Currently the health bonus versus the cost in terrasteel ingots is not really balanced, so my suggestion is to change it so the health bonus for each piece of gear is exactly one less then the amount of ingots required to craft it

This way, you end up with 3/4/6/7 (boots/helmet/leggings/chestplate) for the exact same total boost of 20 health, but this way it makes the per-piece health values more balanced.

Sounds good.
