This is a suggestion for a total revamp of all the Gremlin weapons available to knights. I'm open to suggestions of changes, but I want to keep the weapons as close to the gremlin functions as possible without breaking the game.

Thwack Hammer
The Thwack Hammer revamp will make it the fastest "Troika" based sword in the game, and it will completely change it's charge attack. Upon unleashing your charge attack, your knight shall make a one handed swing motion. After the swing animation is played half way, it will stop and the hammer will fly forward. The hammer will act like a boomerang, flying forward to its maximum distance and return to it's owner. During this attack, you cannot switch weapons or use the hammer. The hammer can strike multiple enemies multiple times during the charge attack until it returns to you.

Weapon line:

2* Tenderfoot Thwack Hammer

3* Ironclaw Thwack Hammer

4* Darkfang Thwack Hammer

5* Crimson Thwack Hammer

Wrench Wand
The wrench wand keeps it's basic functions and charge attack until it becomes a 4* weapon. The damage remains normal, because let's face it. There aren't enough normal useful items in this game. Upon reaching 4* and 5*, the charge attack for this weapon changes. You seem to have fixed the wrench wands healing crystal, but since you aren't a gremlin rocket scientist you're not sure if it's fixed properly.
The charge attack for this wand now generates a bubble around your knight, other knights can also gather round and stay in the bubble as well. However, the bubble no longer heals and only has 1/3 of the health of a gremlin mender bubble. Knights who enter this bubble cannot leave it and projectiles cannot pass through this bubble. Knights in the bubble also receive a low defense buff for 5 seconds, 5* gives you defense buff for 10 seconds. The buff CANNOT stack. As soon as the bubble pops it buffs all friendly units inside the bubble, and pushes away all unfriendly units dealing no damage to them.

2* Tenderfoot Wrench Wand

3* Ironclaw Wrench Wand

4* Darkfang Wrench Wand

5* Crimson Wrench Wand

Shield
Yes, the darkfang shield that is dropped from gremlins should be redesigned too! It will keep all the same stats, however when it becomes a 4* shield it now offers a Bomb damage bonus low! Upon reaching 5* it becomes Bomb damage bonus medium. Because there's no bomb shield.

2* Tenderfoot Shield

3* Ironclaw Shield

4* Darkfang Shield

5* Crimson Shield

Obliteration Bomb (Deconstructor revamp)
This bomb uses normal damage, this bomb is a revamp of the Deconstructor and removes the construct damage bonus. Upon reaching 3*, the Obliteration Bomb gains a new effect! Upon detonating, it has a small chance to drop a smaller bomb nearby that has 1/3 of the explosion radius and deals 1/2 of the damage! 4* adds one bomb, and so does 5*. This bomb still uses the gremlin symbol when it explodes.

2* Tenderfoot Obliteration Bomb

3* Ironclaw Obliteration Bomb

4* DarkFang Obliteration Bomb

5* Crimson Obliteration Bomb
