Introduction
Leviathan the
Tidehunter is a very durable STR Hero known for his gamebreaking ultimate,
Ravage: many players think he's a dedicated initiator and doesn't benefit from extra farm after buying his
Blink Dagger,
but his built-in damage block and high natural STR growth make him a
perfect candidate for risky initiations and chases. He can actually farm
pretty fast thanks to
Anchor Smash,
which not only makes last hitting in the hard lane very easy but also
deals damage to ancient creeps, and his playing style varies according
to the item build: a
Refresher Orb Tide can basically solo kill the entire enemy team, while going
Blink Dagger into
Force Staff
makes you much more versatile as a scout and chaser (and sometimes
makes you able to save your teammates, too!). Expensive auras like
Pipe of Insight,
Shiva's Guard and sometimes even a
Mekansm are money well spent on such a Hero, and he's also a good carrier for a
Gem of True Sight.
Tidehunter is pretty straightforward. You generally want to run him either as a solo offlaner, greedy (i.e. not 'hard') support, or mid.
