Why shard the helmet? You should have kept it to infuse one of your legendary helmets.
And you got 4 engrams from 10 coins? Lucky boy, most people only get 1 or 2 engrams for that many.
Oh well still 30 odd 3 of coins so next time I'll keep that in mind and use it to infuse something. Thanks for pointing that out as I'm not quite familiar with the whole infusion thing myself.
If I understand it correctly, to infuse say the suros regime rifle which is 290 attack, I would need a weapon or armour of the same attack to infuse it right??
