So I was thinking, and I came up with ideas for a new bomb line and new heavy sword line.
Bomb: A 3* to 5* bomb that produces a shockwave, knocking enemies back and dealing damage. The closer the enemy is to the bomb, the more times they'll be knocked back. Think like Magnus charge, except it knocks them away from the bomb, not just backwards.
Normal damage, no effects.
3*: Shockwave Generator
A bomb used to knock back enemies away from anything you don't want them near.
4* Shockwave Impulse
Originally designed to clear large messes, it was discovered it could also clear large monsters.
5* Shockwave (I'm not sure)
(I don't have a description either)

Heavy sword: No combo, just one heavy hit, but with 3 charge levels. 3* to 5*.
Normal damage, good chance of moderate stun.
First charge: Deals a much heavier version of the standard attack.
Second charge: Deals area damage (like a Trojan's attack)
Third charge: Deals heavy damage over a widespread area. Knight jumps a bit, and smashes ground with two hands on the weapon. Higher chance of stun.
I'll be honest, I don't have names or descriptions.
