Ok ... this question actually comes up a LOT.
Tooltips update based on the weapon you're currently equipping.
If you have no weapon equipped, almost all abilities default to scaling with STRENGTH (there are a few exceptions of course).
If you equip a wand / staff, all abilities would list as scaling with INTELLIGENCE.
If you equip a dagger / spear / bow / crossbow, all abilities would list as scaling with FINESSE.
If you equip a sword / mace / ax, all abilities would list as scaling with STRENGTH.
However, the majority of Scoundrel abilities specifically require a Dagger, which scales with FINESSE.
Also, off hand only gets 50% of the normal benefits, so a weapon that uses a different stat that the primary weapon isn't as strong as the main hand weapon.
