Here goes my yet another attempt to create a tank build for domination, and this time I managed to come up with quite interesting gameplay. The build specialises in various damage overtime effects litteraly rotting enemies away, meanwhile heals tons of hp with regenerative armour and Tchortist Bioscrubber. You will be throwing tons of gas granates and slowly adwance on enemies lines.

Taste for blood
Psycho-temporal Acceleration
Hypertoxicity
Pack Rathound
Escape Artist
As weapons it uses bladed combat gloves with burrower poison and thrower gloves. You also need an energy knife as back up for robots.
Methatermics is optional and may be swapped for 45 PK, you need either electrokinetic imprint or fire aura to fight crawlers and I just prefer the latter.
Plaguemarine is quite a distinctive build and it's very interesting to play but I do not recommend it to new players(as every other tank build) because it requires a good knowledge of the game and is expensive as hell.
