Impact Echo 0.2.0: blast + wall echo

Slam them into a wall. The wall hits back.

• Hold to charge (0.8 s), release a ground blast: every enemy within 6 blocks is thrown away from you. The closer they stand, the farther they fly.
• Anyone slammed into a wall echoes: a shockwave bursts out of the wall, hits everyone within 3 blocks and leaves them Vulnerable (+25% physical & projectile damage taken, 4 s).
• No wall, no echo.

Install: drop impact-echo-0.2.0.jar in your Mods folder (singleplayer) or the server's mods folder.
