Wanna have fun on survival? Try this wrench build.

[[OCN] John Wick ~ Rabbit]

Basially you can pretty much kill anything in the game with no problems except the big daddys, because they take 75% less damage from the wrench. But down below you'll see my set up, and you can mix it up however you like.

Plasmids

Your main plasmid will be electro bolt 3 other than that choose any other plasmids you want to use, but you'll be using electro bolt 3 more than anything for the 1..2 combo with the wrench.

Physical tonics

Sport boost 1 and 2 because they stack and also a must for the wrench.
Eve link 2 for obvious reasons.
Natural camouflage is a good choice.
Bloodlust is a must have for the wrench.
Last one can be anything, but i chose eve saver for obvious reasons, because lvl 3 plasmids use a ton of eve.

Engineering

For these tonics you can choose basically whatever you want - whatever suits your playstyle, because they do not benefit the wrench at all.

Combat

Wrench Jockey 1 and 2 for obvious reasons plus they stack. Must have!
Damage research 1 and 2 again for obvious reasons for more damage plus they stack.
Frozen field 2 is a must have not for the less damage from cold, but the ability to allow the wrench to freeze enemys.
Armored shell 2

Other than that you could replace armored shell 2 with whatever you wanted. You could use wrench lurker 2 for the stealthy approach, and even goes along great with natural camouflage if thats your style of play. I'm using this build on survival with vita chambers disabled and it's working out really good, but just be sure to save often.......just in case.
