Fury Swipes stacks damage with each hit, so keep attacking the same target in fights.

Overpower gives rapid attacks, so activate it before bursting a target.

Enrage reduces damage taken and dispels debuffs, so use it to survive burst.

Ursa can solo Roshan early, so take Aegis to snowball.

Earthshock slows enemies, so use it to close the gap and chase.

Ursa is easily kited, so build Blink and BKB to stick to targets.
