WarbringerHey guys, KallTorak here! I'm an Off-Meta creator with an affinity for silly goose time builds! This is my Ironbound Warbringer guide for leveling through the campaign & end game.
Why Play Ironbound?
Ironbound is a new bow with a very cool effect. Arrows return that pierce enemies with fully broken armour. A lot going on here but the cool part is arrows will return! This is a really powerful and fun effect with incredible potential. Using skills like 
Ice Shot makes both clear and bossing very easy. The bow is very versatile though, many skills can be used to play it such as 
Spiral Volley and 
Snipe.
Ironbound has very interesting scaling with the fact that it scales off block! You do increased damage based off your block chance. This is very interesting for bow builds since you normally dont block at all with them. 
Warbringer carries here with 
Turtle Charm increasing our block cap to 75%. No other class is able to achieve this high a block chance. When pairing Ironbound with 
Rearguard you are very easily able to hit the block cap. Warbringer also does a good job of automating the pierce effect with 
Anvil's Weight and 
Passthrough Rounds.
Throughout the game we are incredible tanky since we are armour stacking to increase both our block chance and our dps. In late game we can do a full evasion swap to 
Hyrri's Ire making us run around with 75% block, 80+% evasion, a bunch of deflection, 2k+ life, and the new ward defense. Defensively this build is very fun and unique!
FAQ
To get 
Legacy of Ironbound you need to acquire 
Aldur's Legacy. Use it inside a random 
Ironbound to get Legacy of Ironbound.
DO NOT socket it into any random Ironbound. Currently Legacy of Ironbound is very expensive. You want to make sure you put this into the ideal bow for your setup. In deep late game we have the ability to drop Rearguard and use a rare quiver. You need 14% block chance with block with ideally 6% of armour to block for your bow to pull this off with no extra investment besides armour.
If you do not care about giga min maxing and swapping to a rare quiver, slap Aldur's Legacy into a 3 socket Ironbound with 2 to 6 adds physical damage. If you want to min max wait until you have the right ironbound. If the price of Aldur's Legacy drops in price, do whatever you want.
Do NOT sway to mirage god early. If you swap early your damage will be awful. Don't start scaling mirage archer until you noticing it doing really good damage. Then start slowly scaling up the amount of them you can get. If you aren't giga juiced probably wait until 90+.
Hateforge make sure to get one without lose all rage when reaching max rage. This will brick your dps.
