How do you obtain the grisly pointman title in Borderlands 2

I have had the POINTMAN class mod for about 10 levels and i wanted to change it to GRISLY POINTMAN but i don't know how. I have heard that you must add skill bonuses that come with POINTMAN to last ditch effort but i do not have that option. Could someone please tell me EXACTLY how to obtain the GRISLY POINTMAN title. The exact specifications of my class mod is: Level requirement 12, Health Regeneration +2.6, Max Health +69 THANKS!
