Sentinel
A sentinel is an allied automaton that follows the Oracle around. Each sentinel has their own health pool separate from the Oracle and has a unique die that it rolls separately from the Oracle's pool. If a sentinel is fully corrupted, it will be destroyed and become unusable until the end of the current battle, at which point it will be fully restored.
Sentinels can be bought and upgraded at the Sentinel Shop map node. New sentinels cost a minimum of 150 star shards.
When sentinels are offered to the player, the sentinel will be the highest of the two following values: Lowest current sentinel level + 1 (an empty Sentinel Slot counts as Level 0), and the total number of visited sentinel Shops and Rewards (including Event Rewards) added together, then divided by two.
