The weapon tooltip for (e.g.) the greataxe always states 80-100 damage, but the tooltip for the Split Man skill states 120-150 damage, whereas the tooltip for the Round Swing skill states 80-100 damage. If you consume mushrooms, the damage for Round Swing is updated to 112-140, but the damage for Split Man remains at 120-150. By contrast, when Killing Frenzy is activated, Split Man and Round Swing are both updated to reflect the +25% damage. Similarly, if the character using the weapon has a bonus due to a trait like Drunk, the tooltips for the individual weapon skills (unlike the weapon tooltip itself) are updated to reflect that bonus.
