Click the command block so see what command is inside. Just go on Minecraft : Bedrock Edition and enter these commands into the the correct command blocks. Press space to close the command Blue = Repeating Command Block Aqua = Chain Command Block Orange = Impulse Command Block Red Line = Always Active Black Line = Needs Redstone Arrow = Connecting Command Blocks
I made these myself :) NOTE : For the repeating command block (the blue one) add a redstone clock that lasts around 1 second, to act as a cooldown for the attack. Command 1 Summons the vindicator (mage) Command 2 Gives the vindicator the mage tag to identify it Command 3 Give the mage a stick to suit the theme better Command 4 Give the mage its special magic attack
