With stdWeapons.zh out in database, it`s possible to have custom weapon-related secret triggers. As for now, ZC`s Lens Hints quest rule only works with built-in secret trigger flags and does not work with custom ones. This script allows custom secret triggers in the quest without leaving Link clueless about triggering them if he had to rely solely on Lens of Truth.
The sript has support for combo type & flag hints (drawn on combo when Lens used), FFC hints (Draws hint on center of combo, if the FFC runs the specific script and the specific D value matches the given argument), and NPC (draws hint on specific enemies, like to show their weaknesses).

Requires stdExtra.zh and all it`s dependencies.
