i think we should think about some area denial items to help break up death balling and things of that nature.
to start off, we should think about an orb that generates electricity and causes a damaging electric shock to whoever comes too close. like a tesla grenade type deal. of course damage and duration ect would need working for balance but we are just brainstorming here.
This could work well as a type of land mine. It could deal AOE damage and maybe even hold who ever tripped it in place for a bit. Future bear traps sound exciting, and could also lead to a minesweeping item/internal.
Hmm.... EMP turret of some kind? It wouldn't be a pulse like the pucks, but rather would should emp bullets, with a cool down time akin to a secondary weapon.
DISCLAIMER: This could very easily be OP if not done right.
The bullets sound too OP unless they build up some sort of bar, which i doubt the devs want to program for only one feature to use.
