I was wondering if it is possible to kill the dragon so why not kill Creepers.
.... seeing mod effects like dragon murder and aswell Xray or treeAssist,
I combined it should be possible to hit a creeper with the tool in your hand - as long till he dies.
... but without being in range - maybe directly after his spawning or if he is getting closer than 15 blocks ... ???
Xray is able to manipulate my movement - to fly and to speed up - even in survival Servers that don't support that!
treeAssist is farming trees automatically - by using my diamond axe - even if I go away or switch to other tools.
dragon murder kills the dragon after spawning with explosion damage.
I think my diamond sword should be able to kill every Creeper entering my area (let's say 15blocks) automatically while I stay focused on my building progress....
