Fountain of Necrotic Might Upgrades
For reference on the pre-U12 stats, see Ascension Chamber loot history. Note: Upgrading the Quiver of Alacrity will destroy any arrows/bolts it contains at the time (ref). Unknown if this happens for upgrading from the old version to the upgradable base version, upgrading from the upgradable base version to the Striding version, or both.
 * For all items with clicky charges except the Litany of the Dead and Purging the Pantheon, the altar claims the items gain more charges than they actually gain (the amount of extra charges you don't get is equal to the base amount). This is likely just a display error, but could be intended that they do gain these charges. Either way, its a bug.
