The infinity (but it’s actually just a long-lasting Iron Bear)
Fuel crisis what?
Do you enjoy piloting Iron Bear so much you wish it would never end, as its duration would be almost …infinite? This is a pilot build that offers no regard for Moze’s safety outside IB but handles pretty easily any endgame content: you will clear both true MTD and GTD with little effort.
The gimmick of this build is - predictably - extended Iron Bear uptime! However, I sacrificed some of the theoretical maximal uptime to achieve more damage and make the build gimmicky but viable. Fear not, you will still experience up to five minutes of Iron Bear duration (in certain areas).
Skill Tree
This build was designed to heavily rely on the new purple tree, Mother Bear, to create a build that is 1) tanky 2) free from the shackles of vampyr 3) offers a good deal of damage thanks to the addition of a Raging Bear com, that offers both fuel efficiency and damage the more you fight.
The loop here is pretty simple: Raging Bear offers both fuel efficiency and damage, while the Mother Bear tree offers healing via Biofuel , additional fuel and fuel refund via Nitrotrinadium Engines, and Never Gonna Give you up. Combined with the various bonuses on status effect and status effect damage, the more you fight the more damage and healing you get, and the more fuel you obtain to keep killing everything!
Class Mod
The ideal roll are + 3 on Deadlines for increased fuel capacity, and 2+ on Stainless Steel Bear to boost our health and damage and yet more fuel!
AS damage is a must-have passive roll, the other two can be whatever.
Artifact
Victory Rush, with a Snowdrift prefix; nice QoL when in a pinch or you have to move outside Iron Bear and mobility can come in handy.
Shield
Multivitamin prefix, and 75% extra health upon exiting Iron Bear anointment? And you can exploit it? Is this the sound of a 5.8 mln HP walking disaster that I hear?
Weapons
You don’t really need weapons here, Iron Bear packs a punch for the both of you, but why not help it in its path of destruction?
Any weapon would be viable here, as long as it bears the right anointment. Extra damage for my railguns? Heck yeah!
Additionally, you can use anything you want as a second wind weapon, if you happen to be downed outside IB. A Plasma Coil or a Backburner work wonders here, I speak from experience.
Grenade
This is honestly just for QoL. Applying rad DOTs will help you to dispose of enemies and possibly chain kills. A cryo version also works wonders if you want more crowd control. I’ve had positive experiences with both.
Additional equipment
This build requires a bit of micromanagement, especially in deciding when to keep pushing and fighting, and when to dismount Iron Bear and wait for your action skill to cool down. But what if you are impatient or in a pinch? Don’t worry, I got you covered!
This is a totally optional step, but you can equip a random low-level Sellout and set yourself ablaze. Why would you do that, you ask? Because you can com-swap to an Eternal Flame, ignite yourself and immediately reset your AS cooldown! Then, get back your Raging Bear, re-equip your Infinity and go back to Iron Bear!
Finally, you can see here the build in action
Special thanks to Mad Glenny that helped me brainstorming the build, and the guys at the Borderlands Retirement Village discord server!
