It's basically a jungle Sunfire. I'm not sure why top laners are taking it just for the HP bonus.

Because Cinderhulk has a bonus health multiplier. It's not about the damage really.

Cinderhulk is very strong for champions like Shyvana in particular also because if you go stalker's blade along with cinderhulk she gains a movement speed steal (you get faster, opponent gets slower) on a 40 second cd.

It also means you have a second smite on your team for greater dragon and baron control.

Finally since you take smite you can smite the gromp for his poison debuff so that when you are in teamfights it's like having a mini thornmail.

One of two things will have to happen for sunfire cape to become better. One, they remove the health multiplier from cinderhulk, two, they give sunfire cape a health multiplier, or three, some combination of buffs and nerfs to balance them out.

Sunfire does provide armor, but armor is so cheap now it's really not a big deal that cinderhulk doesn't have any, the health multiplier also greatly increases the value of items like Banshee's Veil, Randuin's Omen, and Spirit Visage for tanks as it continues to help them acquire more and more health.

depends on time in combat. if it takes long enough, cinder hulk does more damage, and can be build from machete

WHY WOULD I BUY THIS ONE OVER SUNFIRE?
