 description: >-
-  Auxiliary function to simplify registering EFFECT_FLAG_CLIENT_HINT to players. (Card c) is card that creates the HintMessage,  (int property_code) are additional properties like EFFECT_FLAG_OATH (PLAYER_TARGET and CLIENT_HINT are the flags registered by default). (int reg. player) is the player that is registering the hint, to himself (int s) and/or the opponent (int o), with a description called from a string defined in (str). Additional resets, other than the default RESET_PHASE+PHASE_END, can be passed in (int reset_code) and its reset count (int ct).
+  Registers an effect that applies a hint on a player(s) which is visible when you hover over a player's info box at the top of the client. Typically used for effects that are scripted to affect monsters but will also apply to any appropriate monster that is placed in the relevant location at a later point (e.g. "Exosister Gibrine").
