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 broken and become unusable for 3 turns or until the fight is over, after which it is repaired (whichever occurs sooner).
Sentinels can be bought and upgraded at the Sentinel Shop map node. New sentinels cost a minimum of 150 star shards, and upgrading a Sentinel always costs 150 star shards.
When sentinels are offered to the player, the sentinel level 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.
Sentinels offered at level 3 and above always come with a random innate buff given to them (such buffs are reapplied when repaired, much like Stasis Clock's Light Shield).
