The most cool skill is his second one, ulsing a ghostship to draw the enemies if they try to escape. His first skill when activated make you have splash damage. His third skill is mark the spot,marks a hero and leaves an X in its area, after a few seconds(not sure how many) the targetted hero moves back to the X mark. His ultimate gives 2x critical for several seconds, realy neat to kill a hero quickly.
Here is more explanation about his skills:
-First skill is TideBringer
ASSUMING TIDE BRINGER IS AT MAX LEVEL
1 second after tide bringer when activated, it will deal about 300 damage to units in a 220 radius. After damage is dealt, it gives Kunkka an extra 60 damage and an 100% cleaving attack which affects units for around 500 distance. However, this buff only lasts for 8-10 seconds or 5 hits (Like Ursa’s Overpower) Great for farming.
-Second skill is Ghost Ship
Slows enemies hit with the ship and draws them closer.
-Third skill is X Marks the Spot
Marks a hero and leaves an X in its area, after a few seconds(not sure how many) the targetted hero moves back to the X mark. Use this to make the blinker enemy cannot escape.
-Ultimate Captain’s Rum
When you cast the spell, the targeted ally hero gains 20% bonus ms and a high (100%?) chance to crit for 2x damage. This buff lasts for about 5 seconds. Use it to kill enemy, combined with Mask of Madness, i think this skills is really great.
