Infested Block

Description
Infested Blocks are natural blocks that have been infected by Beckons and can deal a variable amount of damage (Increases with the Beckon's stages) to other non-infected beings if stepped on. They can also spawn certain mobs if entities are nearby.

They can be broken with any tool or bare hands and when broken with any tool will drop. They also have a custom sound for breaking, placing and being walked on.

After a Beckon is slain, all blocks infested by it will turn into Infested Residue.

Mobs
Blocks that have been infested by a Stage 3 Beckon have a chance to spawn a Kyphosis or a Sentry.

Kyphosis
A Kyphosis is a large, tentacle-like creature with sharp red spikes.

It will attempt to crush players and other non-infected mob that gets too close, dealing massive damage.

Sentry
The Sentry is a large tentacle-creature with limbs and a gaping mouth which it shoots out of.

It will attempt to shoot players and other non-infected mobs at a distance, dealing massive damage and inflicting the poison effect. Most importantly, it will completely melt down gear the player is wearing, being able to break even diamond armour in two or more hits.
