coming together.
How do I increase my team size?
Harmony Crystal raises it by one, up to five. So does each of the fifteen Mandate relics, but those require finishing an objective first, like dealing 15000 auto attack damage or applying 30000 shields. Pick the Mandate that matches what your team already does.
