Hi!
I was planning to give my bots some armour but can't decide which armour to give them.
Which would be best/better?
Iron
Steel
Ceramic

Oh and are Duranium and Carbon Fiber better than the ones listed above by any chance? If so, then which one is better? Duranium or Carbon Fiber?
Thanks!

It's been my experience that iron armour does quite well through lvl 3. So that would be my choice save the xp for core stats then when you hit lvl 4 add your rank. Endurance does a nice job of negating some damage as well.

Thanks man
