Power Boom

Base duration: 2.5s
• Increases melee physical attack damage by +10% (unique).
• 'Power Boom effectiveness' modifies the damage increase.
• Power Boom only works with Swords, Axes, Spears, Maces, Knuckles, and Staves by default.
• Multiple instances add to the duration.
• Duration cannot stack beyond 60s.

[Notes]
• If multiple active applications have different Power Boom effectiveness levels, the highest is used.
• Daggers, Instruments, Whips, Books, and Katars cannot receive Power Boom by default.
• You can still receive Power Boom when dual wielding a valid weapon with an invalid weapon, but the effectiveness and trigger rate are halved.
