How it drops
The Grounding Spire is a rare unique for the shield slot, always on a Tower Shield base. A rare unique, power grade 2 of 5: it falls 4.4× less often than a standard unique. Uniques fall from the Risings; a floor drop is one only once in 100,000. Inside each tier a grade 5 falls 8× less often than a grade 1. Only one copy of a unique can be worn at a time.
Stats
Uniques roll a fixed set of affixes chosen to serve the power; only the values roll, from the depth the item drops at and its quality. Below is The Grounding Spire exactly as the game rolls it at quality 100, at three depths.

Percent affixes are fixed at a given quality; flat ones grow with depth. Quality runs 50–125% and multiplies every line.
Builds it belongs to
It lives in the Conversion (defense) family of uniques, alongside Pyre Ward, Stormsipper, Flesh of the Abyss, Transcendent Carapace. Stacking uniques from one family is how a mechanic is pushed past what affixes alone allow.
