I just found a amplifier of Anti and I need know if I need anything for it just like the technique amplifiers.Or can I just simply equip it...
yep you need a barrier to use it with before you can equip it. It could be a good asset but it wont be a normal barrier for every day use.
There's a certain amount of times you can use it?
no but the increased range of anti isnt needed most of the time.
the stats are bad so youll take more damge from enimies.
Amp of Anti + Assist Barrier = Anti Merge, 2x Anti range. It's stats are low and it's basically useless (especially offline) because Anti's range is short already. It is a nice find though.
