Heat Battery Core:
When equipped all heat you gain in a dungeon is placed within this device. All of your items gain no exp, and all of it is placed within this item.
Your heat is reduced by half when you do it, so essentially half the energy you would have gotten is lost, but there's 2 pros to this.
A.) It can be sold, it's not bound on equip.
B.) You can pump all of it into a single item.
Have an item that's t3, but you don't want to waste an equipment slot and most of your stuff is still not level 10? Bam.
Unsure if there'd be a limit, and where it would be put at, but that's for balance.
Shield Explosion:
Every shield can charge.
When fully charged your character slams his shield away, and the particle effect of his shield breaking is shown. (Although it's not broken.)
When done you blow away everyone within a T1-2 bomb distance away from you, but no damage is done. This is a utility aspect done to push monsters away, not to kill them.
"But sir! You can shield enemies and knock them back!"
True, but this is relevant to monsters "touching", this would effect all monsters around you. So if you know you're about to get surrounded by a BUNCH of enemies, and running up spamming shield isn't going to be much help knocking back, and neither is cutting your way out of the situation, blow them all away. No damage is done, not to them or you.
If you truly think that's OP, then make it to where it breaks your shield upon use, so it's high risk high reward.
So the sheild has the trojan attack buff blast? I could kinda understand having that on sheilds, but it could get hindersome to have allies knock them right back at you. It would be better if there was a bomb that would do that, creating a kind of safe zone. Then it kinda takes out the problem of everyone sheild blasting at once. Heat battery makes perfect sense though and has been suggested inf. times.
