Where do these numbers come from?
The factual fields in the original 305 unique base-game numeric rows (one identical duplicate Erdtree Seal source record was removed) are a compact derivative of the open-source Elden Ring API community dataset, source revision 1d2626c. Its API source declares MIT licensing, but this does not grant rights to unrelated game artwork, writing or proprietary assets. We exclude all source imagery, descriptions and lore text.
Three visibly inconsistent numerical entries were individually cross-checked with published weapon references. We track 102 Shadow of the Erdtree weapons and shields: 102 with +0 source-reported base-attack arrays (69 individual weapon pages, 33 wiki class comparison tables), including Stone-Sheathed Sword's disputed 89 +0 candidate versus 119 headline and conflicting 3.5 versus 5 weight; it remains excluded from trusted damage and load calculations. Three of the 101 records contain an explicitly unknown (?) scaling letter rather than a guessed grade. Six weapons have community-published +0 to +10 base-attack tables. No reinforcement scaling coefficients, affinity profiles or total AR are certified. Eight extra Tarnished Pack entries have named public roster corroboration and source-reported requirements and weights in a Regulation 1.17.3-labelled equipment reference; all eight have sourced community +0 attack, critical and letter grades (three individual wiki pages, four named wiki class table rows, and Ritual Thrusting Shield's separately corroborated 135 physical, critical 100, D/D scaling). Ritual's reported weight/STR requirements remain disputed among secondary sources, so load/wield checks remain blocked. The patch-labelled secondary site lists *max-upgrade* attack and is never used as +0. Real-game screenshots are not required for the user-approved Tarnished.dev v1.17 comparison. Other entries are not claimed to match the current patch. Source-code attribution and corrections are documented in the repository.
