Description of feature request

Over time, some blocks could be turned into their tainted variants when under the wither storm for long enough, and the taint could spread across other blocks as well.

Perhaps tainted mobs could gather on tainted blocks and form tainted flesh mounds (clumps of tainted flesh blocks) that have tentacles that grab and pull in mobs that get too close, and send out the occasional sickened mob to attack players.

Well this is a good idea for something like say Sculk Horde this doesn't work with CWSM
