Check out rzghuul's server if you have any more questions on Wither Defences!
To build an atleast decent wither defence you should follow these rules
No symmetry in terms of groups of 3 Blocks. (more info coming soon or in rzghuul's discord)
The the centere blocks of the witherbore should be forced to hit lava.
There should atleast an equal amount of lavasorces and watersorces. Better would be more lavasources.
No 1x1 Lava sources
If you have Flowing water have extra protection against fast bores
Have lava sources that don't have any water diagonal to them (this only works if water does not touch the floor).
have at least one lava scorce in the path of the witherbore that does not have water infront of it.
Test your wither defences!
