Throwable ideas

So, what we have in mc-war's throwing arsenal is pretty limited. We've got a tomahawk.. And a flashbang.. And a grenade. That's it. So I want to try to expand on this tiny arsenal by adding three new chuckable weapons of tactical and lethal status, let's begin.

Gravitation pulse grenade
Classification: tactical
Damage: 2 hearts
Effects: pulses three times, each pulse pulls everyone inside a five by five block radius into the center, the grenade pulses once every second before exploding in a tiny explosion in the center which does a medium knockback (outward force, five blocks)
Uses: lining up hard to land shots like RPG shots or python killfeeds, in a super awesome skillshot you could pull people off ledges

Energy blast
Classification: lethal
Damage: 20 hearts
Effects: essentially a single shot raygun bolt (without the explosion) this weapon hits it's target instantly. The twist on this is that it doesn't stop with one player thus making collateral kills possible.

Shockwave emmiter
Classification: tactical
Damage: 5 hearts
Effects: upon tossing this small device (and waiting for two seconds) the grenade with blast all enemies back several blocks (depending on distance to the grenade). This is exellent for blasting people out of cover or into a bad situation, this could also be used defensively as a means of giving yourself a few more seconds to escape from a bad situation

And those are all three, please keep in mind that these are brainstorming ideas, if you don't like them go easy on me alright? Alright. Let the feedback commence!

 

This is amazing
Yes, I hadn't really thought of the crossbow ultra kill until now, that's powerful man.. Wow

Balance.. Care to explain some of your ideas? I thought I did pretty good at balance myself but I'm obviously not the only one with ideas here. So yeah, hit me with some ideas people
