I agree with u guys lemme help u got 2 chances to strike with ur hammer so u have two lightning each one deal half heart or a heart depending on how close the target is,then after u strike both of them u get fire resistant for 4 seconds and there will be a fire around u in 4 blocks away or u can cancel the fire thing and add absorption 1 for 4 sec
This kit surely needs a buff. There are many great ideas above my comment, so I'll say another : After a kill, you have 5% chance to get Speed 1 for 10 seconds or Regeneration 1 for 5 seconds.
