As of now, Tempest Bell's Shocwave part is just in-game damage number with an unrelated(?) attack rate

Describe the solution you'd like

Tempest Bell shockwave should be

• Included as a buff to other skill (such as Whirling Assault) to calculate it's hit rate / Bell
• With 0.3s cooldown
• With 30% elemental increase per "Is enemy X? (elemental ailment)" modifiers
• Average of 3%/hits it can take increase (15% at base 10 hits)

Possible more complex implementation of the latter:
3% * (Bell Duration / Skill Hit Rate/s) capped at Hits Before Destroyed
either an average of it or a range

No files, tests, or entry points are named. Start by locating the Tempest Bell and shockwave skill calculations, then determine how buffs, cooldowns, elemental-ailment modifiers, duration, hit rate, and hit limits are represented; done means the requested behavior is reflected consistently in the relevant calculations.
